I've been pondering whether it would be possible to create i.e. a 030/040 compatible but more compact and energy efficient turbo card for the A1200 that would fit nicely inside the standard desktop case? I don't know whether the processor chip needs to be its own separate entity but I think that the other chips incorporated on a turbo card could be embedded into single FPGA. Are there modern low cost versions of i.e. 68030 available nowadays? The use of FPGA architecture would also enable some peripherals like SCSI or SD card reader, if I'm not wrong.
I know 030/040 and even faster turbo cards for the A1200 are still relatively easy to find for a reasonable price but a modern approach to this peripheral intrigues me.
-
A 060 board is very energy efficient.
-
030 or 060 would be your best bet as the 040 was very inefficient, and also suffered heat issues. As for which was most efficient out of Blizzard/Apollo, I wouldn't have a clue I'm afraid.
Out of interest, why is power efficiency an issue for you?

@motorollin: I'm just thinking about the power resorces that a standard A1200 PSU has to offer. I do not know if the latter revisions (if such exist) of 680x0 are more power efficient than the ones that were used in turbo cards back then.
-
I remember seeing a 68030 based MacIntosh laptop. I wonder what kind of 68030 chip it used (a more energy efficient one, I would imagine).
-
If you were to get an L88M mask version of MC68040RC40A it would be cool to the touch even without a heatsink and at the fastest 40MHz.
Much lower temperature compared to the "boil an egg" ones that were used in the Amiga.
-
I'd probably use an XScale for this task, and run a 68k JIT emulator on it... or if I had some serious investment, then I'd probably use a Duron...

Like that would work... NOT.
What about the external BUS etc. hardware that you cannot emulate?
Before you know it you'd have almost created a 68000 CPU with glue logic just to get the square peg in the round hole!

Well, since the alien Processor would be the bus master of the Amiga system, I would expect it wouldn't be to interface between the ZII and HT (for the Duron) bus's with an FPGA which could house a few other core's, like USB etc...
-
The 68040V is designed for low power consumption.

The HT to 680x0 bridge would be almost as complicated as a 680x0 processor. Not to go into too much detail here... it wouldnt work very well / at all.

I am surprised that no-one has considered making a 2nd generation 68060 accelerator using Rev6 silicon (which can go upto 100MHz) and SDRAM like the CT60 on the Atari Falcon
Given the current high price of CS-MKIII I bet a run of 100 could be profitable.
-
It's a shame I'm making my first post on A.org and not using it to really add anything to the discussion but, ah well.
I too have been surprised by the availability of a 100MHz '060 card with an SDRAM DIMM slot for the Atari Falcon, while Amiga users are proudly displaying their 66MHz '060s (mostly only overclocked from 60MHz parts), and searching SIMM bins at computer fairs for that elusive 32MB+ SIMM that will work with their setup. :(
Thinking about it, I suppose a refresh of an existing design could be made, with the larger/cheaper FPGAs/CPLDs around now it probably wouldn't cost any more than the original, even considering that it would be a comparatively small manufacturing run. The problem would be finding who owns the designs now (and would be far-sighted enough to realise that they are no longer worth holding onto the rights), and finding anyone experienced enough to take such a design and confidently update it for the new logic chips around now and the ( admittedly few) new features that buyers would demand.
Maybe a simplified Viper 1230 design could be made available for solder-junkies to assemble themselves, but don't expect a do-it-yourself Blizzard PPC (6 layer board?) anytime soon.
*Hopes for a 2 sided, single layer schematic for a CD32 '060 card to be released tomorrow for free*
-
I have a two layer passive adapter board I made for CD32 that allows you to connect an A1200 trapdoor card.
The edge connectors are impossible to find ( or have a minimum order of 1000 ) which made it not feasible to release as a product.

-----------------------------------------------------------------
Are You SERIOUS??? where have you been??? Thats quite cool! imagine a 68060 in a CD32 or even a blizzaed PPC card!
....more importantly..I was always searching for someone who could create a passthrough on the CD32 that would allow the SX32 and FMV card to be plugged simultaneously. Or even an extra accelerator in your case.
The CD32 would be the ultimate Multimedia machine like that!
By the way, there were many upgrade cards for Mac that used the same exact connector as the CD32....even PPC cards....I once plugged a G3 card into my CD32 and it plugged perfectly........I tested it because I was considering unsoldering the edge connectors to make my Own SX32 passthrough to plug the FMV card.....never got to it......anyway I turned the CD32 on with the G3 card in it and fried the G3 card :-D my brother was angry and regretted giving me the card........but I didnt give 2 squats! I was just happy I had found a connector exactly like the Passthrough on the SX-1, SX32 and FMV card. even if it meant destroying a new G3 card wich I cared not much for. This was at the time when G3 Macs were popular around 1999?
-
I've got a couple more A1200s that could use some upgrading. I would not even consider buying an accelerator with less than a 68060, but I'd really like to see the fastest & most compatible ColdFire chip, if that were possible. Newer type RAM is a must. (Ultra)SCSI? Well maybe, maybe not. I've got a lot of SCSI peripherals and the Amiga was very friendly towards them until the A1200 & A4000 came out. It would be nice, but not necessary. Fast USB version 2.0 is a must, though. Would be nice to hook up an external DVD burner that way and any other peripheral, for that matter. Ethernet would be nice, especially if it could go faster than 10MBS. Firewire? Is that possible? The Amiga is a video computer. Ah yes, built-in MP3 is a must. Anyone else?
-
(just adding to the dream thread...)
also any new accelerator should have SATA as a controller, no more huge scsi cables with terminators and all the mess they create... SATA should be more than enough for the amiga, and I bet it reaches or exceeds amiga-scsi solution in speed terms...
-
But isnt it good to have a CPU on the HD like SCSI when you are dealing with low CPU systems like Amiga?
-
Anyone got the link for the 100Mhz Falcon '060 board?
RE. SCSI: It's a pain sometimes but it allows 7 devices to be used at very fast speeds without pestering the CPU.
Scanning and CD burning are probably best done on SCSI. That's what the industry uses.

I have one, running at 100Mhz. It needs a particular 060 mask, or it won't run at that speed (labelled 68EC060, but actually contains the whole shebang). Bus speed towards the SDRAM is 100Mhz too, so it's about as fast as the 68k range can ever go.
-- Peter
-
what are you talking about sata and cpu load? new controllers (like new IDE ones) use DMA for transfers like scsi. the problem is that there is NO amiga IDE controller that uses DMA AFAIK, that is why IDE is so much slower in amiga... even FastATA does not use DMA...
-

Bollocks! The chips need to be what is called a Rev6. They can easily identified because they are prefixed with MC (MC68060) AND here is the important bit.... they have a MASK number E41J written in the corner.
(http://www.amiga-hardware.com/display_photos/MC68060RC50.jpg)
The EC labelling has nothing to do with their speed capability. There are older MC68EC060 chips that cannot be clocked at 100MHz. The EC representation just means that the CPU was sold as a cheaper variant which is has a broken / untested MMU & FPU.
-
Interesting that there is a parallel 68k computing universe taking place with the Atari Falcon going 100Mhz '060/SDRAM...
:-D
What kind of software are Falcon users meddling with these days? Any famous apps/games?
-
Dude, they actually labelled some full versions as EC. Mine happens to be one of them. I didn't say that EC:s are capable of running at 100Mhz. I'm perfectly aware that this does not apply to all CPUs of that mask.
Perhaps I could have expressed myself a bit more clearly, however I think good manners does *not* include using terms such as "bollocks" when speaking to strangers for the first time.

The OS is open source, as is the GUI, so there is a bit of development there. Since it (sort of) complies to POSIX, it's fairly easy to port stuff from the un*x world which means that there are a few emulator/game ports.. It's probably similar to the Amiga scene, but with fewer active people.
-- Peter
-
alexh: You owe shoggoth a drink. May I reccomend this fine vintage from my cellar?
(http://www.winelabels.org/image/bollocks.gif)
EDIT: The Falcon sounds a real interesting bit of kit, I'll scour the web for more info!
As for energy efficent accelerators I'd say a Blizzard 1260 with 16MB SIMM would be least hungry. The '060 is 3.3v as opposed to the 5v '030 and '040. Not only is the voltage lower but it doesn't require an energy sapping (and noisy!) fan to cool it.
A newer SIMM of 16MB or more may well have 4k refresh DRAM chips which are less energy guzzling than older SIMMs using 1k or 2k DRAMs (although 1k/2k DRAMs have higher refresh speeds - 16ms/32ms vs 64ms). Laptops of the time would have used 4k refresh DRAMs.
Going up to 128MB/256MB though would probably be eating into the power!
;-)
-
I second (third? fourth?) the suggestion that some enterprising soul resurrect the design of one of the out-of-production 060 cards. Amiga users would lap this up, even if it was just a straight-forward re-issue of the original design. If it was a slightly updated design, with newer chips that performed the same function (perhaps even faster) it would be a real seller!
(Just make sure there is an A3000/4000 version so I can get one!).
-
Problem is digging up rev. 6 060:s. Czuba sort of vacuum cleaned the world for them.

I don't see where you get this idea that it will take "almost a 68000." Just look at any A500/A600/A1000/A2000 accelerator and you'll see that the 68000 state machine is at most a handful of oldschool programmable logic and TTL chips.
A bus is a bus. Even a modern x86 CPU with hundreds of pins can still be interfaced with the slow 8-bit wide EEPROM that holds the BIOS.

Not officially.
The price for Rev6 68060's on ebay from my seller has almost doubled in the last 2 years. From 60 euro to over 90 euro.

've been pondering whether it would be possible to create i.e. a 030/040 compatible but more compact and energy efficient turbo card for the A1200 that would fit nicely inside the standard desktop case?
If you did a board that ran totally at 3.3V then it would use less power. Freescale make a few 3V 68K's... I havent looked but as the 68060's core is 3.3V I bet the IO bank could be run at 3.3V too.
You would just need some buffers that can drive a TTL signal and accept 5V logic levels.
As for sticking an FPGA on board for SCSI or SD, yup it could be done, opencores.org have a few designs as do Xilinx and lattice. (Heck a PIC can interface to an SD card)
As for making a more compact card... well I dunno, unless you can get some of the old 208 pin QFP 68060's that are out of production now the 060 is always going to stand tall.
The rest of the logic would be surface mount and chips in the TSSOP and TQFP packages stand only a few mm off the board. Space wise adding connectors is what takes up the space, mount the memory on to the PCB (8 chips normally) and you would save yourself a bit of space.
You could go mad and do a 8 or 10 layer PCB and make a card that looks more like the Amijoe was, a card full of chips with the tracks routed on the layers below but then your talking about a lot of expense.
I would say KISS, 3.3V the CPU board, mount some SD-Ram on the board itself (available from Digikey) and if you want SD card readers or SCSI why not add a USB host chip and use that? I think the overall cost of such a board would be low, except the 060, but you could sell it with a socket so people could hunt around, ripping Atari's to shreds for the 060 ;-)
-
well, I got a rev6 060 from amigakit.com and is currently sitting on my 2nd csppc that has socketed oscillators.

You'd need an FPGA/CPLD for your 680x0 bus compatible SD-RAM controller. As there are non in existance (except the CT060) you'd have to design one or ask Rodolphe of Czuba tech if you can license his HDL source code.

It is still too complicated for anyone not in the electronics industry. You yourself tried to do a Coldfire board several times and was never totally successful.
Even for someone who is in the electronics industry, regularly makes multilayer PCB's, can get good prices and understands the design constraints, producing volumes of less than 100 would still not be economically viable.
It is unfortunately a non starter :-(
-

Actually there is, I dont have the spec here at work but give me a couple of hours and I will be home.
That said a CPLD one would be easier, Xilinx give away the VHDL code for use on Xilinx chips. (They have DDR ones too but on a 50Mhz bus thats pointless)

Well you could use the Haynie archive PAL code from the 3640, stick it in a CPLD (using Abel) and then alter it.
The full design is available, even though the 3640 wasnt the most pimped up CPU card ever made.

Well I ordered a slab 14.5" by 10" yesterday, two layer (yup, not suitable for high speed CPU designs, 4 layers would be needed but..) with solder mask and silk screen, inc postage and all fee's for £70 all in. fit as many designs/boards on as you can.
It aint an expensive thing to try if someone wanted. :)
plus you can still buy PLCC CPLD's so you dont have to play with tiny SMD things.

Hi Oli,
Just make us a good bit of kit, I`d buy a couple :)

AMD CPU's also include an on chip memory controler so support chips could be kept to a minimum.

There are free opensource SDRAM controllers, but it wont have a 680x0 bus interface. It will have AHB or wishbone or something.
Xilinx give away the VHDL code for use on Xilinx chips. (They have DDR ones too but on a 50Mhz bus thats pointless)
Doing a good quality 680x0 bridge will take some time. Czuba tech is very nice and has posted several FAQ's that will help but still it will take several weeks worth work (a few hours a day) to perfect.

The A3640 is a CRAP card. It doesnt have a RAM interface and it doesnt support 68040 burst mode. Couple with that PALASM isnt the easiest thing to reverse engineer.
Is the PAL code available as source? Is it commented?

The logic on most Amiga accelerators is JUST a very simple 68k to DRAM bridge, plus some sort of asynchronous buffer from the higher speed 680x0 bus to the 7MHz Amiga bus. The two are VERY a like (and were designed to be so).
A non 68k bus to Amiga Bus will take a lot more glue logic, speed bridges, buffers etc. No one will ever attempt this. Too much work. No reward.

1) An IO mapped eprom is hardly the same as a multi-master tristate bus but hey...
2) The x86 Northbridge (or is that southbridge?) has like 2,000,000 gates or more to convert between buses and standards. Obviously I am not saying you would need even a fraction of those gates, but it is not going to be a sunday afternoons work.

Yeah it's a lot of work... which is why I said that if there was some serious investment, that is the route I would take.
Right now, there is NO chance of any more hardware for classic hardware as any new hardware is going to cost more than it could ever sell.
-
Looking at the course this thread has taken I feel the need to add my opinion on some issues raised. Cos I'm so egotistical that I'm sure you all value that opinion highly. ;-)
All those people saying that a new accelerator would not be commercially viable, you're damn right. No one could start a project like that expecting to make a nice profit at the end of it.
Then again, I've been scouring various Atari related sites recently and noticed a distinctly non-commercial attitude in many hardware projects.
You'd almost think some of these people were designing upgrades for the love of the platform or something.
Unlike those poor Atari savages, we've had companies like Phase 5, GVP, DCE, Elbox developing our hardware. But then, when most of those companies disappear cos there's no profit left in this market we have no homebrew hardware scene to take up the slack, and our maxed out A1200Ts are outperformed by Falcon 060s...
God knows making an accelerator card isn't remotely easy, but it's a lot easier now than it used to be, and we seem to have a lot more hardcore solder junkies around than we used to.
I'm not gonna start a campaign to get a new card out on the market or anything, but maybe the cynics could back off a little bit so the people with the know-how aren't so scared to come forward and make their contribution.
I know it's hard to stay calm when someone posts dodgy info or uninformed opinion, but this is just a discussion on a web forum. It's not life or death.
I wonder what that Rodolphe Czuba guy has been doing for the last year.
After all that hard work on the Phenix, it must've been heartbreaking to be let down by others so late in the development.
Take his 060 card, SDRAM interface, PCI bridge, and marry it to the basic 'magic-happy-chips' that every A1200 accelerator has (I don't know much about that stuff...) and you'd have an ultimate 1200 upgrade that I'd be happy with, even if it cost £200 for a board without CPU or any other socketed components.
-
1) An IO mapped eprom is hardly the same as a multi-master tristate bus but hey...
Nobody said a ROM is the same as a bus, or that it is IO mapped, the point is that it can co-exist.
2) The x86 Northbridge (or is that southbridge?) has like 2,000,000 gates or more to convert between buses and standards. Obviously I am not saying you would need even a fraction of those gates, but it is not going to be a sunday afternoons work.
I agree that it's not likely to happen, in an afternoon or otherwise. So maybe it's a pointless argument, but I disagree with your characterization that using some other CPU is substantially more complicated than existing accelerators. Dunno about the Duron, but I've looked at the socket 7 pinout before and the majority of pins are for power, debugging, and multiprocessor systems. The stuff that is relevant to interfacing the CPU to an Amiga bus is not really exotic.
-
I consider myself a total beginner at electronics. I've, however managed to get myself acquainted with the subject, so that I have a glimpse what electronics is all about. Having followed the development of great homebrew Amiga projects on this forum and others (i.e. Dennis' MiniMig), I've got an itch to get my hands dirty in a project. Although it's starting to seem that I'm way over my head with this project. But hey, you can't blaim a guy for trying. :-D
Obviously, I would get easier and probably cheaper off if just bought an accelerator second hand. Of course, when I came up with this idea, the first thing was to try to find out whether similar homebrew projects exist already. The lack of such projects made me to bring this subject up on this forum. Having followed this thread, I've let myself understand that there isn't a modern chip available that would be downwards compatible with the MC680x0 family of chips. PPC is one thing but I suppose that is more viable if you want to use OS4.
-
Today would be quite easy and cheap make accelerator card for a1200 with 040, even as a hobbyist project.
manufacturin costs would be aroud 40 -60 €
Just wonderind why allways this kind of treads start to go to distant galaxy ???
Allways starting to imagine 10 000 € accelrator wich would be impossile to do with just hobbyists or semi pros and planning would take 5 years.
Another point is, that seems ? that coldfire accelerator is pointless, would be too slow with old apps and any "not so system friendly" programs wouldn't work
-
Sorry about not posting when I got home, I got errors on the a.org site when I went to post (Just one line of text something like "reply can not be posted"), mehh.
The 68060 SD-Ram chip was made by Vcubed and was/is called the V380SDC, supports 2gig of SD-Ram, an i2c interface needed for DIMM modules (Well not needed but a standard part of) and designed for the 68040+, PPC's and others.
The company sold over 10,000 of this chip in a year (Probably rather low but getting it wasnt easy from what I saw)
The down side is Vcubed went bankrupt, the IP was bought by Quicklogic and the new company no longer seem to make the SDRam chip (Only PCI bridges from Vcubed) but they are still available on the net, just may not be wise to do a new design using them.
Linky to news item (http://www.thefreelibrary.com/V3+Semiconductor+Introduces+New+SDRAM+Controller-a055172792)
Datasheet for chip (http://www.datasheetarchive.com/search.php?q=V380SDC-75LP%20REV%20A0)
-
Interesting.
I found the Datasheet on the net, there is no real details about the interface timing. I suspect that it is not as good as Rodolphe's CT060 SDC. He went out of his way to maximise SDRAM performance for a 100MHz 060, taking advantage of any and all burst modes of the 060 processor.
The datasheet is also available here (http://www.digchip.com/datasheets/parts/datasheet/392/V380SDC.php
)
If the part is still available through the reseller network it could reduce the cost of a 68060 turbo card considerably. A large gate FPGA could be replaced with a low gate count CPLD.

As we haven't seen one out in the wild having the opportunity to test/benchmark one it is hard to judge...
Unlike those poor Atari savages, we've had companies like Phase 5, GVP, DCE, Elbox developing our hardware.
Unlike those poor Atari savages who run TOS on a Freescale Coldfire developer board. we are discssing if AMIGA OS could be run on Coldfire. I have to admit that the Atari OS seems to be somehow open sourced so that a re compile is possible...

Actually, TOS isn't opensource. The MultiTOS kernel (known as MiNT or FreeMiNT) is, however. Didier M has managed to patch and reverse engineer the binary TOS ROM image by hand, which is.. well.. insane. But that's what he did.
AFAIK someone else has had the FreeMiNT kernel up and running on some coldfire evaluation board.. Opensource is great.

Nope, that's the guy. He's developing graphics drivers for CTPCI, the PCI adapter for the CT60. Since no actual hardware was available, he started patching TOS instead, and used a freescale EVB.
