@hppacito

I already had read this whole thread and saw how it came about. I actually didn't want a Coldfire anyway because I knew it would have software compatibility problems (and saw Oli's project fail). I mainly wanted something faster than 33Mhz and more than 8Mb RAM. Actually, I was hoping for something like the mysterious and elusive Viper 530.

I wish you luck on your project, though. :-)

Just a quick question. How do you plan on getting the ethernet connection out of the case? As there is not a ready made 'hole' in the 5/600 case.  :-?
A1200 (Dead :-(  OS 3.1/3.1, 030@33, 882@33, 2/8MB RAM, 1.4GB HDD

@hppacito:

In the A500 case, you could always go for an internal connector on the accelerator for one of those CF or PCMCIA wireless 802.11b nics. That way you wouldnt have to drill or cut in the case to get connectivity.

I bet the already existing orinoco/prism2 chipset driver for the A600/A1200 PCMCIA port wouldnt need much modification to function with a orinoco/prism2 based card in a socket on your accelerator. That would also save you the work of writing a completely new driver for the ethernet chip.

@mr_500;

Would be neat to have a 040 or 060 in there... but I think that the price of the processor alone drives everything a bit too far. At amigakit they weight 50 pounds sterling (70-80 euro) and new even more !

I don't see a clear path there. But, what yould be really really neat:

An A600 case with:

VGA Port, Audio port, USB, Eth.
Slim cdrom
Internl 2,5" hd
Emulated AGA or ECS chipset, in hardware (No idea if is or not possible), but with what people do nowadays with fpgas looks quite tempting (looks like too many timing problems).
Amigaone board, or similar. (I think minitower cases or bigger ones are too cumbersome)

Probably is just a wet dream of me.  :-D

The eth connection will be left to the installer:

1. Make a nice hole in the case
2. screw the little board with the connector
3. enjoy ?  :-D  :-D

@patrik:

That's actually a very good idea. But a full PCMCIA port should be available then.

There are many ideas floating, the thing is to find where the parts are available and how much they cost. A PCMCIA port can be used for many things, especially if has external access, but the connector is somthing to consider. A cheap onboard eth solution costs the same money. Unless the board is well screwed to  the case or so, I would not insert anything in a PCMCIA slot. That can be explored in a second revision.

btw:

Oxford semiconductors has a really nice USB host controller, the TD242LP, but the reseller they give is a bit less than helpful in its web version. Anybody know another good alternative, how much they cost and where can be bought in small qtys ?

Thanks !

How's the accelerator coming?  It's been a week already and now your project is competing with the PowerVixxen LT, Dragon, Troika for my dollar :)....just kidding.  No, but seriously, any news?

News ?, some.

I'm working on the CPLD. I got a so-so deal for the RTL8019AS, and I just happened to order 2 of them for the protos. The rest of the components are alredeady bought. So I expect a board soon (I still have to draw it !).

Still didn't find a 2,5" Harddisk connector. I think will have to be a 3,5" haddisk connector. Is a pity the only electronics shop in town is a bit weak in I.Cs, and connectors... But hey, this is (KAOS) germany, I should be able to get anything !

So far, no luck with usb host controllers. So no USB for the time being. I think that may be USB can be done completely offchip, I mean a uC with host USB capabilities, and working as a full USB host, with stack and everything. That will off-load a lot from the 020. I wonder if that can be achieved.  Maybe someone can step in. Maybe a limited set of peripherials, mass-storage, and HID... maybe just a wet-dream :crazy:

The powervixxen looks really sweet. I hope for that price comes to reality. A pity freescale doesn't make a cheap 060... they have the tech... even at 40 or 50 MHz, that would rock !

I am in for two, one for A600 and one for A500.  I would like a 2.5" IDE port if possible but I guess a 3.5" is ok as you can still install a 2.5" HD correct?  Is the A600 version also going to have a IDE port?  I imagine No.

what is your plan? Are you going to create two seperate boards? One for the 500 and one for the 600?

Wouldn't it be easier to just include an A1200 compatible clockport header. That way, users can just add a Subway card if they want USB. (Plus the board will be cheaper for those that don't want it).

 BTW, last time I checked, RS Components stocked 2mm IDC headers, also the Jelu Web Shop has right angled 44 pin headers for 1.21 euros.
On schedule, and suing

If I may...?  I think you really, really should go for the onboard USB.  It'll open some expansion options up for A500/600 users that they might not have had otherwise - I mean there's always folks asking "How do I get xyz files from my Amiga to my PC..." well a cheap USB/ethernet dongle would be at least as fast if not faster than a serial connection, wouldn't it?

Plus: mice, keyboards, external storage (mmm...an A500 with a sweet external CD-RW or even plain-jane CD-ROM or HD), other input devices, etc.

Consider it.  Please.

Did you miss my suggestion about making a 030 or 040 socket available for those who can shop for their own chip or who might extra chips lying about? (Plenty of dead accels out there) I already have 030 accels for my 500 and 1200, so I won't be interested in an 020, but I'll be rooting for you anyway. I'll be following to see what your future projects might bring.

firstup hppacito, Kudos to you for having a go!

Ive had a crack at designing my own PCB's before.  Its not as hard as a lot of people think.  

The most complex was a a Cvid->RGB converter, I found a few complete products on the net for ridiculous prices ( AU$300-600), in the end I got the parts together, translated the schematic from an existing product onto PCB and built my own.  
All up, it cost less than AU$50 and took maybe 3 days and a couple of tries getting the PCB right.  Its been working fine driving a RGB-only LCD for about 2 years!

The hardest part was getting some rare parts and building my own RF chokes.

Good luck, keep having fun & dont listen to the naysayers!!!

That's an idea. I've have a lot of old Apple cpu's lying here 040 and 030.
