ACA 2000 interest?
« on: November 19, 2014, 03:00:46 PM »
Would I be the only one interested in a 'ACA 2000' similar to 'ACA 1233 40Mhz Accelerator with 128MB RAM', as my a2630 cannot be upgraded (other than rare dkb mem)?

A2000 are at least common, if not the most sought after.  Just a thought.

The ACA2000 happens to be in development allthough not too much progress is shown. But it's probably better to show a product when it's finished. I would also like to have an ACA2000.

I'm interested as well, even if it has 020 and some ram.

I'd be interested in that as well, but only if it has a minimum of an 68030@25mhz.
Systems:
A500 (Originally purchased new 1989) - 3.1 ROM, 2meg Chip, 68k cpu
A500+ 3.1 ROM, 2meg Chip, 8meg Fast, 68EC020 @ 28mhz, CF Slot, SD Slot. (Classic 520 accelerator board)

The RAM would be the biggest selling point, since for most people using GVP-brand accelerators in their A2000's, know how hard it is to find compatible RAM.  IMHO I wouldn't be interested unless it was at least 68040 speed and instruction-set compatible, MMU, and SCSI.  In other words, I'd prefer a 33MHz 68040 over a 400MHz 68000.  But I am probably not the target market for this board.  ;)  Would be good for unaccelerated A2000 owners however, and breathe new life into all of them that keep popping up on ebay.

These really are the unloved ones but you can find them dirt cheap. Sturdy and reliable ECS machines though.

I wish someone would finally make upgrades for the big box Amigas.

In the US, big boxes seem more common than A500/600/1200 are. I was giving them away by the stack for a while.

I think ACA500 could be adopted to A2000. The A500 expansion slot is almost the same as ZORRO slot on A2000.
I'm not sure if A2000 can take accelerator cards on ZORRO slots, because that is what the CPU slot is for. It's possible that some signals are not present in ZORRO slot that are on A500 exp slot. I would have to check the schematics.

Something to think about...
A500 KS 2.1, 1MB Chip, 68000
A600 KS 3.1, 2MB Chip, ACA630 32MB RAM
A1000 KS 1.3, 8MB RAM
A1200 KS 3.1, Blizzard IV 50MHz 64MB RAM
A2000 KS 2.1, 68030 25MHz, 6MB RAM
A3000 KS 3.1, 68030 25MHz, 16MB RAM
A4000 KS 3.0, 68040 25MHz, 16MB RAM
CDTV KS 3.1, 4MB RAM

Imagine an A2000 with this hypothetical "ACA 2000", and a BPPC / BVision.  I know it's been done on A500's.  Of course then it will just drive the price of these old accelerators even higher.  Ya just can't win!  ;)

I wouldn't be interested in it if it didn't use the CPU slot.
Systems:

I would be interested IF it used the CPU slot, and the '040 running at least 40MHz, w/128Mb RAM. I really miss my '040 PPS card.....
A2000 GVP 40MHz \'030, 21Mb RAM SD/FF, 2 floppies, internal CD-ROM drive, micromys v3 w/laser mouse
A1000 Microbotics Starboard II w/2Mb 1080, & external floppy (AIRdrive)

Seems to be some direct info from Jens here on this thread, as well as links. ACA 1000 that adds 2MB of chip mem? Hadn't heard of that one! ;)

I loved my Tekmagic 2060/128Mb ram til it died. Now back on the old GVP 030/40 combo. Would really like to see a big step up!

I made a comparison spreadsheet and compared the ZORRO-A500-CPUslot.
Looks like A500 exp slot is about 90% same to the A2000 CPU slot, only 6pins are not matching, all other are pin for pin the same.
So A500 exp conn IS A2000 CPU slot.
A500 KS 2.1, 1MB Chip, 68000
A600 KS 3.1, 2MB Chip, ACA630 32MB RAM

A1200 KS 3.1, Blizzard IV 50MHz 64MB RAM
A2000 KS 2.1, 68030 25MHz, 6MB RAM
A3000 KS 3.1, 68030 25MHz, 16MB RAM
A4000 KS 3.0, 68040 25MHz, 16MB RAM
CDTV KS 3.1, 4MB RAM

Hey Chris!

I sold one of my 2 TekMagic 2060 accelerators a couple of years ago, but still have one of them installed in my trusty A2000 with the modified Agnus chip for 2mb of Chip RAM.  If you really want a 68060 accelerator for your A2000, you might be able to talk me into selling it.  I doubt I would sell it to anyone else right now though, but since you are a close friend..........?

I have lots of fond memories from when I was using my A2000.  I spent a small fortune on that Amiga and probably spent more time per day on that system than any other Amiga (probably any computer period).  I once used all of a $3,000 zero interest loan from work for computer gear & software, plus some of my own money on that A2000, on a single order from Creative Computers in Santa Monica, Calif.  I purchased an IVS Vector 2000 68030@25MHz accelerator w/SCSI & 32mb Fast RAM, Vortex Golden Gate 386sx Bridgeboard w/16mb RAM, DCTV display enhancer/slow scan digitizer, PicassoII video card, AdPro2.0 graphics conversion & effects software, and a few other items I can't remember were on that order.  Luckily the people at work who were responsible for checking to see that the zero interest loans were only used for hardware & software that was compatible with the software being run at work weren't looking too closely, or did not know what they were looking at, so the loan was approved and I got to buy all those goodies at the same time.  It was like Christmas in July for me that year!

As for interest in an ACA2000, I would want to see what happens first with the "Apollo" FPGA accelerators that are supposed to run at speeds equal to a Morotola 68000 clocked at 400MHz or more.  I had read that the Apollo Team is proposing accelerators that will fit inside almost all Amiga models, but I think their first model is aimed at the A500, CDTV, and will also work inside of an A2000, and possibly an A1000 with a riser adapter, which all use the same socket for the original Motorola 68000 chip.  Not sure if they are going to go through the trouble and extra expense to design an Apollo accelerator that fits into the A2000 accelerator slot, if the one for the A500 & CDTV fits and works in the A2000?

I do like the ACA accelerators and believe that Jens of Individual Computer's makes superior hardware projects (usually) as a general rule.  It would be nice if all of the Amiga hardware designers could share some of their work and code, so all FPGA projects could take advantage of the newest and fastest 680x0 Soft-Core's being worked on by a handful of programmers.  But then the guys doing most of the work should get some kind of licensing royalties from that code, to pay them back for their time spent writing and testing it.

@OldsmobileMike,  I am sure that the 68000 Soft-Core that is reported to run at 400MHz or more already has some of the 68020 instructions integrated, or will have some, or most of the 68020 instructions implemented in the near future.  That is the great thing about FPGA Soft-Core CPU's, is that the programmers writing them can enhance them with extra instructions, or improved instructions.  I don't know if we will ever see 680x0 Soft-Core CPU's that include all of the 68040 and/or 68060 instruction sets, but perhaps the programmers working on these Soft-Core designs will be able to add the most used and needed instructions, so that 90% of the software optimized for 68040 and 68060 CPU's will be able to run on these FPGA accelerators and stand alone systems using Soft-Core CPU's.

Minimum: 030/40 mhz + 128mb

In a perfect world: 040-060 with ACA2000 stripped to just be only an adapter(+CF?) to lower cost.
