Which 060 works best for A3000/T

Hello Folks,

I purchased an Amiga 3000T here on Amibay from quarkx a while back and have been trying to figure out since then which 060 card to buy that will actually work with the machine.

The system itself works flawlessly (thanks quarkx!!), however, I have tried 2 A3640 cards, one that was purchased with the machine and another borrowed from a local fellow Amiga 3000 user.

Both cards have been confirmed to function in my friends A3000, but, neither will work in my A3000T.

The system has a buster-11 and I installed a 74F08N in U103. I pretty much have the jumper settings for every CPU type committed to memory, yet, these did not work.

From what I have read in my research (which has actually been a lot of fun), the 3640 either works in the 3000, or it wont. This is ok, I am not married to this card. By the way, both 3640's tried were rev 3.2 and the INT-2 fix HAS NOT been done to the 3000T.

My actual question is: is there a sure bet accelerator for the A3000/T to look for that has an 060, on-board memory and on-board SCSI which will work?

Any help would be greatly appreciated.

Mike

Unless you want to go PPC then I would humbly suggest the BEST (not nessasarliy compatible with your A3KT) is the CyberStorm Mk3

With 128MB of 64bit Interleaved RAM (very fast!), Onboard FAST SCSI 3 (*upto 40MB a sec) and an onboard port for the Cybervsion PPC (not sure if this works on the CSMk3?)

Failing that then a Cyberstorm Mk2 is a fantastic purchase - again upto 128MB of FAST RAM, and an optional CyberSCSI Mk2 Module (*upto 10MB a sec)

Both fantastic 060 adapters, perhaps the creme' of the crop as the top end goes to be honest.

Cyberstorm MkII works only with 64mb on Amiga 3000 :(

umm Virge... why is that?

does that need a modification to the motherboard?

is that for the A3000D motherboard or the A3000T motherboard or both?

The Cyberstorm Mk I won't physically fit in an A3000D. The CSII will, but the SCSI kit won't. If you want the full works, as my esteemed colleague Zetr0 points out, the CSIII is the best '060 card in existence, and the CSPPC is of course the natural continuation of the CSIII.

If you want Accelerator SCSI, you'll need to do the INT_2 mod. (Google for it for more info, it's a fairly simple soldering job)

Amiga Resource has a list of cards that are allegedly supported in an A3000:

Probably worth a look. :thumbsup:

You're probably thinking of the Apollo 4060. That will only fit in an A3000 with only half the RAM slots filled.

Interesting, that's the first time I heard of a late rev. A3640 failing to work with an A3000T. This is very unusual since the A3000T was the only A3000 series machine C= offered with the A3640. In fact it was supplied with Ramsey rev. 7 and SuperDMAC rev. 4 which were supposed to improve compatibility with the A3640. Have you checked the +5 Volt supply on the motherboard or A3640? Are those standard 25 MHz A3640's or over-clocked A3640's? The clock jumpers should be set to EXT for a standard A3640 and I'm sure you tried that combination already. You might try reseating any socketed chips but I would also take a close look at the 200 pin CPU slot connector. The A3640 does not need the INT2 mod so we know that's not the problem here.

Obviously, these are some suggestions which might help until you can get an ultra fast Cyberstorm board or similar. I think the 64MB memory limit on the A3000 versions was due to physical space limitations which may not apply to the A3000T, but the WarpEngine and Apollo boards seem to have same limitation as well.

@Zetr0:
Thanks for that info my friend, I will keep my eyes open for an MKIII :-)

@SpeedGeek:
I know the borrowed 3640 was not tampered with in anyway. I don't know much about the one that quarkx included with the machine other than the fact that based on information gleaned from here and various other places on the internet, it appears to be a rev 3.2 board. I had discussed this with quarkx, and he indicated that he had never gotten around to testing the board before I purchased it from him.

It's important for me to stress here again, this 3000T works flawlessly with the on-board 030. Also, as I stated, it has a buster 11 and the DMAC and ramsey chips have been confirmed to be at the correct revisions. It also has 3.1 ROMS.

My concern is that I will purchase an MK3, or something of that nature, which is quite expensive, and it will not work on this machine.

Fortunately, I love playing with this machine, so, if there is something that I can do, or try, please let me know! :D I'm planning on pulling the motherboard this weekend to implement the INT2 fix, so, that would be a great time to look things over in relation to this problem.

The A3640 is a tricky beast to get to work with an A3000. Although, I'm astonished that your A3000T won't accept either, particularly if you've a DMAC-04 and RAMSEY-07 in there. The INT_2 mod shouldn't matter, that's only needed for SCSI. My A3000D doesn't have INT_2 and works fine with an A3640

I guess the concern would be that there's a fault on the CPU FAST slot. If this is the case, I can see why you'd be worried about shelling out for a top-end accelerator, only to find out your A3000T won't work with anything in the slot.

On the other hand, it should work with a CPU card, so in theory, it should be possible to repair it. And if there ever was a place full of enough awesome to help you do it, Amibay would be that place!

:thumbsup:

Did you set the jumpers right? Is there SC zips in the first ram bank(chip numbers ending in 402)? if so you will need some fast page ram in the first bank with the A3640.

Jumpers must be set properly in the 3000T to use the A3640 are you absolutely positive they were correct?

you added the 74f chip so you should be good there.

i have owned about 8 A3000T's in my lifetime and all of them with varying chips and motherboard revisions worked with the A3640 rev3.1 or newer

Int2 is not needed with the A3640.

The cyberstorm MK2,3,cyberstorm PPC and GVP4060DT( i have not tried the gvp) should all work in the 3000T

Int2 will be needed for boards with SCSI.

What roms are you using,you don't mention this? 3.1 are recommended
