Looking for a faster 040, currently have 040@25 (060 a possibility dependent on cost) for my A4000 desktop. Anything considered, memory & SCSI options would be good, let me know what you have :coffee:

Decided a 060 would be preferable, almost any 060 considered….

Still looking... unfortunately wasn't quick enough replying to Marmes offer :(
 
Maybe you would like to upgrade your cpu board from 040 to 060 by changing the CPU only and buy ZorroRAM. It could be much cheaper. I can help.
 
Already have a ZorroRAM card, I don't think you can upgrade a A3640..??
 
Next week I will meet with somebody who can do this. He need a MC68060 rev 6 and socket adapter (040->060). If we do that successfully I will report this fact here.
 
There's already a prototype adapter to convert 040-060, I've seen it used on a WarpEngine 040, I'd love one for mine! (060 @ 80mhz :eek:) I think the drivers are experimental though.

Personally I wouldn't bother upgrading the A3640, the memory interface is crippled enough already, you want a processor board with local Fast Ram.

I had an A3640 with Quad Doubler, 50mhz 040, it was fun for proof of concept, good MIPS bit in real use it was much slower than my WarpEngine 040/40mhz, 3D Games really suffered. (Yes I had ZorRam, in fact 2x 128mb)
