A3000 <-> A4000

Sorry, need to reword this. I know that the A3000 and A4000 share the same CPU slot (save for one missing connection required for the CSMKIII/PPC SCSI controller).  I've used both, and have swapped several accelerators between both.  It's just that an A3000 running with the default 030 configuration usually has it's CPU on the motherboard so there is no daughterboard that can be swapped out.

Mendark will need to get another daughterboard for his A4000.  After hearing horror stories with trying to fit A3640's in A3000D's, I would recommend that Mendark try and get his hand on another accelerator board for his A3000.  Possibly with the money he gets from selling his A4000.

I should have read that more carefully!

Hmmm.. First of all is the A3k a 25 or a 16 mhz.
If its a 25mhz then don't bother with the A3640.
My A3k is a 25mhz and I added the A3640 card.
The A3640 runs at 25mhz. There is a little gain
from the card but not that much to bother with.
As for the 16mhz machine, the A3640 card helps
quite a bit. The a3640 card in a 16mhz is worth
while.
I glued a large HeatSink to the 040 chip and mine
hasn't given me any trouble. Its stable.

And when installing the A3640 card in an A3k,
first make sure its the correct version, and
the correct roms and get the correct jumper
settings.
The A3640 card won't work with Version 37 roms.
Its best with 3.1 roms.
Blow the dust out of the machine and clean the
fan in the power supply.
