Has anybody had experience with the Pacific Peripherals subsystem for
the A-500? I've seen it below $200 mail-order. The internal A500
boards are NOT cheap, even unpopulated, and you WILL need to get a new
power supply to power the critters. Not to mention that I see problems
with DMA SCSI controllers...

Seems to me that a Zorro II subsystem for the A500 is the way to go.
A2000 disk controllers and RAM cards are dirt cheap compared to their
A500 equivalent. Buying just a slap-on-the-side SCSI controller is
less expensive than buying a subsystem and an A-2000 SCSI controller,
but when you add up the cost of both the slap-on-the-side SCSI
controller and the internal expansion stuff... it's close, real close,
to the expansion chassis + A2000 cards alternative (especially if you
choose a SCSI controller with RAM on-board, such as, hmm, one of the
GVP Impact controllers).
