A1200 with 4mb Trapdoor expansion

FAST RAM will actually double the usable speed of the A1200.  CHIP RAM access is very slow compared to FAST RAM.  I agree that an accellerator is a better choice but some FAST RAM and a FPU go a long way.

Agreed.  An app that runs fine on 4MB of FAST RAM will run the same on 8MB or 128MB.  But, we're talking the difference between CHIP and FAST.  Like I said (I think) CHIP RAM access is horribly slow.

A simple RAM card shouldn't take much power, so the standard black power brick should work.  Only way to find out is try.  If that fails, then try an A500 power supply.  They're easy to find and have a bit more juice.

As for the RAM speeds, the chips are actually 80ns or so.  But, as I recall everything goes through the Alice so this slows everything up.
