The IIci uses part of Bank A for video memory when you have a monitor connected to the onboard connector. Whenever data is transferred to or from the video buffer, the CPU is locked out of the rest of Bank A.
That happens very quickly, but if you install a fast NuBus videocard, the computer gets a bit of a RAM performance boost. The IIsi is the same way, but fortunately Bank A in it is the non-expandable 1 meg soldered to the board. For the IIsi, there's a "RAM Muncher INIT" that fills up all of Bank A not in use by the video buffer. That way, there's nothing for the CPU to access in Bank A. There's not a RAM Muncher for the IIci, and if there was, you'd only want to use 256K SIMMs in Bank A. --- John Niven <[EMAIL PROTECTED]> wrote: > Gregg, > > can you elaborate on this?
