Can someone at ATARI or elsewhere tell me _where_ the TT's fast RAM
is located in address space? How do you detect legally if fast RAM
is present? Currently, I intend to look for a _FRB cookie in the
cookie list; if it's there, the machine has fast RAM. But where is
it? Is the TT's memory mapped by the MMU so that it appears
contiguous? Don't tell me a legal program need not know about
fast RAM - I need this info for my hard disk driver which has to
decide if some transfer is to be made into fast or slow RAM. Tnx
for any help.
