I'm looking to speed up my poor 4.77 MHz 2088 as cheaply as possible.
My current plans are to install a 9 or 12 MHz V20 CPU and the fastest
crystal I can get away with. According to an old Byte I have lying around,
I should be able to get at least 6 MHz without problems, possibly 8 MHz,
(although after 6 they say it depends on the individual machine) and that
after that I can probably expect to crash the machine. They also mention
that a timing chip (the number escapes me at the moment) has to be
replaced.
Has anybody done this? Just how fast can I drive this board before I
cause timing problems? (I can always install faster memory, but if the
timing of the board logic is the limiting factor, that sets my upper limit
on speed, not the memory speed) Does the Amiga side require the board to
run at a certain speed? (or a multiple of a certain speed?) Is this timing
chip on the board? Is it socketed? Is it worth it?
Incidently, why are half of the RAM chips on the BB socketed, and half
unsocketed? Can the socketed RAMs be replaced with something bigger
?
