I recently bought an old (1988) Creative Microsystems Inc. 14MHz processor
accelerator for my Rev 5 A500, and installed a 68881 chip into the socket
available. It works fine at 7MHz, no acceleration both with and without
the 68881 enabled, it also appears to software toggle to 14MHz. However
when at 14MHz it will allow me to close, fronttoback etc the windows that
are open but dies upon doubleclicking an icon, or typing to a console
window. It either hangs, (ie. stops reading mouse, keyboard) or gurus
with a typical guru number B. Using NoFastMem seems to slows down the
speed at which the guru happens but does not stop it.
A more serious problem is that the system will not boot when my A590 hard
disk with 2Meg ram is plugged in, upon powerup the screen goes white and the
power light flashes. With no floppy in the drive (I have 1.2 ROM's) the
workbench prompt never appears.
Adding or removing A501 trapdoor memory expansion has no effect.
Any help would be appreciated, including the current address/phone/email
of CMI as the ones that came with the product no longer work. (or info
that the company no longer exists)
Thanks Daryl Scora
