>BTW, Ken, are you using the ORIGINAL PALs from the 5MHz 8087 board?

Yes, I am.  I'm using the UCI 8 Mhz speed upgrade, and the only other
things that I changed on the machine were the RAM PALs (for 256k
DRAMS), the DRAMS themselves, and the processors.  The only
peculiarity which I've run into is that CP/M (85 and 86) won't access
the hard drives at 8 Mhz, but MS-DOS (3.1) is fine - must be timing
problems in CP/M, IMHO.
