"SFTW P/N # 98-P39972M " "SOFTWARE VER # 8 " "SOFTWARE REV # 4 " "SOFTWARE DATE 13 JUL 1995" A 68000 seems like a good choice to me. It's probably overkill, but that's a whole lot better than running out of CPU and/or the bugs associated with trying to squeeze software that doesn't quite fit. If I had working code, I probably wouldn't rock to boat to save a few pennies. How many of them did they ship? -- These are my opinions.
