I'm trying to narrow down my choices of what to search for on Ebay to replace a couple of my ancient Macs. I bought a Mac Plus in 89 and then a Performa 200 in 92 basically for one purpose, which was to run a program I have that controls automation on a studio recording console made back in those times. I still have the program (800kb floppy and a bunch of safety copies) and the console, although the Macs died a few years ago. I was running OS6 or 7 on those old Macs. Anyway.. I'm going to return to using the console and I really don't want to buy an eBay Mac Plus, or Performa, but would rather get something from that era that used a larger display compared to the teeny 9" b&w on the Plus/Performa. The program manual from my last 1994 upgrade of the software (before the software maker discontinued it) shows compatible Macs being Mac Plus..se..se30..II, IIcx, IIci, IIsi, LC, Classic, or Classic II. Performa was never on the list but worked fine as I think those were bascially Classics anyway. The software does not show an OS preference. What I'm sort of picking up from this list is that the software was basically designed for the 68030 based Macs. Anyone have a clue of what may happen if I try to run this on later 68040 or Powerpc based Macs that appeared later in time? This may be too vague of a question since you all don't know this software that I have. I figured I'd ask here before biting the bullet to just buy random old Macs to test.
