If you can't get into the hard drive you can't read the config.sys and autoexec.bat for clues, you can't run a diagnostics as easily. So it's just conservative, my approach. But yes you could just say this is a stock system I have the ref disks I don't see any need to worry. Sounds like you have worked on these enough to know and that's good enough for me. > > I'm assuming that said reference disk, ADF files, and possibly option > disk can be acquired. > > > The chances a model 80 will smoke out or catch fire is less enough > > to make that a secondary concern. > > Thank you for that. > > > no caps like that, this is an IBM. > > Cool. > > I didn't think so.
