These are good signs. But we still haven't really established which model of Mac you have, and at this level it matters a great deal: The earliest Macs (eg. 512K) support only a 400K disk format and require very early System versions, up to 4.2. Slightly later models (eg. Plus) support the 800K disk format and System 6.0.x. That's why we've been asking you to look at the model number on the back panel, which is more likely to correspond to the real hardware inside than the artwork on the front panel. - Jonathan Morton -- -- ----- You received this message because you are a member of the Vintage Macs group.
