New User With Questions). I'm up and running. The internal 3 1/2 floppy drive was giving me trouble. The Commodore replacement drive is $100 +. The cheapest one I found was from a mail order place for $77. I went to a local "generic" dealer and got a run-of-the mill 720K drive ($58). Everything looked good, but when in the Workbench scenerio, removing a disk and inserting another would not be reflected in the icon. FIX: The Commodore interface looks for a signal "disk change" on pin 2. The drive was jumpered so that disk change (DC) appeared on pin 34 (READY). Pin 2 on other interfaces is used for density select. Sooooo....Jumpering pin 2 to pin 34 on the drive solved the problem. If anybody needs more detail, e-mail me. Here's my weekly question---What is REXX or AREXX?
