Heeeeellllou all! So I'm going to be playing around with a 7933 disk drive during the weekend and I'd really appreciate some help. The 7933 is a big honkin' washing machine sized hard disk circa <1985 with a nice keypad and a nifty display (it's not seven segment, more likely ten-segment or something like that). The procedure for powering it up is something like this: connect power (normal single-phase 230V), hit circuit breaker, wait, hit "load/unload" button, wait 3 minutes for the disk to spin up, wait 4 minutes for airpurge (I gather this was simply "purge" in previous models, much to the delight of MPE users) and if you're lucky you'll get "drive #" on the display. So this much I know, but I was wondering if anyone has even a short list of the keypad commands (test numbers etc.) I think it has bad blocks and before I try mediainit I might as well run the built-in diags. TIA, -- jht
