I ran into an interesting problem. Eric Smith's copytape program assumes two tape marks in a row is logical end of tape and stops reading. I've had problems with this before with MPE store tapes, because they put two file marks at the start of tape so I just keep reading until I get 10 errors in

Most all 8 inch drives were synchronous capacitive phased AC motors. That is until 3 phase low voltage motors started showing up on 5.25 disk drives. The ac motors on the 8 inch drives rarely had jumper options for 120/240V AC. Most were fixed voltage and cycles. I can't recall any that I've

Hi Jos, Thanks very much for posting about the NinjaFlex material. That will come in very handy as my students design robotic parts, although I'm sure it won't be long before custom-made "rubber" bands will be flying around the lab, and new-fangled slingshots ("wrist rockets") won't be far

Hi Glen Sorry for not replying right away. I've been on the road. No, I've not gotten the manual. I do have a disk controller board with my system. I'd have to look back to see what disk controller code was in the ROMs. I suspect it might just be to read the first bock of data and then expect
