( This may be a repeat, but I didn't see it on the net ) I have several of these tape machines but very little time to work on them. I would like to give one away in exchange for a working interface. I propose the deal to be : You send me $40 I send you the stuff listed below You send me working software + cable diagrams I send you $40 Ongoing discussions as to functionality, problem solving would be expected. etc. Anyone interested? Anybody want just a drive? --------------------------------------------------------------- Archive Sidewinder 9045 Streaming Cartridge Tape Drive - standard 1/4" tape cartridge - 20 megabytes formatted per tape - up to 90kbytes/sec transfer rate - brand new units without cases ( OEM models ) - approximately 4.6"x 8.7"x14" - requires +24V @ 0.8 amp and +5V @ 4.5amps - hardware interfacing is via : .______. .____________ | | online | | | |-----------> | | | | request | | | |-----------> | | | | ready | | | |<---------- | | | | exception | | | |<---------- | tape | | host | | drive | | |<==========> | | | | 8bit databus | | | |<==========> | | | | | | | | xfer | | | |-----------> | | | | ack | | | |<---------- | | | | dirc | | | |<---------- | | | | reset | | | |-----------> | | |______| |___________| - software interfacing is via an intelligent controller which accepts commands like : o reset o read status o retension tape o erase tape o write o read - documentation includes : o product discription o operational specs o controller operation o host interface description and design guide o flow charts and timing diagrams o theory of operation manual o maintenance manual o trouble shooting o complete schematics o update notes from Archive -- ___________________________________________ |---|---|line--upon--line---|---|---|---|---| watmath!watcgl!electro!george |---|--building the foundations-|---|---|---|---| george@electro.com
