Lines: 15 In-reply-to: tgg@otter.hpl.hp.com's message of 28 May 91 08:01:48 GMT I remember proposing an automated tape mounting system at Burroughs which used a pneumatic "and" to select cartridges. The cartridge was to be blown out of the cell (better yet floated) and then gravity fed to a belt and then to a drive. Cartridge replacement was via xy Plotter means. This reduced access time, but would have been very hard on tapes. -- Blaine Gaither Amdahl Corporation 143 No. 2nd East St., Rexburg, Idaho 83440-1619 UUCP:{ames,decwrl,sun,uunet}!amdahl!tetons!bdg (208) 356-8915 INTERNET: bdg@tetons.idaho.amdahl.com
