(you know how that goes) We just had a Southern Cal. Apollo Users group meeitng and the topic was tapes and drives. Jim Ward spoke first, his product is a replacement for RBAK/WBAK, that is true distributed computing (as opposed to just distributed data). Rather than the node with the tape drive *asking* for the files from other nodes to be sent to it, it starts up processes on the other nodes so that *they send* the files. In this method, the tape drive never stops and starts. It's quite a time saver. Next, a rep. from megatape showed off their drive. I think it was 800 Meg per tape. Then our own Steve Cooper showed off our AT bus to Pertec Tape Drive controller board. The pizza was horrible as always, but have you ever seen a programmer turn down even bad pizza ? The muffins were a nice change. >UUCP: {uunet, ihnp4!umn-cs}!hi-csc!giebelhaus Richard @ Danford -- Richard J.
