I read from a dataloggin recorder that drops 32K blocks on me every tenth of a second (and can't reposition so I have to pick them up) and write them to a Storage Tek 6250 tapdrive (I hate Digidata). Multibus II is fun for this type of application. The use of the Ciprico tape controller makes life fun because I can just throw the received 32K blocks at it and let it run the tapedrive. Unlike a normal UNIX device driver the Ciprico has no queue of I/O's in the driver. You just keep chucking the MBII messages at it and it will send you back the answers when it is done. -Ron
