HPIB programming assistance

Hey guys, I am working on a project to breath life back into some old hardware. I order to do so, I need some documentation / assistance in writing low-level routines to talk to various HPIB devices. Specifically: I would like to talk to a HP 7978 tape drive, a CS80 compatible tape drive, or a common HPIB disk drive. I don't need help with HPIB protocol, I need to know the sequence of commands (sent across the bus) to move data into and out of those devices. I would expect to find this information in the programming manuals for those devices but so far, have been unable to locate the docs. If anyone can provide documentation for any of those devices or has experience programming them, I'd appreciate the assistance. Thanks, SteveRob _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com
