Here's a complete printset of the Venus Ibox, from 1984. It includes Ibox block diagrams, module and MCA block diagrams, and schematics for the MCAs and modules. I'd bet my bottom dollar that there were ECOs after this version. But this hardware ran VAX/VMS and oodles of software. Most of the page tops are faded. … Continue reading VAX 8600 (Venus) Ibox printset

Two 1988 papers on DEC culture
I worked with Steve Klosterman for a few years at DEC. He recently shared two 1988 papers written by Reesa Abrams. These may already exist in some online computing history museum.

Thoughts on DEC
I'm off this week, and while loafing around the house I took an hour or so to search the web about Digital Equipment Corporation (DEC), a former employer. That was a mistake, because it got me thinking about my past. This was fun for a while, and then it got sobering. I worked for DEC from February … Continue reading Thoughts on DEC
