I have a DEC BA23 expansion chassis available to anyone who wants it. It has an 8-slot QBus backplane and power supply. I believe it to be working. To use it you'd need whatever cards were used to hook it to another backplane since I don't have those. It's one of the ones that doesn't have its own power switch, it powers up when you power up the main unit I believe. Oh, and it was rack-mounted. If anyone wants it I'll even deliver it anywhere in AZ (if you're patient). If you are really patient I could take it to southern CA next time I go that way. Gordon Zaft
