RE: Unrecognized DEC Power Supply in PDP-11/44 Configuration

Josh & Pete: Thank you for the identification. Don't think that the unidentified quad-boards constitute a SMD controller. I guess the SMD controller was in the second chassis and went wherever the HDD went. Strange that the PS didn't go with it. I can feel a bit better for not having

Ugggh, as soon as I saw this conversation I new it was going to be a race to the bottom. Actually, it was far less worse than I expected, so progress, perhaps? I've been frustrated by the lack of women in the industry, because there's no rational reason for it and it feels like we're wasting

Disk cartridge storage racks

I am in need of some disk cartridge storage racks. The kinds I am looking for are the ones used for front-loading cartridges (IBM 2315, DEC RK05, etc.) as well as the ones for top-loading cartridges (IBM 5440, DEC RL02, etc.). They were typically made of welded wire, and stored the cartridges
