OT: Language for the ages

I suspect the original mention of 11/44 was done for a reason. The PDP11/44 poser supply is very complicated inside, it's really 3 separate SMPSUs running off the stame 400V DC supply (rectified mains), with a board of control logic at one end to do things like turn off the CPU and Unibus power, but beep the memory alive. Oh yes, there's an optional battery backup unit for the memory supplies. And even a full-H driver for the special cooling fans (and that is also supplied by the battery unit if fitted). However, DEC schematics are pretty clear, and there's nothing that odd in the PSU. I think I could keep one going, and repair it in less time than it would take to bodge in some modern, less well made and less well documented replacement. However, if you're the sort of peron who'd afraid of coke-can sized capacitors charged to 200V, then there's noting that odd about the outputs of the 11/44 PSU,. There's a 5V rail (120A or so) for the logic and +/-15V rails for the Unibus slots. Another +5V and +/-12V rails for the memory (there's no good reason why the 2 5V rials couldn't be linked if you're not keeping the battery backup). Maybe a -5V. You'd lose the battery backup ability, you'd lose the ability to power down the CPU and Unibus but keep the memory on, and you'd better change the fans for something more convenitonal (12V DC would be the obvious choice). But yes, you could bodge in another PSU without too much hassle. -tony
