Apple /// Power Supply

Actually I have a spare PSU, here in the UK, but sorry I'm keeping it for my own Apple ///s. These machines were so tightly engineered as regards FCC requirements that there always seemed to be a problem with getting the heat out and stopping the electronics shorting out against the case. Particularly the RAM daughter board at full capacity. The real time clock is a bit of a nightmare to get adjusted properly too. I don't mean to within spec, I mean to run so I don't have to adjust it every week, which is what I had to do with them when they were brand new. By contrast the 5MB or 10MB Profile hard drive sits in a box about five times bigger than is needed. It was a real luxury after doing the floppy shuffle for three quarters of an hour compiling Pascal programs, though upgrading to three floppy drives saved most of the arm work. Are logic diagrams available for the Apple /// now? If I remember right, even as dealers/service providers and hardware/software developers we were not allowed logic diagrams for the A///. That's where the rot started and we officially had to do module replacement, though we still replaced IC's when they had blown craters in the top of them, and were still able to buy AC power switches and such like Must drag them out from my brother's loft some time and see if either of them still work. Hope they're OK, they are stored above the cold water tank in their original boxes. Fortunately the loft is heated so should be OK. Roger Holmes.
