I'm preparing my Apple II Rev 0 and related documentation for sale soon, as mentioned in a earlier post on this forum. I last powered it on successfully in September 2014 and let it run a few days, with on/off cycling every so often. Turned it off, backed away in its Apple carrying case and put it on a shelf.
I'm the original owner, purchased it in late 1978 all with its original PSU and chips, Serial # A2S1-3465, PSU A2M001-3615 (toggle switch), and used it extensively for generating vector graphics used in professional laser shows. I graduated to the IIe around 83-84. It has been periodically turned on (booted) to maintain its health. I have to admit that I was surprised that it powered up to all the correct Hex mode, FP Basic prompts in 2014 since it was last turned on and exercised about 8 years earlier.
I've been taking photographs of it and its accessories for the Ebay posting. When it came time to take current photos of operational display screens...it would not turn on. The PSU was totally dead. I had purchased a full set of replacement caps for this eventuality a few years ago and intend to repair the PSU. In the meantime I'll use a spare IIe PSU to make sure the MB is still viable. It has the FP ROM card all the original cassette tapes and more.
I've read many Rev 0 and PSU post on this forum over the years and noticed a lot a questions about whether there were Rev 0 PSU schematics and component lists, etc. The Rev 0 PSU schematic in the Apple II Reference Manual appears to represent one of the earliest incarnations and is not accurate for my Apple II and PSU serial numbers. The bottom of the PSU PCB is "PWR SUP 4A", so it is probably a 4th generation to what is shown in the Reference Manual.
So I've taken extensive photographs of my PSU and its components, including the single sided PCB and created a component list.
Thought I would first see whether there is any interest in my posting furthing information before continuing (because maybe its already on the forum and I've just not seen it).
