The +5v SB is the violet wire and is pin 9 on the cable. (second from end of cable). Pin 8 is gray and is a 'power OK' signal. Pin 7 is black and is ground. Diagram below is correct.

I must have a different version... Here's my pin layout:
Row 1: Yel | Prpl | Gry | Blk | Red | Blk | Red | Blk | Orng | Orng
Row 2: Red | Red | Whit | Blk | Blk | Blk | Grn | Blk | Blue | Orng

Right next to the purple wire is the black common. I did get the link to the power supply. The ATX 200 is the most common power supply. I keep a diagram of it.

I tried to include a link to a picture of the power supply but I guess that's not allowed in newsgroups.
The PS actually has a diagram of the pins. The purple is the +5vSB. The label indicates black
is Common, but there are several black wires. Any idea how to determine which black is common?

Most supplies are printed with +5vSB. (Standby). I searched Google for 'pc power supply diagrams'. There are more than one of course so you might try searching for your model. I print out the diagram and it helps tremendously in fixing them.
I hesitate discussing them because so many people believe you can electrocute yourself if you open the supply.

Would that be on the two pegs that the switch connects to... or where would I check?

Can you check to see if you have +5v? If not, the supply is dead.

I took the cover off the power supply, the fuse is ok.
I appreciate you hanging with me on this but it looks like we're at a dead end.

Sorry I never checked the type of switch as to whether it was momentary or push on and push off. Since the power supplies are 'switch mode' a latch type is not needed, (the power supply only needs a start pulse). But, the design engineer may have something else in mind to accommodate sleep, hibernation and forcing power off functions.
With the computer plugged in there should be a +5v standby available. This is a fused line but buried within the supply and is available on the power supply cable..

I have removed, reseated, etc. I even cut the two wires (previously) and did a direct short.
I have removed the plug from the motherboard, shorted the two pegs where the switch
connects. The cutting of the two wires was done about 6 months ago, resoldered of course,
and it has worked since that time. Today I did the shorting of the two pegs on the MB.
Should there be any voltage present on these two pegs?
I would suspect the switch is a push/on, push/off type switch, where pushing for ON would
maintain contact within the switch.

Something simple such as a bad power on switch or the cable from the power on switch to the board. Most all PC's have a cable from the power on switch to the mother board. This provides a signal to the power supply to start. If you can, reseat the cable.

No additions at all. After replacing the power supply, it became intermittent, or rather continued
to be intermittent. In other words, replacing the power supply did not seem to fix the problem.
About 6 months ago, I could not get it to start, so left it alone. Four days ago, tried again, and
it booted, ran ok for 2 days. Now back to not booting again. Again, no sound, no lights, no fans,
nothing.

Why are you guessing it is not the power supply if you replaced it and it worked? Has there been many additions to the computer that is loading the power supply more than its rated capacity?

I know this is not the correct newsgroup, but with the big knowledge base here,
hope somebody can help...
This PC would not boot, no lights, no fan... nothing. I replaced the power supply.
It ran for a couple days... now dead again. I'm guessing it was not a bad power supply,
perhaps bad motherboard. I'm looking for somebody with one of these machines that
might be laying around collecting dust and may want to let go of the motherboard at
a reasonable price.
