I'm doing a repair to a Sol20 computer. Some of them came with the "wrong" transformer installed. This results in the unregulated power on the S-100 bus being too high. 11 volts instead of 8, 22 volts instead of 16 (plus and minus).
Ahh, yes... That all makes perfect sense then.
You intrigued me since I'm really not familiar with the Sol-20, only recognize the name, so I went to look it up. I found it even more intriguing and was amused when I realized that Jim Battle had reasonably extensive info at
sol20.org. I have a functional multi-user Wang 2200 LVP system, and Jim has
the definitive Wang 2200 resource at
wang2200.org.
Great guy. I haven't conversed via e-mail for many years now but he went out of his way to provide me with some disk interface manuals, schematics and programming info that had not yet been posted to his site archive, allowing me to start to make an IDE disk interface for the ol' girl. (Well, technically I have two of 'em. I also have a 2200 MVP, which could be made into a separate working system with some kind of disk interface since I cannibalized the old 80MB CDC CMD "Phoenix" disk drive and suitcase controller decades ago.)
I simply haven't had time lately to pursue the project. Someday, eventually, though! With all the
(Real life and all, always interrupting, you know.)
Ah, yes. Yes it does. I have not pulled it apart yet, I'm at the parts collection phase. I had not even carefully read the instructions yet, just the parts list. On the plus side, with everyone's help, I located a place with a few in stock:

I guess I will go ahead and pull it apart to see what the crimp pins look like. I'm still looking for them. The vendor (above) does not have them listed.
That's great! It is amazing what the hive mind can come up with sometimes, isn't it?
I was hoping you at least had something to compare the pin type to. I expect it is a standard old-school Molex pin of one type or another. The assembly section talks about inserting the "open" side a certain direction and then inserting the pin until it locks. Certainly sounds like common style Molex pins to me, it will likely just be a matter of figuring our what size-type they are.
