    Default Sol-PC acquisition

    I had mentioned this acquisition in falter's Sol Prototype Project thread but thought this could use a dedicated post so as not to clog up his original post. Most of this thread is similar to my original post but I have pics posted now.

    I have recently acquired a home-made Sol-PC with documentation from October 1976. The original owner appears to have been a Sol-PCB purchaser (paid $40). The Sol-PC Rev D board looks like the regular ďS-100 slot in the middleĒ board that is hand soldered, has a third-party ASCII keyboard from Electronics Warehouse (EW-100), a hand built power supply and comes in a case that looks nothing like a SOL-20 (clearly a third-party case as shown below).

    The Sol-PCB may have been purchased from the original Popular Electronics article from July 1976. I donít see any evidence of the Sol-PCB being sold in any subsequent price lists or this September 1976 press release but it is mentioned in the PE article so I believe this may have been from that original article.

    The documentation I have is quite sparse yet I believe it is complete. The cover letter is visible below. As noted in the letter, it comes with full schematics, a placement guide and other information for the builder. The components are all over the place in terms of dates so I donít think this was a pre-packaged kit. The personality module is also a bit strange because itís a 2708 version from 1977 (I think this was a replacement). The actual Intel 2708 is missing in one or two photos because, sadly, it is blank and I canít seem to erase what is left on it. It would have contained CONSOL since it is a 1k x 8 chip.

    The Rev D schematics are dated September 23, 1976 so itís not too far off of the article date. Full size and more pics are at my site posted here. Iíll scan the rest of the documentation and post soon.

    Cool to get a SOL computer and I really like that case almost as much as a real SOL case never seen a case like that one before.

    Thanks. I do love the "homebrew" aspect of this. It's a good example of the times. Incidentally, this came with an Ithaca Intersystems DPS-1 so I believe this was the terminal for it.

    I have scanned and posted my documentation if anyone is interested. You can go to http://vintagecomputer.ca/files-area/ and look in the Sol-PC folder.
