Thread: Wanting to buy GRiD 1660C, 1680, 1680C, or Panasonic CF-480

    Default Wanting to buy GRiD 1660C, 1680, 1680C, or Panasonic CF-480

    Wanting to buy GRiD 1660C, 1680, 1680C, DECpc 325p, 425se, or Panasonic CF-480/comparable Panasonic systems. They're all derived from the same design and I ended up collecting several of them (Tandy, Siemens, DECpc) and want to complete the collection.
    Attached is a picture of the most elusive 1680C. There's a few other models that overlap several vendors, one overlaps with Texas Instruments, another with a Zeos, but this one seems to be the only that overlaps with GRiD.

    Glad to see you are still at it, Caleb

    Haha yes I am and I'm sorry I kind of fell off with the capacitor research, I moved and got busy with school and other projects...

    No problem at all. Your contributions were invaluable. You essentially solved the problem. I actually got my hands on a GRiD 1755 that was still functional, but clearly suffered from DC-DC issues that were due to the capacitors, which confirmed the theory 100%. You basically saved several series of systems spanning a decade and several manufacturers. The vintage computer community is far greater for your involvement.

    Now that I know you are looking for a 1660C, I will be keeping my eyes peeled for one. It's the least I can do.

    Are you also looking for the docking station for it? Just want to know if I should keep an eye out for that as well.

    Well... Thanks, haha. I actually didn't know you got around to fixing your 1755.

    Yeah for sure, I don't expect to see a docking station but I imagine it would be compatible with all the models I have, that would be cool.

    I found out another model to keep an eye out for, Panasonic CF-480C, which is the model the 1660C is based on. If you can get one of those, you can swap it into the case of a plain 1660

    I learned something about the 1680C. It turns out it is another one-off by GRiD, a derivative of the Matsushita CF-480, with significant modifications. Much like the 1755\486SLC which was a one-off by GRiD, a derivative of the Matsushita CF-380, with significant modifications so it could run the Cx486SLC processor correctly.

    Unfortunately, that makes the 1680C all the more rare, since it was a GRiD only model. I have no doubt if you look long enough, one will surface (just make sure to keep current with SearchTempest so you can rake Craigslist, and keep an eye on Reddit, more and more people are selling vintage IT there)

    Thanks! Incidentally, I actually have a 1660C now, but it is damaged and non-working right now, and I'm looking for another one. I certainly don't have the 1680C yet though, or the 1680. Most significantly the 1660C has a thicker screen and top lid/case, so the whole top is taller, but does not affect the lower portion.

    Found a reference to the Matsushita version of the 1680C, a couple cached images from google:


    Its a 580/580C.
