I will have to take a look around my offline archives and CDs. I had the complete source of KSOS as it existed ca 1988 after certain changes were made at Logicon. I haven't looked at that data in years - it is possible that it may even have the original Ford KDNs (Kernel Design Notes). I'm *pretty* sure I know where it is. If there's any interest I can look for it later this week. Before and during early covid I was using SIMH to build a PWB system to serve as the dev platform for KSOS. I think I had everything EXCEPT the Modula compiler. For the life of me I can't remember which compiler it was. It was GFE as part of the project; it would have been the same compiler used at Ford. --tep On Mon, Jun 5, 2023 at 8:16 PM segaloco via TUHS <tuhs(a)tuhs.org> wrote: > As promised in the other email, I had one other tidbit worth sharing some detail on but that is very different from WECo promo and informational material.

These appear to be from the same microfiche as the documents linked based on splotches on the last page's date frame, although the copies I have here have the full frame, the PDFs linked seem to have the last panel cropped to a small square in the middle. Not super significant, but sometimes it's the little details. > > Anywho, unfortunately I don't have much to report, I got a bit excited while looking for these at first because I was having a hard time turning up PDFs, thought I had stumbled upon something unseen for some time, but in the gulf between last email and this I found them. Silver lining is one less set of documents to scan, but nothing to really expose that isn't already a click away. > > - Matt G.
