Godbout Static (RAM) But Not Lostby billdeg Total messages in this thread: 1 ![]() Bill Godbout died November 11, 2018 in the "Camp Fire" in Northern California, the worst fire recorded in the history of California. Bill Godbout was an early microcomputer industry pioneer whose company Godbout / Compupro based in the Silicon Valley was known for it's quality products. Godbout started as a surplus electronics parts company that expanded into S-100 bus peripheral card manufacture for MITS Altair and other S-100 systems. Godbout began selling complete S-100 systems in the later 1970's and changed it's name to CompuPro. The CompuPro line of S-100 bus systems were sold well into the mid 1980's.

Product Brochures and Price List
Received this from Classic CMP
"...One of the more interesting problems we faced at ROLM MSC (as opposed to
the telecom side) was the fact that all hardware was designed to be
tri-service. Salt spray and fungal resistance required that the cases
be sealed with thermal frames to conduct heat to external heat
exchangers, but that created interesting issues when sticking the box on
an aircraft (but was a lifesaver with disk drives, as otherwise flying
heads had a tendency to crash with altitude). The chassis ended up
being quite heavy due to the hammer and drop tests (as others have
noted,">... [ read more ]

I am sure he never saw it, but I once sold Vulcan Electrics, his computer museum project, my Xerox Star computer many years ago, for his computer museum. It's probably in a shed somewhere or stripped for parts.

Dan Roganti RIPby billdeg Total messages in this thread: 1 Dan Roganti.
Dan lost his battle with cancer and we all lost a titan in the vintage computing community. Dan was one of the earliest members of MARCH. He taught me a great deal about S-100 and related hardware engineering. Dan attended all of the early hardware workshops I hosted at my house and we had many hours working into the night on a wide variety of systems including but not limited to the MITS Altair, IMSAI 8080, PET 2001, Heathkit EC-1, ASR 33 Teletypes, Apple II, and so on.

Digital (DEC) PDP 11/05 NC Assemblyby billdeg Total messages in this thread: 22 Updated: [ 11/05 NC Power Connectors ] 08/31/2018 Ted Nelson speaks quite highly of the Digital PDP 11 series in his book Computer Lib / Dream Machines. ![]() Picture of the PDP 11/05 NC card cage and M9970(in the wrong slot). Click image for hi res version.
The only thing that prevented DEC from launching the PC revolution three years earlier was price, in my opinion. All of the other ingredients were there for a fine PC. The PDP 11/05 was the OEM version of the PDP 11/10, so you find all kinds of variations of this system sometimes paired with the DEC GT40 Graphic Display Terminal.
