Thread: Bi-Tran Six

    The Bi-Tran Six was the first computer system I ever trained on followed by the KIM-1 at the State Technical Insttitute at Memphis in 1977. It would be great if you would post a picture of it for old times sakes.

    Yes; the Bi-Tran Six was my introduction to computers followed by the KIM-1 at the State Technical Institute at Memphis in 1977. It would be great if you would post a picture of it for ols times sakes.

    Oh my! What a flashback.

    We had one in the laboratory at Schoolcraft College in Livonia Michigan around 1972.

    I recently became the owner of a FABRI-TEK COM-TRAN TEN. I am trying to get it working again. I downloaded the pdf manual with KDA3032 but would like to find circuit diagrams and I.C. layouts for more of the main circuit board. Probably the rest of KDA3034. Many of the I.C.s don't have their labels anymore. The one I have is I believe an early one. I.C.s have date codes of 1968 through 1971 and the serial number is CT-0002-C2. Probably from 1972. It uses the Model 422 Magnetic Core memory, Serial Number 68373. It was the property of Cincinnati Technical College back in that time frame. I have a lot of computers that I use for STEM education including a Relay Based Machine I designed and built. I think the COM-TRAN would add a lot to my demos.

    Yeah, I'll believe it when I see it. A picture or six would be nice for old times sake. Core memory and all that stuff, if I remember correctly.
    Here is a picture of our first lady from Slovenia promoting STEM education. Whooda thunkit?

The training material and equipment were simple, but the instructors were top-notched. The computer lesson was brief, about 1 week of a 20-week course. At the time, most of the training was analog based. This short digital encounter with the Bi-Tran Six stood out and planted seeds for the future. A little while later a "personal training computer" was purchased, the $250 Kim-1. Off and running, a career was started based on the simple computer in your post. I sit here today, typing Python code with many powerful, graphical development tools, but there was nothing like learning the basics writing machine code, punching it in, and watching the lights flash! Please keep that baby running...
    To bad dlarue doesn't appear active I wonder if we might have met because I also trained as an Instrumentation Mechanic at Lowery in 1974 - in fact I still basically work the same job except as a contractor at Cape Canaveral for satellite telemetry systems. Some times I use to think the Bi-Tran 6 was something I made up since there appears to be very little data on it.
    Who let out the magic smoke!!!!!!!!!!!
