Vintage 1960s Burroughs Computer (B3000/B5000) Transistor Circuit Boards/Modules:
These circuit boards came out of Burroughs computer systems manufactured in the 1960’s. I don’t remember which system these are from as I had parts from both a Burroughs 3000 Series computer and a Burroughs 5000 Series computer. These were displayed in my classroom back in the 1970’s. Burroughs had a rather unique design with these plug in modules which has sometimes been classified as the “cordwood” style of circuitry which sandwiched components in layers to reduce actual circuit size. You will get 6 different transistor modules as seen below and 4 different diode circuits. One of the modules has a large aluminum heat sync top to dissipate heat from the power transistors. These are nice display items and show a different design in computer circuitry. I have included photos below to show details and the condition of these items. I have been selling these types of boards on for more than 10 years—a few sets a year. I just recently sold my computer collection to a museum and only have a few sets of these left to offer on .
Shipping within the United States will be by Priority Mail based on where you live. If you purchase multiple items, I will refund the excess postage to you when I ship your items.
