PDP12 and PDP-8\/L<\/figcaption><\/figure>\n\n\n\n

I have three machines from the PDP-8 family of computers: a PDP-8\/L, a PDP-8\/m and a PDP-12.<\/p>\n\n\n\n

\"PDP-8\/L\"<\/figure>\n\n\n\n

The PDP-8\/L was the first minicomputer in my collection. (Though I did own the Altair 8800<\/a> at the time). It was purchased for around $250 (in part a birthday present from my wife) from the “Second Bytes” used computer store in Milwaukee, Wisconsin. The system has 4K of core memory in the main unit, and an additional 8K of core in an expansion unit. (The expansion unit is just below the PDP-8\/L in the combined PDP-8 PDP-12 picture at the top of the page). I got my ASR33<\/a> teletype as part of the deal. Although the ASR33 has worked well for a number of years since then, it has recently become somewhat cranky. More than anything, it probably needs proper cleaning and lubrication. Fortunately, I do have the appropriate manuals for the job, if not the training and skill. <\/p>\n\n\n\n
