#PDP 11 70 JAVASCRIPT EMULATOR SOFTWARE#
Luckily I was allowed to have the most access to it as I was charged with writing the operating software for the state-of-the-art image processing software that was vital for the entire department's ongoing research projects.
While the start up sequence completed there was time for a coffee - now that's a bad memory 1970's instant coffee - before being able to get on with my project - except that almost inevitably my room mate would have arrived in the interim and taken over the machine we shared with two others. I did it so often I'd memorized the sequence and could input it in around 20 minutes after which I'd load the paper tape. They were used to input the sequence in Octal. You see the piano-style keys numbererd 0 t0 31 to the left of the white spacer key grouped in threes. Remember the 1970s, it was my job as the Department's junior member to key-in the PDP-11 load sequence every morning. This PDP-11 project takes me straight back to my days as a PhD candidate at University College London while at the same time chiming with my current absorption with the Rapsberry Pi family. Reportedly, 600,000 units were sold over its long life, and it was the tool of choice for countless computing innovations, including the creation of UNIX and the C programming language. The PDP-11 was DEC’s first 16-bit computer, and cost $20,000 when released in 1970. Retro Viator gave his account of the PiDP-11/70 from Obsolescence Guaranteed, which is a small-scale replica of Dec's PDP-11/70, a landmark mini computer of the 1970s. My attention was attracted this week to a vintage computer kit building experience.
