commodorez:MARCH recently acquired a one-of-a-kind machine – a custom-made Philbirck analog computer made specifically for M.I.T. in 1958. A large portion of it’s processing is done via operational amplifiers, and almost everything is vacuum tube based (there are a few transistors on this computer though). It’s a very modular machine, designed to be completely reconfigured and rewired on a task-by-task basis.It is in serious need of restoration and probably a few dozen or hundred replacement vacuum tubes to bring it back to functional condition. It also had an era-appropriate oscilloscope used for diagnostics of the computer. -- source link
