[GreenKeys] INKTRONIC on EBay

[Andy Williams]

I worked on some automated test stands in the early 80s that used the Varian 620 as the controller. They had huge circuit boards in them with a mixture of TTL and DTL and a 5 MB hard drive the size of a washing machine tub that had to be pressurized with atomic grade helium. I remember fixing one computer that had bad electrolytics in the power supply, a problem I’m still dealing with in antique radios. The older test sets used model a model 35 KSR as the terminal and newer ones used a model 43. One of the 35s had an intermittent printing problem, so I got the teletype shop to clean and align it and it worked perfectly after that. Afterwards, the teletype tech told me that the printer was so gummed up that he had to clean out the ultrasonic cleaner.
