“Sparkler Filters’ IBM 402”
Hard skill to find! I started at IBM computer operations in 1967. Those machines were still around; but being phased out. I wired those 402 boards along with 548, 514, and the 85 sorter. They started me on the 1401 then advanced me to the 7010 computer. Hot stuff for the time.
Neat. Imagine investing in a basket of then niche tech stocks back then like that, getting the whole family tied into it, that would be lot’s of money and a big family today.
Ah yes, I remember. I stepped up to the 1130 and the 1620 after that. I think there was some PDP4 time in there too.
