A BUNCH of 9100 cards and programs

[tubenewb]

As part of my recent acquisition, I also came into possession of 28 rewritable magnetic cards, about a dozen that have been cut to be read-only, and a few diagnostics cards.

The previous owner used these calculators since as early as 1971, and as late as 1993, based on the dates on the cards. The programs on the cards are mostly focused on radio signal and antenna design modeling.

It appears as if he was trying to troubleshoot some problem with one of the calculators at some point, so I may be in for a challenge if I intend to get them working.

(and yes, there is a 9125 printer to go with that diagnostics card - I’m still cleaning it up)
