I had a bunch of 2260/2848s in my territory. For a while I was the
only one trained.
Another interesting thing was it had tubes in it. The rumor was this
was a Toshiba TV design based on the compactron tube set it used.
We did have one guy who got fired when they found out he was fixing
TVs on the side, using IBM's tubes. He was pretty dumb about it. He
didn't even try to coordinate his tube orders with 2260 calls.
