Need a RS232 interface transputer tram

I wonder what happened to the "app-note" type designs that were floating
around about 15 years ago. It was hard to get them to stop sending them to
me when I was working at the "Rocket Ranch." They were purported to be
small and simple, intended for ganging up on a task, and not my cup of tea,
so I never bothered to save them. They must have had a serial (RS-232)
version, because I considered them for a hugely parallel test fixture for
proving that yet another Honeywell-Bull system proposed to the Pentagon
didn't work as advertised. We built a single board system which filled a 6'
rack, with 68701's on both sides to perform the test. It proved the system
didn't work, but the Pentagon bought it anyway.


It's nice to know that your work matters.
