There were 3rd party cards, Monolithic Systems, for example.
The problem with the 11/20 is that hex wide cards don't fit, the fans

I would go to Iowa. Hell, it's not *that* far from Texas.

Guess I'll have to sign up in the a.m. so I can see the pictures.

I'm only a half hour from Boone. But, I can barely keep my 11/23 running,
so I don't think I would be a good owner for these. I offered to help the
poster if they want, as I don't want to see these scrapped either.

Indeed, Unibus is Unibus, except when it's MUD :)

Yes, the MEM11 is about 1/2 assembled at the moment (I just haven’t had the time
to finish it…you know WORK gets in the way).

I was able to get hold of a lot of boards which had been pulled from two
Decision Data's and a Western Dynex 2400 RPM 10mb (probably) drive.
The Dynex drive is similar to the RL02 and in fact was configurable to
look like one in one of the options. Microdata would have used 24
sector packs

Yep. Simple and spread across multiple cards.

Some time ago I came across the MC6839 ROM which contains floating point
routines for the 6809. The documentation that came with it stated:
Written for Motorola by Joel Boney, 1980
Released into the public domain by Motorola in 1988
Docs and apps for Tandy Color
If you are concerned about hex height boards or mos, you can always use a
BA11-KE expansion box.
