Nice. I wouldn't turn up my nose at either one.

One of the reasons that my MEM-11A project has been
delayed
(other than not having enough time and other life issues) is to
provide enough functionality in one board to be able to run Unix
v1.
Cool!
Right now it contains:
- 128KW of memory (because getting enough memory
reasonably in an 11/20 is hard)
No doubt. I have somewhere between 4-6 memory backplanes
and card sets minus at least one core plane (saved by a fellow
employee who helped me rescue this machine from the dumpster).
I _might_ be able to get it back from him _if_ I sent him another
plane with a clear cover to hang on his wall.
I should have a better handle on what I have and what I need
in the next few weeks when I move this and other "interesting"
items.
- KE11A/B functionality
Sweet!
- 2MW of RF11
Sweeter!
The goal of this board is to be able to have a
complete Unix V1
11/20 system contained within the 11/20 CPU chassis (other than
the RK05 drives).
I was going to get a MEM-11A *anyway*. This makes it so much
more appealing. Now I might get two, one to leave in the 11/20
and one to float between my other older Unibus machines.
Sorry, but I don't have a completion date yet.
No worries. I wouldn't have my 11/20 in a working state this year
anyway. Too many other projects in the pipeline. If I didn't have
to completely re-do all the DC power supply wiring, it might be
feasible.
