C'mon Eric, you knew what I meant. MF11-L, I misread my handwritten notes.
I'm new at DEC Unibus stuff, and didn't catch the error :)

I've heard that's pure unobtainium.

I have had quite a difficult time locating M7891 modules. Still no luck.
This would be my choice as well.

My MF11-L is a G110, G231, and H214.
