Mmm, yeah. If I can get the HT working on my VT100 I could probably tuck it in there. Good idea!!!

Heathkit H11A Gett'er Working Thread.

The 11/02 CPU board-set actually has to sit and think for a while when playing text adventures, it's that slow!
I believe I still have a Falcon+ board. I've always wondered what to do with it, I guess one answer would be tuck it into a VT. I have a VT-62 that is of course pretty useless, since I don't know anyone that has a way to get them to do useful work, so the idea of tucking something in there has appeal. Ah, endless projects. I'm very glad to see you are making good ground on getting your H-11 going at least!

I wrapped my test-rig backplane for 22 bits and started testing my "new" RAM cards.

Final magic-smoke release test before transplanting everything from the test rig to the actual H11.
I still need to convert the H11 backplane to 22 bits though.

Well! I finally got back into this thing. Converted the backplane to 22 bits, and moved all the cards over from the test rig.
It seems that I still have some power supply issues! The front panel only works intermittently, and whenever I turn on the LTC the power supply crashes and resets the system. Oof. I'll look into that later........
