It's special to me because I need it to use the machine it came with and to make more machines.

That's about it.

I guess I also like annoying people on Discord by posting a picture of my cat sitting on it.

If anyone here ends up buying this and wants it to be more than a decoration, drop me a line and I can get you sorted for an interface and (if necessary) firmware.

Attached is the LMI Lambda keyboard's 8748 software, the LMI equivalent to CADR's "ukbd". This only matters to you if you have a LMI keyboard with its "brad board". If you have such a keyboard and your 8748 has bit-rotted, this will revive it. (The image is also being sent to bitsavers and such ...

So you have one lisp machine for sale, right? :D


I wish; They were not stored well - open to sky for more than 20 years. Lots of rust and mold. If even one winds up being restorable it will be a major achievement. That said, someone once restored a PDP-11/45 that had a literal tree growing ...

Please excuse my unfamiliarity with keyboard stuff; I never really paid attention to them. I generally used whatever came with the machine unless it was exceptionally irritating, in which case it was replaced with whatever was at hand. I was sent here by recommendation.
