A Wee Cristmas Present

Cool! Of course Bitsavers has had the Monitor 11 listing for a while, in PDF form. I was trying to look through it to see whether or how the Monitor might be able to run off of a ProFile, but never really followed through on that.

some more information on CHM's lisa prototype. need to get pics of the other boards in it

and the yaccintosh

Wow, whole lot of "Believe me, you really do not want to know how this works." in the Yaccintosh PDF.

I never thought I'd see more pictures of that early Lisa proto past what Digibarn put up all those years ago. Really cool to get the firmware too! I wonder what would happen if you put that firmware on a production Lisa... Didn't I also hear the Lisa was supposed to have fancy audio capabilities and that's what those two 3.5mm jacks on the back were for?
Now if only we could get some good, high resolution shots of the prototype colour card.
Thanks Al for everything!
Al Kossow:
we have all of that stuff

it is unlikely the prototype firmware would do anything in a production machine.
for one thing, it appears to have 2651 uarts on the cpu board. the code in them
is tiny, it's probably just enough to boot the monitor as described in the early
pascal monitor document
