A friend of mine has a working Einstein and thinks he
has Xtaldos
and possibly another OS (pseudo-CP/M?) for a 40-column system.
There was apparently a genuine CP/M version for an 80-column
machine, but he doesn't have the 80-column add-on, nor real CP/M.
Unfortunately, he's about to go on holiday, so it
will be at least a
couple of weeks before he can look for disks, but I've saved your
mail, and will remind him.
Thanks Pete. My Einstein came with the 80 column add-on so now I've
got something else to find :-) i.e. the genuine CP/M as well as
XtalDos.
After changing a few jumpers in the 80 column add-on, the Einstein now
works with the Phillips mono monitor I use with my BBC Master.
