That's interesting. I suppose my XD88 was the replacement for the 4132.
It runs UTEK too, but of course on a newer 88k CPU. Unfortunately mine's
only got the 8 bit display board in it, not the 24 bit. I believe that
Tek sold hardly any of them, simply because they were way too expensive
- very nice machines otherwise.
