I've looked at them and like most single chips MCUs
they are bizzare.
They also offer a windows emulator that pretty neat.

What you find "bizarre" is almost certainly what I like about them. 12-,
13-, and 14-bit wide instruction words, Harvard architecture so that
I-space and D-space are completely different concepts, remarkabably
efficient interrupt handling, remarkably low-power quiet modes,
etc. A refreshing change from the bland uniformity of the
8080/8086/6800-derived microcomputers that dominate much of the world.

You've been using them for quite a while if you remember the 13-bit ones. :-)
IIRC, that was the PIC1670 (not PIC16C70!); perhaps there were some other
13-bitters. That was before I started with PICs, though I have the old data
books around here somewhere.
