My B128 (was from someone who got it from PRotecto when they were
liquidating them in the 80s) has a 5-pin video DIN (anyone know the
pinout?), but my P500 has an 8-pin one (like the 64)....  :-/

That *might* just be,I have a lousy Quickcam pic of my MB here and it
looks like it comes from a connector like the keyboard uses (single or
double row header) to the two joy ports. 

Comparing the two images (mine and that side-by-side one) the image the
of the 2 B-Series computers the one on the right *looks* exactly like my
P500 MB.  It could possibly be retrofitted into a P500 with a little effort.

I'll try to dig out the P500  and snapshot it today.
