Is there a photo of the board ?
I find the whole concept, not only the processors very efficient. A bit of simplicity seems to get lost when going into the voyager series (regarding the display. It seems unnecessarily convoluted, most probably the result of being a stripped down nut core.

Yes, it is based on Woodstock as it was introduced in the same period as the HP-19C. The display interface was simplified a bit, "kiss" modelling :-) and doesn't use a mask in the B register.

Sorry I forgot. Yes, there is an inside view now. There is not much info on the web that I could find.

I'm a bit surprised they didn't use a simple Binary to 7 segment decoder. Maybe not thought of back then.

cheers
