In case anyone wondered, here you can see the manual for one of their machines' video cards (I am not sure where it fits in their range).

Sadly both the display technology and the graphics memory are raster. I was hoping it would be something like the Vectrex or the Imlac.

My funniest Vector 3 repair was a client running Memorite (for lawyers a kick ass word processor for its time, think daisywheel monospace Courier/Elite printers) where the spelling of words flipped 'off by 2 letters' on the display as they edited. I knew the mapping for the S-100 memory card by heart and all the memory chips were in sockets, so I was able to go right to the chip in question and re-seat it to show them it ended the problem. Then I re-seated them all. Great work for a 16 year old!

Thanks, that PDF is a trip down memory lane. Display memory was indeed coming from 0hE000-0hFFFF. I taught myself Z80 from the Vector 3 manual. The whole BIOS source code with comments!
