[net.micro.pc] Need help with STB board

dukelow@noscvax.UUCP (Robert A. Dukelow) (11/07/84)

My uncle has a system with an STB display board. I'm not even
sure what the model number is. All the numbers I could find on
the board were:
     STB S/N M1020
     1983
     APD-P86 94V-0
The problem is that it does only character mode. The guy he got
it from told him that he thought that it could be made to do
graphics by adding 6 2016 memory chips in the empty sockets (for
a total of 8). This sounded plausible, so we tried it without
success. Also played some with the switches with no luck. Does
anybody know how or if this board can be converted to graphics.
STB apparently doesn't want to talk about it and we don't even
have a manual.

Thanks in advance for any help.
