[Coco] Disto SC add-ons

[Roger Taylor]

Does anyone know how in the heck the addon with the video chip is 
supposed to output video or how it works?  The board also has a clock 
chip which seems to be running even though the board is old.. you can 
PEEK from BASIC and see the clock registers changing.  I do have the 
register specs on the clock.  The video chip is a CRT9128. There's an 
11mhz crystal, HM6116LP-2 chip, 13x2 header, and 2x2 header.  I see 
no other ID marks on the board other than the word "Disto" and two 
color stickers on the back labeled "M" and "T".

I see nothing in the Disto SC docs explaining the details of this 
board, just a mention that it's one of the add-ons.
