Hallo Bil,

> Some schematics for some odds and ends, more coming.

Thank you! I had a look at it and couldn't understand one thing: how 
can I write to the video memory? I'm used to schematics where either 
the the processor can read from/write to the video memory to the 
6x45 can read from it. 

MA0..13 are outputs of a counter that cannot be set to a certain 
value by the user, that is, AFAIK. If it can, OK, but then I still 
imagine that, for example, clearing a screen is a time consuming 

I hope that I'm wrong and missed something. I'm looking forward to 

Kind regards / Met vriendelijke groet, Ruud Baltissen
