Integral RAM upgrade

Now, perhaps, you can understnad how I feel when something is described 
as a simple bit of programming (either for a PC or a microcontroller). 
What's easy for one person is not necessarily easy for another. This RAM 
upgrate was very much a p[roject o fill a spare afternoon while I was 
thinking about _another_ classic computer repair.

[For example, getting back to that cassette decoder thread, I don't think 
I could write a tone decoder program for a PIC off the top of my head, 
and I certainly couldn't for an AVR, as I've never used thar series of 
microntrolelrs at all. But the pinouts of most TTL chips are in mask-ROM 
in my brain :-),. and I have a well-stocked junk box. Get the picture? ;-)]

Well, I decided to descrie it stages becuse 'Fit the extra RAMs and 
change the links' doesn't make much of a posting...
