 True but learning how to do this sort of think is what
I consider the fun part about these machines. Having a box
that works without understand what is going on inside
would drive me batty. I'm really frustrated when I can't
find a schematic for some of the things I have. I have been
known to trace schematic myself but this is really time
consuming and I'd prefer to get copies of originals.
 I don't have a piece of electronic gear that I haven't
at least taken the cover off of and looked inside.

 I tried to locate original software and also posted to this group
but the darn thing was a rare one. Finally a local friend found
some schematics and a little information. I still had to do
a lot of experimentation because the controller needed the right
information in the RAM that it was reading or writing to.
 I guess I am just a hacker at heart. I think that all collectors
should take on such a project at some point on some machine.
The knowledge gained is valuable for all kinds of things. I
will have some hardware to play with on my death bed.
