[Coco] OS-9 80-column driver is ready

[Luis Antoniosi (CoCoDemus)]

Well I call it protype because in fact it was a prototype made in 1985 by
some company called PHB in Texas. Is what is written in the label :P

I'm doing the schematics and I will try to make it in protoboard, but it
will take a while since I'm a software guy not a hardware.

But yes the circuit is so simple that it can be easily copied. I think the
most difficult part is to find the CRT9128.

I found in china the CRT9128-000P.  I hope is the same ? If the protoboard
works I can see the possibility to make a batch of it.
