Re: CBM900 keyboard

Since I've never gotten a video signal out of my own C900, I can confirm 
NOTHING.  However, Claus Schoenleber, from whom the C900s came, assured 
me, when I asked explicitly, that a PC keyboard works fine with the machine.

Again, I've never investigated due to the other concerns, but I would 
imagine cataloging the chipset should answer the question; at least I 
can't imagine them going for PC keyboard compatibility without also 
using the off-the-shelf chips to do so.

This is all speculation and second-hand knowledge, but for what it's 
worth, there you go.
