D-SUB9 RGBI expanded to 2 ports

[MIRKOSOFT]

Hi!


I have big Q before I'll try anything.


I want from one D-SUB9-F output on Commodore 128 expand it to two D-SUB9-F.
Create a diverging. Not on MB, but through 9-wire cable.
And the big Q is: Is it really possible?
(look at scheme in attachment)


Thank you very much for reply.

Yes it is possible, as the output from the port is just TTL-level signals like you might find on the IEC serial port.

That said, it was only intended to run one monitor at a time, so you might want to buffer the port first, perhaps with a 74*365 (hex non-inverting buffer) or a 74*210 (octal non-inverting buffer).  You could probably use a bunch of good transistors if that's all you have.

Whatever you use will require power, but you can draw that from the cassette port.
