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

[Bill Pierce]

That would be my question.... will it work under L2?
If so, with an MPI (or DW ftm), it would give 2 monitors. I know Gene used to run his like that so he would know more of the limitations there.

Alibaba.com shows a few suppliers available...

Rochester Electronics also:

Is this a board that can be easily replicated?
Will your L1 driver work under L2?

I did some quick research and it appears the "000P" is the same device
probably refers to plastic as opposed to ceramic packaging.  The bad
news is that they do not appear to be manufactured by anyone any more.

I wonder if there is some other similar but newer chip that could be
designed into the circuit?
