RE: Kopin microdisplay

ah, you need two things then.

First you need something to drive the display

Then you need something to be your terminal device...

The av-1 could take the serial input then create a stream that would
usually get converted to NTSC, but they skip that part and send it into
the Motorola chip that takes NTSC in, but go around that part so there is
no D-A-D conversion....

Or it could go D-A and then A-D again.. if you do that then it will be a
lot easier. you can get a BOB or a BOB-II and write code to use it as a
terminal in linux.. a BOB and a RS-170 OEM driver board will be pretty
small.. you could always rebuild it smaller or different...

but driving it directly will probably be more complicated...

good luck and keep the list updated,
