        Only yesterday I dear the pdf's of the Daybreak tech ref
manual (cited in this thread)! It was frustrating because althought
it corroborated everything I've discovered, it did not explained what
I have not yet discovered, namely the KEYBOARD CODES!!!
        Does anyone know the actual keyboard codes? I guess this is
the big question right now.

        I don't recall the excat values, but I got from a digital
osciloscope, the following values:
        HSYNC: 28kHz
        VSYNC: 76Hz

        I have a mono monitor with HSYNC at 15kHz and VSYNC at 50Hz,
which I was able to hack (!) in order to sync to the above values. I
use a simple transistor buffer to convert from the ECL output to the
75OHM load of the monitor. I can give you further details on this if
you want.
