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. Tony> What are you using for a monitor? At a quick glance, the Tony> Daybreak monitor has ECL inputs for sync and video, and no Tony> idea what the scan rate is.. 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.
