Hi. I have a Xerox DayBreak workstation lying on a corner back home and I'd really much liked to do something with it. I have already posted emails to this list about this subject, but since so much time passed since then I resolved to re-post to see I get something new. The issues I'd like to solve are: 1. decent interface of the display output to some monitor -- I worked on a small circuit to convert the ECL levels and separate syncs into a composite video output, for a mono monitor, using discrete components, but the image was sort of fuzzy. Are there any ideas on doing these the right way (if any)? 2. interfacing the keyboard/mouse connector to a PC's serial port -- I managed to build a decent interface for this (using a MAX232), but now the problem is protocol: anyone knows the protocol for sending key presses/releases signals? I believe they have something from 1 to 3 bytes. I have a set of PDF of scanned Xerox manuals (TechRef and IOP) including some schematics (awesome work! congrats for the one who scanned them and put them on the web!). But they don't specify the keyboard protocol. On the other hand, I also got PDF's of the MESA manuals, but they describe teh keyboard interface at the API level (no luck there either). Any help on these issues is very welcome!
