I'm very interested in doing the same (stuffing a motherboard into a separate box)... especially now... this "air blower" is ready for take-off. As of several weeks ago, with the addition of an inverter for the vert sync signal, the external "Hercules compatible" monitor is more-or-less working. The only remaining problem yet-unsolved concerns "missing" pixels at the left hand margin. For example, rather than seeing, say, "ksh> ", I get ":sh> "; that is, only the ends of the arms of the "k" are shown; same problem with the missing left sides of UA menu windows. Attempts to insert numerous inverters in the video-signal line in the hopes of delaying the video after the horizontal sync haven't produced any noticeable improvement. One person is bringing over a delay line and we still need to try that out; luckily the delay line is in a 16-pin DIP package and provides "taps" at a number of delays up to and including 100nS. More details as they become available ... Someone else was proposing a complete re-vamp of the 3B1 video to use one of the TI 32010 (34010?) or 32020 (34020?) programmable video chips for everything; as exciting as this sounds, I don't have the time required to commit to a project of that magnitude.
