I added a page for it: > http://mikenaberezny.com/hardware/c64-128/hatronics-hart-rs-232/ The trace for +5V (bottom left) seems to have gotten a bit hot at some time. That's what happens when you do the layout with all traces being the same size, even those that should be wider (+5V and GND). Also, whoever designed this was a bit stingy with the 100nF decoupling capacitors. I'm kinda surprised that it works.
