This is almost certainly software.  your i23o123.icb file is trashing
the interrupt vectors and the board crashes.

AAaarghh. I soldered in the final connections for the outgoing
pulse-trains from TOC2.  I use the Handyboard to take in pulse trains on
IC2 and IC3, massage the numbers, and output the massaged commands on OC2
and OC3.  Only the signals go through the board, the power is external.
Up to now, everything had been working while testing OC2 and OC3
individually, but now, when I fire up IC with code using both outputs, it
establishes communication with the Handyboard, says

loading sigproc.c.
loading hbtest.c.
loading i23o123.icb.

and the process hangs up at that point.  It doesn't start loading
interrupt vectors, just hangs.  Rebooting the DOS machine and
reloading the pcode into the Handyboard doesn't help.  The heartbeat
continues on the Handyboard when the hang occurs.  Does this sound like a
hardware failure or problem?

Thanks for any beneficial neuronic activity... :-)

(...) But the hearbeat continues on the handyboard, and the software worked before I soldered the Futaba J connector on, hence my thinking that I hurt the board and caused a hardware failure. Could a hardware failure make the board crash at this (...) (29 years ago, 21-May-96, to lugnet.robotics.handyboard)
