As a general note: don't use the LOAD command to load HP system paper 
tapes.  Use ATTACH PTR <file> and then BOOT PTR instead.  See section 2.7.1 
of the (current) SIMH HP2100 manual, which says:

   Usage note: the LOAD command does not alter the A and B registers,
   whereas BOOT PTR leaves A and B set to zero after a successful load.
   BOOT PTR is preferred when loading HP software that may depend on the
   initial values of the A and B registers.

That may not be a problem here, but another list member ran into this LOAD 
vs. BOOT PTR problem last year with some other HP software that depended on
the registers being zero when the loader finished.

The current version, 3.7-3.  I also tried 3.7-0, and it worked OK too.

WinXP SP 2.

Send me the binaries that you're using off-list (my from address is good), 
and I'll try them here.
