I wrote, last night:
In case anybody here is interested, I've
discovered a
satisfactory (to me, at least) resolution to this problem.
I downloaded Carl Claunch's DMS disk (dms32k25011403.dsk)
from
bitsavers.org. . .
Using this DMS disk (and with the appropriate changes to configuration
files and Fortran decks), the latest SimH Win32 build (from May 2, 2017)
works fine -- the simulator goes into Wait and allows access to the
GUI following a boot of DMS and after a job finishes executing.
No, it doesn't after all. By the time I got dms32k25011403.dsk working, I'd
managed to confuse myself about which SimH executable I was running.
The new DMS disk makes no difference as far as the GUI problem is
concerned -- the GUI only works as expected (and as described in
the Reference Guide from
ibm1130.org) for simh-4.0-Beta--2016-01-07-e8ea427d
(and prior) Windows builds (and with no throttling, in all cases).
Sorry for the confusion.
