I did a little more investigating and I can confirm that switching to
the SP state while a program is waiting for keyboard input is what
dropped me into the monitor, and it's expected behavior per the manual
(also happens during a BASIC program).  If I switch over while the
program is loading or doing something else, I appear to be fine.  So
all in all, I can say the Senior Prom design with your hybrid firmware
is functioning exactly as it should.

I would still love to get a copy of the official //e firmware of the
Senior Prom, just to look at the differences if any.  I sent an email
to A2Aviator who is apparently an avid Senior Prom collector but
haven't heard anything back yet.
