[net.micro] simon's basic bug?

prindle@NADC.ARPA (05/24/84)

Gee, mine doesn't do that.  One (of many) peculiarities of simon's basic is
that it copies part of itself into the underlying RAM so it can safely page
out all ROMs from time to time.  Perhaps you loaded or poked into RAM between
$8000 and $A000 (32768 to 40960) before the list stopped working?  This RAM,
as well as most other RAM above 32768 is off limits with simon's basic plugged
in.  The screen clear/return to READY is symptomatic of a break interrupt
(execution of a BRK [00] instruction) which can happen real easily if a program
starts executing data!
