Subject: Problem using DDT

This may be a problem specific to my system hardware configuration,
but I thought I would mention it to seee if someone knows what's
going on. First, DDT has worked fine on the system up to now,
and as a matter of fact worked partially for 3 or 4 steps one time
during this bug. Now, what I have is a 44k system running in 48k
ram, (the top 4k reserved for programs like BYE).
I just recently tried to test a program using the TRACE and
BREAKPOINT functions, and what I appear to see is the very first
instruction execute, then the system hangs, and I have to re-boot.
The instruction doesn't seem to matter, from an XRA to an LXI H,
I have run this on another system with the same files, and al
works ok, could this be due to my having only a 44k system??
I am not really interested in going too deep into this, perhaps
just a few hints/thoughts. I may just install another 16k and make it
a 56k or larger system. By the way the program I was trying to
debug was less than 4k in size...
Thanks for any help...
