Ok, here is one for the true wireheads among us.
I finally got some time to start working on the PDP-8/i in my collection,
and started keying in some test programs with the intent of getting the
timing on the TTY interface tweaked in so I could load some serious
software, and found that the old beast seems to have an odd problem.
See if anyone has hit on this one and has a suggestion...
I can't seem to write into location 0 on any memory field?!?
Regardless of what I write into the location, it always reads back as
0000.
I can write into any other location, and all of the primary logic
functions seem to be ok... (I can load/run programs as long as they don't
need location 0)
The 'write all zeros' test program (that org's at location 4) runs as
expected...
Thots, suggestions, comments, eek!?!
