Actually, I can get into the TWGS config menu which
is fine until I open one of the menu items, then the
screen goes wacky. I can still change settings, but
it either crashes on save, or pretends to save and
doesn't. The 0202 message on one chip changes after
I do a save to config, and the one doing a 0201 is
also 0201 with no chip, so I assume that chip is not
being recognized at all.

: Just doing a re-write to an EEPROM will often
: fix a marginal programming job.  (I presume that
: the error message is prompted by getting a bad
: checksum, or other inconsistent reading.)

As stated above, I can work my way into the config
program by doing a reset and quickly pressing Option,
then I leave the control panel and quickly do a OA-
Control-Escape, at which time I can get into the
TWGS menu. I checked the voltages on the EEPROM
socket and I get +5v at Vss, Store, and Recall,
which are normal being Store, and Recall are both
Active Low. I would check their voltage during a write
if I could get the meter on them while pressing all
of the keys necessary while they are connected to the
DVM. I'll see if I can get a reading on that after
the holiday.
