Not sure what you mean by
The internal battery always preserves the ram contents as long as it's a
working battery.
Reset can happen fairly easily from crashing software, but it requires
some sort of software error, IE either a bug in the software or a
corrupt copy of the software from a bad serial transfer.

A particularly nasty crash can make it do that cold-reset thing. I ran into
that countless times while trying my hand at assembly development while using
ROM2 and MFORTH
Loading a .DO file which has been incorrectly named .BA won’t work correctly

Although not having seen this ever crash my T102, I did notice that having
my Seiko DP-414 printer connected, but turned off, causes an increase in
current draw on the T102 (likely on the M100 as well). Several 10s of
milliamps if I recall correctly. Does cause the red LED to come on if

TS-DOS? The only problem I know that causes corruption with TS-DOS is
mistakenly trying to inload a file named with a BA extension that's not
really a tokenized BASIC file.
You should always rename ASCII BASIC files as .DO before inloading. You can
inload a .BA file, but it must actually be
Thanks to all, I have a lot of things to investigate now. Jeff : indeed , I've
never been able to reproduce the problem "on demand", but each time I remember
crashing, I was doing serial communication or "saving files", so more than
likely using TSDOS. So that's one area I'm gonna investigate.
A particularly nasty crash can make it do that cold-reset thing. I ran into
that countless times while trying my hand at assembly development while
using ROM2 and MFORTH. in that case the problem isn't that the memory is
totally erased but that some important part gets corrupted and the stock

You are getting a cold restart for sure. That is the result. What causes
a cold restart? Memory corruption, specific bytes in upper ram. When the
computer does a restart from instruction , it will
it.

Hello,

If you can, please try to replicate the problem without a REX# involved.
Maybe I missed something with R2.2.
Rs232 does load up the lower supply a bit. There could be a problem with
that aspect, but it should be the same with or without rex.
Thanks

It's not normal at all. The backup battery should absolutely protect the
RAM even if the main batteries are dead.
Do you know if the backup battery is getting charged? And I guess the
memory power switch must be on since I don't think it works with it off.
I guess you would need to remove main
