I have never experienced anything other than a corrupted file. I deleted and
that was that. After finding out what caused it, I did not do it again. I
suppose that depending on which point in a line it is not able to keep up with
on-the-fly tokenization some interesting things might happen.
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.
Merely
Ah, it is interesting to know how the dongle was used. I have never seen a
cartridge for the NEC machines, is it basically a box with a connector and ROM?

In my case, the driver transistor for the relay actually failed short. I
replaced it and the problem went away.
On a diode test the failed part was happily conductive regardless of what I
put on the gate, lol.

I've been asleep at the wheel.. I totally missed that Mcomm provides a very
good serial to IP modem function!
Once I realized this, I was online in an instant with my T102 at Greg's the
keep.net BBS.
Even more fun I was in 80x25 mode with the MVT100 adapter.
It was so quick and easy! Worked

Not sure what you mean by "won't work correctly."
Attempting to inload a BA named file that is not properly tokenized

The click you hear is the telco relay. The flux around the driver transistor
can turn conductive enough to trigger the transistor and thus the relay. I have
also seen this cause reset issues and other oddities on the M100.

I did just see this thread, and I want to provide a few updates.

Steve,
I purchased a clip-on book light at Barnes & Noble (Mighty Bright
https://mightybright.com) for use on my Nook eBook which worked well for
that. It is similar to the current ""WonderFlex rechargeable" clip on
light, but mine uses 2 CR2032 coin cells.

LaddieAlpha is uses the .NET framework runtime so I assume it works. But
confirmation would be good.

If anyone is interested in testing out R2.2 prior to release, let me know
please. I can send the files needed to upgrade the software. Suitable for
REX# and REXCPM.
Thanks Steve

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
ROM

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
One other thought I just had. Then testing Backpacks I use a REX Classic mainly
for TS-DOS. I have noticed that if I’m typing along too quickly in the TS-DOS
menus it will lock up as you describe. To prevent this, I wait until the screen
is finished rendering before pressing the next button.
I suspect the RAM is not wiped. The machine is just hard reset, and all
relevant pointers set back to defaults. Your data is likely still in RAM you
just can’t see it.

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
