> How long the internal memory can last
About 20 years ago, I had a yearly exposition of the big flemish Hobby Computer
Club. I was member (and later administrator) of the TRS-80 User Group, and
supplied most of the machines on display. Of course, I had a whole family of
Model T's on show. At the end of the exposition, where they had been running a
demo program all weekend long, I unplugged the machines from their wall-wart,
bagged them, and typically didn't use them any more untill the next year. (I
mostly used one T102 and a Model 4P, and several MSDOS/Windows machines) But,
several years after each other, when I started the machines for the next
exposition, I could find the software back that they had been running the
previous year!

Subject: [M100] Changing the Ni-CAD battery
Hi,
I got a 24KB Model 100 about one year ago and I've been using it a lot, but
after some loss of the internal data in the last month, I've checked the Ni-CAD
battery and it seems to show signs of imminent leaking.
So I ordered a new one (3.6V / 80mA) and I would like to know if there are some
advice I should know before jumping in and switching the battery, or some
tutorial about this.
Also, the user guide is not very clear about how long I should let the Model
100 switched ON to fully charge the Ni-CAD, which I assume I will have to do
once it's installed before I start transferring back my files to the internal
memory.
And since we're on the topic, can someone tell me how long the internal memory
can last without turning the model 100 on ? (User guide says about one week,
but I've been away for work for 30 days, and my data was still there when I
came back...)
By the way, this is my first mail on this list, so I'd like to thank you in
advance for your precious help!
Cheers,Eric
PS: Fun fact, the data loss was probably caused by a bad batch of AA batteries,
but I still prefer to change it since it looks like it has never been changed
before :o)
