Sadly, no, and you're not the only one who wants one. You can play around with
it in VirtualT to get a hands-on feel for what it does for you, but there are
two main advantages (and why I would nearly kill to get one myself):
- You can load images of other option ROMs into REX and switch between them
at-will, to use other software which was made for these machines without having
to hunt down the physical ROMs or the hassle of swapping them in and out.
- You can make multiple backup images of the contents of your machine's RAM
into the flash memory on the REX module, and switch between them (like I was
describing with TBACK in my last message). In fact, what I was doing with
TBACK was inspired by having used REX to switch between multiple RAM images in
VirtualT. This means you can make a backup of your RAM on the fly, and if you
have to cold-reset and lose everything you can restore in a matter of seconds
without any external hardware.

Bear in mind, when you add the 8k you will need to do a cold reset after
installation, which will wipe the contents of RAM. I could be wrong but I
don't think you'll be able to use TBACK to back up a 24k machine and then
restore into a 32k machine... John, comments? You'll need to transfer any new
or modified files out and then transfer them back in after the RAM upgrade.

mComm is my favourite now. Kurt posted a solution for bootstrapping TS-DOS
into your machine using the cassette interface cable (if you have one).
Unfortunately, that's the whole TS-DOS executable, which you don't really need
if you're using mComm - you only need TSLOAD.CO which occupies a lot less RAM.
Kurt, do you know if there is an mp3 of TSLOAD.CO or would it be helpful if I
made one?
> 4. With AA batteries so cheap, do people use the AC power adaptor?
I haven't felt a need to use an AC power adapter, but I haven't been sitting
using mine for hours at a time either. My kids have, but even then I haven't
put as many batteries into their m100s as I have into some of their other
electronics...
I have other power adapters I could use, but haven't bothered. I have a T200
in the mail coming to me some time in the next couple of weeks (cross-border
mail is slow) and with that I will get my first official Tandy power adapter...
