I'm not all that familiar with this whole area but because I have a
Rex 600=
0 and 2 unused mailstations, I thought I'd ask if source code
for the Rex a=
pplications could be reused with the nifty mailbug
software that I see in t=
he files section but haven't tried? I rarely
use the Rex anymore but do ha=
ve a bunch of files saved that have the
source code for some small apps and=
games.

The mailstations I would love to make into a portable word proce=
ssor
(for me) and a pre-schooler's "laptop" for my grandsons. Is that
anyw=
here feasible yet or even for the near future? I was just
wondering the ot=
her day if I should just put them in the Goodwill
pile. The kids get bored=
playing with the keys without any feedback,
so they are useless even for p=
retend. Well, especially with the other
computers on and nickjr.com at the=
top of the bookmarks... :-)

Thanks,

Terry

p.s. I am a software tech b=
y trade - which means I can usually
recompile source code if it's fairly ge=
neric and I have flashed my
pdas and done some work with the Keil emulator =
software - okay I just
made the lcds blink but it was fun... so my skill le=
vel isn't nearly
enough for hardware modding without the "for dummies" docu=
mentation.

Hi,

The short answer is: "no=
".

A longer answer: Not without a lot of work.
Any input or output, or for=
that matter any calls
to the OS would have to be mapped to alternative
cal=
ls to the mailstations OS. Unless, by some unlikely
coincidence both the r=
ex 6000 and the mailstation
have the same low level firmware.

use the Rex anymore but do have a bunch of files saved that have the
rce code for some small apps and games.

Is the source code in C or assem=
bler?

I had never heard of the Rex 6000 before now, but I googled it,
and =
spent some time reading about the hacking efforts last night.
Seems they ar=
e quite a bit further along than us! (Heck, they were
further in 2001 than=
we are now!!!)

Although the hardware is quite similar, I imagine there wo=
uld be
a lot of work involved in porting a rex 6000 app to mailstation,
not=
the least of would be reversing the existing mailstation OS,
or writing a =
new one.

At one point there were a few group members who wanted to
complet=
ely rewrite the firmware. I haven't heard much lately
about any efforts in=
that direction. My own plan was to reverse
enough of the existing firmwar=
e so that we could use the existing OS,
but that isn't moving very fast, ei=
ther.

sor
nywhere feasible yet or even for the near future?

Define "feasible"... =
:-) :-) :-)

For something like that, you might have more luck with an Apple eMate. The=
