Do you have more information on this? I would love to carry around a pocket XT
(that didn't cost $200 like HP 200lx's do)
He may have been referring to pocketdos, which I've just checked, and can be
found at:
www.pocketdos.com - IIRC it was about $40 - but the catch is that
you have to have a WinCE based handhelp - Pocketdos is just a software package
which emulates an XT on these devices.
I bought pocketdos, and aside from their registration system being a bit
clumsy (long user key to enter) and being tied to the ID of your handheld,
I have been pretty happy with it.
I haven't updated mine in a while (haven't found any problems), but I assume
the current version is very similar.
It simulates an 80186 and the hardware of an XT - so it knows the extra
stack instructions, no form of protected mode at all (which means no DOS
extender). On my viewsonic V37 which is a 400Mhz x-scale, IIRC it does the
equivlent of a 25Mhz processor, which is a tad on the slow side, but fast
enough for most DOS stuff. IIRC it's looks like a text mode CGA screen, and
I don't recall if there is any graphic capability or not.
It comes with DataLight ROMdos, which so far has worked for all of my
stuff, and you can define your own boot disk if you want to boot something
else. It has utilities to map "disk drives" to directories on the native
OS, and can also talk to the serial port (which I use as a portable download
station).
It's a but clumsy typing on the little keyboard, but they do provide a virtual
mouse driver for the screen - if anyone is interested, I wrote a little DOS
based file manager which lets you manipulate files, run apps etc. by tapping
lists and menus on the screen.
To put a bit of OT info in here, I carry all of my simulators on mine - if I
get the urge to show someone what it's like to boot up the Altair or H8, I can
do so "most anywhere" ...

Dave
