The only two things Toshiba made for it were an internal modem (unique
to the T1000, not compatible with any other Toshiba modem slot), and
the 768K card.  This card has 768K of quasistatic RAM, which can be
configured as backfill up to 640K, expanded memory (EMS) or as a
nonvolitile RAM drive, or a mix of all three.  I found that not having
this memory to be quite painful.  My system is configured to have all
768K as a RAM drive, it's rather like have a rather small, but fast
hard drive.  I've seen the card for sale for about $250.

Other companies such as Megahertz also made internal modems for it.  Personally
I use a Novation Parrot 1200 pocket modem when I want to be portable.

A third party company had a backlight and battery upgrade.  I don't
remember offhand who offered it (Axonix?), I can dig it out of anyone
is interested.  The battery upgrade can be done by replacing the
batteries with larger ones from Radio Shark.  I've heard that they'll
last 14 hours.

It doesn't seem possible to upgrade any double density floppy controller
to high density, unfortunatly.  The next best thing would be to use
one of the various data compression programs.  Cubit and Stacker are
two that use a device driver to up to double storage transparently, these
are commercial. Pklite and xeq work on executables to decompress before
execution and are shareware.
