Check out your RAM chips (if they are 150ns chips as in my 1000SX) you
can reduce the system from 1 wait state to 0 wait states by swapping
in 100ns chips.

You could also add an 8087 math coprocessor (if you use QuickBasic, QC, Lotus)

The video ram uses the top 16k or 32k of the 640k ram. Either upgrading
to 768k (not sure if possible on a 1000TL) or adding an EGA card (which
will work with your existing tandy monitor - in 640x200 modes) will give
you better graphics and another slight increase in speed (reduces wait
states caused by the video controller accessing video ram).

I had great luck with an Everex MicroEnhancer EGA card.
