Well, before I upgraded to a Mega-4, I had a Tech-Specialities board
installed in my 1040. It worked pretty well, although the installation
can get tricky. (The main problems being that on my board, one of the
ribbon cables was *brittle*, and actually snapped from being flexed
too much during the install. Simple enough to replace that, but it was
somewhat inconvenient...) Also, with most upgrades, you have to add-in
a plug to the video shifter chip, and the pins on that plug are easily
bent out of alignment. (Worse yet, easily broken.) Basically this just
means you have to be very very careful installing one of these things.

I liked the board though; I only had 2 meg installed on it, giving me
a 2.5meg system. I also got the clock option with it, which was a
handy addition. Note, however, that ocassionally the system would bomb
after booting up with the clock-setter. Dunno why, someone else told
me "it happens" and I left it... (Something about accessing the IKBD
after a boot...?)
