I have a Technico Super starter board and it runs the
TI9900 at 4mhz
with 16bit wide memeory and rom really fast compared to the Z80
(comparison made on both machines I still have from 1979!). I picked up
the TI99/4a and was sadly disappointed save for the bundle of
really good and inexpensive software for it. Still, it plays a mean game
of
Parsec!!!
Parsec is the main use of my 4A...it's the replacement for
all the quarter-dropping days playing Defender. When playing Parsec
though, one has to have the Speech Synth plugged in! It's too bad TI
killed the idea of additional plug-in modules to add to it's
vocabulary.
