There weren't that many of these TI CP/M boards made. They were expensive
(about $500 or so for the board, if I recall correctly--not including
disk drives) and you were still stuck with the TI's wierd keyboard and
40-column screen...besides, these came out around the time that TI
was getting out of the "home computer" business anyway (although
the machine was still moderately popular for about a decade or so
after that).
