The Trackstar was basically a complete Apple II on a card that went
into a PC compatible. Well, it didn't have much expansion, so you
you couldn't add a Z-80 SoftCard, but that wasn't the market that it
was aimed at anyway. It required an actual Apple disk drive, since
PC drives require a format that respects the existence of the sector
detect hole. It was mainly aimed at the educational market, since
many schools had a lot of old Apple hardware and software. To the
best of my recollection, it was at least as Apple II compatible as a
clone could be -- I don't remember _any_ programs that couldn't be
made to run, and a lot of games looked mighty cool on a Tandy 1000
display. (While it would go into any generic PC compatible, Tandy
made a specific effort to market and regain market share lost with
their stupid decision to abandon the old Z-80 product line).
