Releasing in December 1990, the TurboExpress is quite simply a portable conversion of NEC's somewhat successful TurboGrafx-16 home console. Because of this, it's specifications are mostly the same as this aforementioned system, barring the obvious “portable” conversion that includes a 400×270 color screen.

- conio library functions work; - contiki crashes :(

Doesn’t fully work, but is the only OS of any sort available for the TurboGrafx-16/PC Engine. Since the TurboExpress is highly compatible with the TurboGrafx, it can be assumed this will work.

Whether these emulators support operating systems for these computers is unknown; it must be looked into further. PCs without meaningful OSes are not included.
