Well, yes and no. You can run DOS applications that do not require a
keyboard; to do this I think you might have to modify your GEOS.INI or
NET.INI file (or get the Expert Mode modification). GEOS does not multitask
DOS applications, it simply saves all running applications to state files
and shuts down. Actually, that's how File Transfer Mode works: GEOS saves
everything and runs a program on the ROMdisk (A:) called PCCOM. PCCOM scans
the fire buttons on the Zoomer and restarts GEOS when someone presses them.
