Radio Shack, in the newer versions of the TANDY-1000 series (SL, TL,
and newer) all have MS-DOS in ROM. The ROM emulates a write-protected
hard disk with NO free space. The boot device is selectable in the
system startup (stored in battery backed CMOS RAM) - as well as
certain default AUTOEXEC.BAT/CONFIG.SYS entries.
The pseudo-disk is implemented in socket ROM chips; the salesmen talk
about the ease of upgrade - "just replace the chip with a new one -
easier than upgrading from floppy..."
