- 18kb system GROMs, with monitor and TI-extended basic II (no dump,
but source code is available and has been compiled)
- 4(???)kb DSR ROM for hexbus (no dump)
- 32(?)kb speech ROM: contents are slightly different from the 99/4(a)
speech ROMs, due to the use of a tms5220 speech synthesizer instead of
the older tms0285 (no dump, but 99/4(a) speech ROMs should work mostly
OK)
