If you turn the machine on with no disk in the drive and no cartridge in
either slot, you get ROM BASIC.
There is also a more advanced BASIC on a cartridge. If you turn the
machine on with the BASIC cartridge in a slot, you get cartridge BASIC.
This is not a guess. This is how my PCjr behaves.
That's my understanding. There are three levels of BASIC for the Jr.
Level 1 is the ROM BASIC, level 2 is the disk BASIC and level 3 is the
cartridge BASIC. I was surprised that the cartridge BASIC was the most
complete but that's what the manual says.
ROM BASIC = Cassette BASIC, subset of BASIC included on all Family Ones and
PS/2 through 8570. Able to load software from, save files to cassette. Also
handy on later models for twiddling the CMOS in the event of hosed setup
preventing boot, etc.
DISK BASIC = A "loader" that hooks into the BASIC interp. on the ROM cart.
Cartridge BASIC = The real honest-to-goodness BASIC.
