Not really earlie ones. The earlie ones didn't have disc drives at all, but
tape decks. Even the 160 kb Floppy was invented a little bit later...... AAMOF
my manual (german version of course) says roughly translated: The IBM
BASIC-Interpreter of the IBM Personal-Computer exists in three version:
- Tape
- Disc (floppy of course)
- Extended
These versiona are upwards compatible. Disc basic contains addons to tape basic
and extended Basic contains addons to disc basic.

The Manual was printed in 1983.

Further it states:
special addons of disc basic are:
- I/O to disc
- internal clock
- asyncronus filetransfer (RS232)
- support of two addon printers

...... it runs on machines with a minimum of 48k main memory :))
