- TRSDOS can already handle these specs, add the parameter of SIDES=2 to
- the format command (ex. FORMAT :1 (NAME="DATADISK",DDEN,SIDES=2) )
- As for the step rate, that can be altered using the command of:
- SYSTEM (BSTEP=n) where 0=6msec
- 1=12msec
- 2=20msec
- 3=30msec
-
- I do suggest, however, that you snag the latest version of LSDOS 6.3.1 as
- it will handle the correct dates, and has the latest SVC commands that
- the
- older DOS's lack (which is probably what you have), thus several programs
- may not work on your computer even though they are written for the Model
- 4.
