Usage

This section covers day to day usage of SDX Plus, and covers common hints and tips.

Resetting

If both Shift keys are pressed during reset, it doesn't boot CP/M and returns to BASIC instead.

Accessing RAM Disc from MTX BASIC

You can switch to MTX BASIC, and use ROM 5 to gain access to the floppy disk and RAM disc via USER commands.

A>MTXL
ROM 5
USER DIR
USER RUN "F:TOADO.RUN"

Loading virtual tapes

Prior to switching to MTX BASIC, you can use SDPTAPE to prime virtual cassette tapes with the contents of .MTX files. From CP/M :-

A>SDPTAPE QUAZZIA.MTX 0
A>SDPTAPE SNAPPO.MTX 1
A>MTXL

Then the usual MTX BASIC LOAD command can be used to load it :-

LOAD "QUAZZIA"

Running SDPTAPE with no arguments lists bytes 1-15 of the virtual cassette in each slot, which is handy, as these are the names you will need to LOAD from MTX BASIC. These names do not necessarily agree with the names of the .MTX files they were loaded from.
