- ReadPlusD reads an MGT (Miles Gordon Technology) PLUS D 3.5" double-sided
- diskette on any Amiga. MGT PLUS D diskettes are used on Sinclair Spectrum
- computers. This is useful for transferring Spectrum programs to the format
- required by the Spectrum emulator on the Amiga.
-
- ReadPlusD requires messydisk.device (supplied with MSH on Fred Fish disk 382)
- in the devs: directory.
-
-
- CLI usage: ReadPlusD disk-unit-number [directory-entry-number output-file]
-
-
- The disk unit number should be an integer in the range 0..3 corresponding to
- the drive (DF0:..DF3:) containing the PLUS D diskette.
-
- If given just the unit-number, ReadPlusD displays a directory of the disk.
-
- If you also give a directory entry number and an output file name, ReadPlusD
- converts a 48 kbyte snapshot file to the format required by the Amiga Spectrum
- emulator. The output is written to the given file name.
-
- Note that you specify the number of the directory entry (an integer in the
- range 1..80), not the name of the input file. If the file is not a 48 kbyte
- snapshot file, ReadPlusD displays an error message.
-
-
- Examples:
-
- ReadPlusD 2 get a directory of the PLUS D disk in DF2:
-
- ReadPlusD 1 17 RAM:TRON convert the 17th file on DF1: to RAM:TRON
-
-
- Known bug:
-
- ReadPlusD always sets the z80 interrupt mode to 1. A few Spectrum programs use
- interrupt mode 2. If a converted program doesn't run and you suspect it might
- use mode 2, try patching the byte at offset 25 in the output file to be $02.
- Use a binary file editor like, for example, NEWZAP. The byte you patch is
- actually the 26th byte in the file (because the 1st byte is at offset 0), and
- it will always be $01 to begin with.
