bas2fx70.zip - file size: 13kB, source and executable, DOS and Windows (in a DOS window)

This utility converts the Casio FX-700P BASIC programs in ASCII format to the tape image format (file transferred through the serial port using the tape interface with the software version 27).

Usage: bas2fx70.com program.bas > outfile.txt

• Relational operators <>, <= and >= are converted to equivalent Casio codes 0x0F, 0x0B, 0x0D. Forms ><, =< and => are accepted as well.
• Numerical constants in exponential form can be noted as 1.23E5 or 5.67E-8, the E and E- strings are replaced with equivalent Casio codes 0x0F and 0x0E.
• String PI is converted to the Casio code 0x1B.

list700.zip - file size: 10kB, source and executable, DOS and Windows (in a DOS window)
list730.zip - file size: 10kB, source and executable, DOS and Windows (in a DOS window)

These programs display the contents of a tape image saved by the FX-700P or FX-730P calculator (through the serial port using the tape interface with the software version 27). Files with variables (saved using PUT) aren't supported.

Usage: list700.com infile.txt

The output can be redirected to a file or a printer.

pgm2b74.zip - file size: 13kB, source and executable, DOS and Windows (in a DOS window)

This utility is designed for the Texas Instruments TI-74 pocket computer. It does the opposite of what TIC74 program (supplied with the PC-Interface) does: Converts the compressed BASIC .PGM files to plain ASCII text format.

Usage: pgm2b74.exe infile.pgm [outfile.b74]

The output file name is optional, by default it will be the same as the input file name with the extension changed to .B74.

md100img.zip - file size: 8kB, source and executable, DOS and Windows 95/98 (in the command line mode)

This program can read and write the MD-100 floppy disk image.

Usage: md100img.com command disk_image_file

Examples:
- reading the disk contents to the image file GAMES.BIN: md100img.com r games.bin
- writing the image file DATABASE.BIN to the disk: md100img.com w database.bin

The program will not work under Windows 2000, NT, XP, nor is guaranteed to work under Windows 95/98 with GUI loaded.

hd61_dis.zip - file size: 13kB, source and executable, DOS and Windows (in a DOS window)

Simple disassembler for the HD61700 microprocessor used in the Casio PB-1000 pocket computer, supporting roughly the same list of undocumented instructions as the version 0.20 of the (much more powerful) DA61 Disassembler. The program originated as a study for an emulator project.

Usage: hd61_dis.com infile.bin [address] [/w] > outfile.txt

• The optional starting address can be specified as a hexadecimal number without any prefixes. If omitted, a default value 0000 is assumed.
• The optional switch /w selects the 16-bit (word-size) memory access (applicaple for the microprocessor internal 16-bit ROM). If omitted, a default 8-bit (byte-size) memory access is assumed.
