Description
QuickDisk BASIC is a BASIC extension that is available with the addition of a Quick Disk Drive, an intermediate storage system between tape and diskdrive.
It comes in a 8kB ROM, that has its own 2kB SRAM, so the memory space available for MSX-BASIC is not decreased with the addition of a Quick Disk drive.
This extension can be used on any MSX generation, but for MSX turbo R machines, it's limited to the Z80 mode (what implies to boot while pressing the "1" key until you can hear a beep).
Versions
There are 3 versions of this extension:
- Version 1.00, found in Daewoo devices
- Version 1.10, found in Casio and Sanyo devices
- Version 1.11, found in Philips devices
Instructions (general info)
QuickDisk BASIC extends the OPEN and CLOSE instructions and adds 11 new instructions, most of them are inspired by standard instructions or Disk BASIC instructions.
7 of these new instructions are linked to function keys, whose content is redefined.
Note: CALL can be replaced by the character underscore (_). A space is not required after this character. See CALL for more info.
