The Triton Quick Disk Drive is a product that allows 2.8-inch floppy disks to be read on the Commodore 64,[1] ZX Spectrum,[2] MSX,[3] Mattel Aquarius[4] and Dragon 64[5] home computers. The product was released for sale in the mid-1980s.
The disk drive can be used with Hitachi Maxell 2.8-inch double sided floppy disks, with a capacity of 144 kilobytes non-formatted and 100 kilobytes formatted. Each side has 20 sectors of 2.5 kB[1][2] written in a spiral pattern instead of the more usual circular tracks.[2][4] A maximum of 20 files can be saved on each side of the floppy disks.
The data transfer rate is up to 100 kilobits per second.[1][2][4] The disk drive measures 250 x 225 x 65 mm, weighing in at 3.2 kilograms.

- @Dn
- @Format
- @Dir
- @Save
- @ASave
- @Write
- @Load
- @Run
- @Aload
- @Kill

If something goes wrong, 14 different error messages will give indications about what may have happened.
Triton and Spectrum
For use on the Spectrum computer, the controller/interface box contains an EPROM with an additional operating system, Spectrum T-DOS, adding various new commands to the computer:
- Format *n
- Cat *n
- Save *n;b;'file name'
- Save *n;m;'file name; startadd; endadd
- Load *n; 'file name'
