This is  a cartridge designed by Maciej Witkowiak that simulates the Commodore 1551 disk drive used on the Commodore Plus/4 and C16/116 machines (264 series). It can also be used as a paddle replacement for a real 1551 drive, or for use with the Pi1551 drive. The case is now modified to accept the ribbon cable for the Pi1551 as shown.

Built using a black or blue PCB with ENIG 2 micron gold finish and including a 256 or 512 EEPROM.
The case is a modified redux 264 style cart and is now redesigned to accept the Pi1551 drive.
An EEPROM is supplied by default burned with the Parobek multi-fast-loader v1.1 utility and DOS wedge ROM.
This autoboots on switch on.

The two buttons on the top/back of the device move between disks in a directory for multidisk games or applications.

This cart is incredibly fast and has several games as well as a GEOS conversion to take advantage of the fast load times.
A lot of other software will also work IME, especially copy ripped games or single prg format files (or your own load/save programs of course) but most fastloads or copy protected software may not, unfortunately.
There is a Pi1551 project on github in early stages, a modified Pi1541 that works with this paddle and should give better compatibility.

Some features:

  • DLOAD and DSAVE support for files
  • support for disk images (D64, D71, D81, D80, D82) as subdirectories
  • standard Kernal transfer at about 3100b/s (a little bit less than JiffyDOS 1541, twice as fast as 1551 (1600b/s)); fastload at about 9300b/s (23x as fast as 1541, about 6x as fast as 1551), with patched Directory Browser v1.2; on par with DolphinDOS
  • fastload booter embedded in the flash, available at all times as * file will load and run BOOT.T2SD file from root directory; this can be any file that can run from BASIC; Directory Browser patched with fastload protocol is recommended
  • CBM DOS disk commands: CDRSMDRDIUIUJ

Some of the games patched with fastload boot: Alpharay, Bards Tale III, Dragon Wars, Ghosts 'n' Goblins, Giana Sisters, Lemmings, Lykia, Pets Rescue, Prince of Persia, Turbo Outrun, Spellbound Dizzy...
