ExOS was developed by J.Schemmel and released by the german paper magazine 64'er in the December issue of 1986. It was published as a ROM patch which copied the original C64 Kernal to $2000 and patched it there. The reader was supposed to use a monitor to save the new ROM then. The ROM is simply burned to an 8k eprom and added to the C64 using a kernal switching board then. ExOS does not require a change on the drive ROM.

REX Datentechnik released Exos v3 as a cartridge (order number 9805).

From the manual:
CTRL + K Display drive error channel
CTRL + O OLD function
CTRL + U Enable saving RAM under Basic ROM
CTRL + S Transfer program into RAM floppy
CTRL + L Transfer program from RAM floppy
CTRL + V Swap program with program in RAM floppy
CTRL + F Increases stepper speed in drive
CTRL + X List Basic program from current position
CTRL + Z List Basic program 50 lines before current position
CBM + F1 and CBM + F3 Transfer screen RAM to RAM drive
CBM + F5 and CBM + F7 Transfer screen RAM from RAM drive
CTRL + A Disable fast loader
F1 / F3 / F5 / F7 LIST / RUN / LOAD / DIRECTORY
F2 / F4 / F6 / F8 SYS 32768 / SYS 4096 * 12 / SAVE" / CLOSE7:OPEN7,8,15"
CTRL + Reset Avoid cartridge start and reset protection (SpeedDOS reset)

V-DOS by Völkner Electronic (order number 9716) was created by J.Schemmel as well and is said to be mostly the same. (Dump missing...)

Functionality

  • Fast serial load (can be disabled)
  • LOAD"$",8 redirected to screen output on direct mode
  • Start and end address output
  • OLD function
  • RAM floppy functions
  • some extended LIST support
  • modified reset routine (hold CTRL during reset)

Notes

  • v3 to v4 changes are not yet documented
  • ExOS is known to be not the most reliable speeder due to the increased speeding of the stepper motor within the drive
