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).

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
