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 $2000 and patched it there. The reader was supposed to use a monitor to save the new ROM then. The ROM is simply burned to an 8k eprom and added to the C64 using a kernal switching board then. Exos does not require a change on the drive ROM.
REX Datentechnik released Exos v3 as a cartridge (order number 9805).
V-DOS by Völkner Electronic (order number 9716) was created by J.Schemmel as well and is said to be the same as the Rex Datentechnik cartridge release.
Functionality
- Fast serial load (can be disabled)
- LOAD"$",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
- Joe as hacker of the V4 Exos version describes the applied changes as:
- changed colors back to commodore-blue and reset message closer to original C64
- jsr $fd15 doesn't write vectors to ram at $fd30
- fixed bug preventing that load"$" prints on screen instead of loading to basic (a correction printed in a 64'er issue)
- autostart after reset on write-protected floppies (the only new feature)
- Exos is known to be not the most reliable speeder due to the increased speeding of the stepper motor within the drive
