- Special, specialp, lik, erik: At the first prompt, press Enter for the Monitor. All other keys just beep.
- Specimx: Press Enter to go into a ramdisk File Manager. Press F3 to load a tape (which errors).
If you had loaded a disk, press F6 to boot it.
- Specimx -bios 1 and 2 don't set a colour, so a default has been chosen instead of a black screen.
- Specimx -bios 1 lists a number of programs on the ramdisk, but most of them don't work.
