R Reset then load DOS from floppy S a b c Save memory to tape (a = start, b = end, c = exec) KEYBOARD - When started, the Lock is engaged, so numbers appear as symbols. Hitting Shift will unlock this and return the keyboard to normal. - To use the natural keyboard, hit > (or some other shifted character), then proceed as normal. - To paste, use the emulated keyboard and hit Shift, then do the paste. - The monitor command-line cannot handle the arrow keys or Del correctly. - It is thought that the BASIC cartridge has better keyboard handling.
