Easter Eggs
In 128 BASIC, run "copy randomize" then quickly hold the keys C, J and L after pressing ENTER. It will display a colourful full-screen message that says:HELLO |
Remarks
| Essentially a ZX Spectrum 128K with different case and keyboard, built-in 3-inch floppy disk drive, +3DOS and CP/M support, 32Kb of ROM and 128Kb of RAM. A small hardware revision (to fix audio output clipping problems and remove support for internal tape drive) later brought the +3B (not a completely separate model). You could also buy the special set, ZX Spectrum +3 Action Pack. The package included the book ZX Spectrum +3 Manual. |
