An [[8bit Printer Ports|8bit Printer Port]] DIY extension from german magizine German magazine [[CPC Schneider International]] (issue 12'85, page 64).Connects Printer Bit7 to Joystick1 Joystick 1 Select signal (joystick port pin8).
This solution isn't too recommenedrecommended. Some drawbacks and problems are:
* Joystick Select is an open-collector output, so HIGH levels may be unstable (this could be fixed by an additional pull-up resistor).
* Bit7 may tend to be HIGH by default, so printing normal text won't work with normal software that doesn't support the mod (the schematic includes a switch to disable the mod manually).
== Note ==
Some years later the same magazine (renamed to [[PC Amstrad International]], issue 8/9'91, page 69) released another 8bit printer mod: This newer (and better) solution uses PPI.Pin12 (same as the [[Happy Computer 8bit Printer Mod]]).
