The '''6 MHz''' CPC is a [[DIY]] hardware modification which allows to run the [[CPC6128]] with a CPU speed of 6 MHz instead of the usual 4 MHz.
== Technic ==
The 16 MHz crystal of the CPC is replaced by a 24 MHz crystal. Both crystals should kept on the main board, but a switch (a DPDT type, switching both lines to both crystals is recommended) selects between them. Keep the wiring tidy and very short. You have to select the CPU and bus speed before you switch on the CPC. Switching the speed while the system is switched on is not advised.
'''If you attempt this modification, it is at your own risk. None of the authors of this article can or will be held responsible for any damage to your CPC as a result of your DIY work.'''
