== GX4000 Differences compared to 464 or 6128 Plus ==
* The master clock is 39.9Mhz (approx) instead of 40Mhz for the 464/6128 Plus. The Arnold V specification indicates this is to give a better picture. This means the GX4000 is 0.25% slower than a 464 or 6128 Plus but should have a better picture.
* The pause button on the GX4000 is mapped to the P button on the CPC keyboard. Other than this the 2 digital joysticks are connected, all other keys are not connected.
* There is a difference in the wiring schematics on the ADC inputs where the ASIC senses the computer configuration.
* The following are not connected on GX4000 so the associated inputs are not defined (possibly high):
* Printer (data and strobe)
* Keyboard lines 0,1,2,4,5,6,7,8
* FDC
* FDD motor
* Cassette read, write, motor
* The signals /ROMEN, ROMDIS, /RAMRD, RAMDIS, CRTC CURSOR, EXP, Printer BUSY
