Changes
472
,ROM information
As there were no space for a new chip, Amstrad designers took off one of the ROM chips, and put it in a daughter board, along with the 4164 chip. Wires connected pins at the ROM from the daughter board to the corresponding pins on the main board. The wires were hard enough to make difficult to turn the daughter board over and reveal the trick: no wires were connected from the DRAM chip, to the main board. Even supply pins were not connected!!
While based on the CPC 464, at least some of the 472 got the ROM v2 with [[Locomotive BASIC]] 1.1, which normally was built into the CPC [[664]].
After the rule changed there was also a CPC 472 with non-spanish keys available for a very short time. The CPC 472 with spanish or british keyboard is very very rare.[[Image:Amstrad 472 detail motherboard.jpg|thumb|right|200px|Motherboard close-up, showing the "8KB" extra memory, next to the 40037 ROM chip.]]
