Changes

The same chip was used within the CPC464 and CPC6128.
In CRTC terms it operates almost the same as the CRTC within the Plus ASIC. The following information relating to the pins of the IC was tested and verified by Gerald:
==L4N6 pin==
- ROMDIS act as the DDI ROMDIS as it is active even during ram access
10943-0
==Bonus==
- on the following page, Gate Array and ASIC Pin-Outs - CPCWiki, pin 35 and 36 are undocumented.
