MegaROM

419 bytes added, 12:48, 24 May 2011
The MegaROM is compatible with all 464, 664, 6128, 464+ and 6128+ and can be used to host standard ROM images such as [[AMSDOS]], [[BCPL]], [[FutureOS]], [[MAXAM]], [[Protext]], [[Utopia]], [[VDOS]], [[XD-DOS]].
 
CPC Specific Limitations:
 
* CPC464/664 - The 464 and 664 only scan and initialise ROMs 7 to 0 at start-up. ROMs 15 to 8 are only accessable if manually initialised.
* CPC6128 - Classic CPC6128 can not overwrite the internal ROM7 with an external device, to make use of the external ROM7 the CPC must be modified to allow the internal ROM7 to be disabled (eg: By adding a switch to the internal ROMs Chip Enable pin)
 
The MegaROM fully decodes the Address and Data buses, so it should not clash with any other official expansions installed in parallel or plus cartridges.
