bbc.cpp: Reimplemented the addressable latch with LS259 device.
- Added 32K ROM slots in B+ and Master variants. - Use bankdev to switch IO/ROM in Master. - Use ram_device instead of ROM_REGION for RAM. - Added I2CMEM device for PCD8572 in Master Compact. - Corrected sound device SN76489->SN76489A.

The addressable latch
|
||||
This 8 bit addressable latch is operated from port B lines 0-3.
|
||||
PB0-PB2 are set to the required address of the output bit to be set.
|
||||
PB3 is set to the value which should be programmed at that bit.
|
||||
The function of the 8 output bits from this latch are:-
|
||||
|
||||
B0 - Write Enable to the sound generator IC
|
||||
B1 - READ select on the speech processor (B and B+)
|
||||
R/nW control on CMOS RAM (Master only)
|
||||
B2 - WRITE select on the speech processor
|
||||
DS control on CMOS RAM (Master only)
|
||||
B3 - Keyboard write enable
|
||||
B4,B5 - these two outputs define the number to be added to the
|

start of screen address in hardware to control hardware scrolling:-
