OBattler	1d4fed2110	Improved 8042 (AT and PS/2 keyboard controller emulation), no more hacks, split into various devices depending on vendor (generic, AMI, IBM (MCA), Quadtel, Toshiba), and fixed several commands - hopefully fixes all existing AT+ keyboard problems (such as incorrect scan codes on some machine under some circumstances); Fixed a bug in the SMC FDC37C932 emulation, fixes the FDC on the two Acer machines; Re-added some Acer-specific I/O port handlers, fixes entry into CMOS Setup on the two Acer machines.	2018-01-04 07:44:33 +01:00
OBattler	9b2705eb9f	Inverted the operation of the OPTi 495 A20 control bit and made the AT keyboard controller (8042) as well as memory default to A20 off - makes both the MR 386 DX and the Award 386 and 486 clones work correctly; The Amstrad MegaPC now correctly initializes the internal Paradise WD90C11 graphics card, making the machine work again.	2018-01-04 01:57:55 +01:00
OBattler	412ae3726b	Implemented the OPTi 495 A20 state switch (register 0x27 bit 7), fixes the A20 gate stuck error.	2018-01-02 21:35:25 +01:00
waltje	7c67e867c8	Major commit, cleaning a lot of old stuff. IBM.H is gone, video stuff re-organized. Keyboard stuff reorganized. Machines that have their own video, mouse and/or keyboard now have all this in their machine file. Fixed and other cleanups here and there.	2017-11-05 02:00:50 -05:00
