+
+This file describes the technical specs I found out, mostly by
+trial and error.
+
+Card: Hyundai HGC-1280 Video Controller.
+Monitor: Hyundai HMM-1900E 19-inch High Resolution Monochrome Monitor.
+
+Resolution (officially) 1280x960x1bit, max. 1280x1024.
+Max. virtual width 1472.
+
+2 modes:
+Mode: emulating Hercules
+	(primary address)
+	Ports 0x3B9 - 0x3B7
+	Mem 0xB0000 - 0xBFFFF (64kBytes)
+Mode: 'graphics mode only'
+	(secondary address)
+	Ports 0x390 - 0x397
+	Mem 0xC8000 - 0xCFFFF (32kBytes)
+
+The following might be valid only for the card jumpered to the secondary
+address.
+
+Mem window 0xC8000 - 0xCFFFF (32kBytes) is 2 separate read/write banks.
+(On primary address: first Herc bank 0xB0000-0xB7FFF = 2 banks)
+
+Visible lines are 1280 pixels (160 Byte) long. On the right side, further
+32 bytes are read/write. By changing one of the regs, the visible area
+can be shiftet right, but only by 24 bytes, i.e. to show pixels 192 - 1472.
+This gives a virtual width of 1472.
+The lines are aligned to 256 bytes.
+Byte 196 - 255 are read/write, but they mirror parts of the visible line,
+so they must not be written.
+
+The video mem is divided in 16 banks to 16kB each. 2 of these banks can
+be banked in the mem window.
+
+Register level programming:
+The HGC-1280 (in 'graphics only' mode) is programmed like a Hercules:
+Base: 0x3B0 (primary) , 0x390 (secondary)
+base+0	index port
+base+1	data port
+base+8	control port
+base+10	crt status port
+base+15	config port
+
+registers: write register number to index port, read or write data from/to
+data port.
+register number: 0 to 63.
+
+Registers:
+
+default for 1280x960:
+[cf. bdm2/drivers/hgc1280/hgc1280HW.h: hgcRegsGraf1280x1024[HGC_NUM_REGS]]
+changes for 1280x1024:
+reg 52:  61 -> 65
+reg 54:  61 -> 65
+reg 46: 195 -> 191
+
+Hercules registers (0 - 18) are unused in 'graphics only' mode.
+reg: def. for graph. - description
+----------------------------------
+39: 213 - mem organization
+40:	- scan line timing
+41:	- dto.
+42: 138 - inc => displayed line starts 2 bytes later
+43:  90 - dec => displayed line ends 2 bytes earlier
+44:  33 - vert. timing
+45:  16 - moves visible area horizontally -> panning;
+	  dec => 2 bytes to the right.
+46:	- vert. timing/position
+47:	- vert. screen position in scan lines
+48:	- ??
+49:	- ??
+50: 224	-
+51:
+52:	- vert. timing
+53:	- vert. pos. within mem
+54:  61 - bottom length in steps of 16 scan lines
+55:  79 - 79->80 => bottom + 60 lines
+56:	- don't set bit 4!! - total hang!
+57,60,63 - not writable, zero (?)
+61	- fixed 85 (?)
