NOTE: Even though the MAME/MESS project has been adopting a non-commercial additional licensing clause, I do allow commercial usage of my portion of the code according to the plain terms of the GPL license (version 2 or later). This is useful if you happen to use my code in another project or in case the other MAME/MESS developers happen to drop the non-comercial clause completely. I suggest that other developers consider doing the same. --Felipe Sanches
Changelog:
2014 JUN 13 [Felipe Sanches]:
* new derivative "CARD I PCB rev.08A"
* new derivative "CARD II PCB rev.6"
* fixed LCD rendering (now both lines are displayed properly)
* inverted logic of the inputs so that now we can navigate the menu
2014 JAN 03 [Felipe Sanches]:
* Initial driver skeleton
* Address lines bitswaping
* LCD works. We can see boot messages.
* Inputs are not working correctly
TO-DO list:
======= hprotr8a ===========
Loops during boot displaying an error message related to low power supply voltage.
We need to emulate the ADM695AN chip (Microprocessor Supervisory Circuits) in order to properly boot the device.
======= hprot2r6 ===========
There are unhandled memory writes at 0xE000 and 0xA000
LCD commands are sent, but nothing shows up on screen.
The commands sent are supposed to display the message:
"*Pouca Energia*" (LCD cmds range: 80-8F) (cmds logged but not displayed on screen)
"* no Sistema *" (LCD cmds range: C0-CF) (cmds logged but not displayed on screen)
which means something like "too little energy for the system to operate".
We need to emulate the ADM695AN chip (Microprocessor Supervisory Circuits) in order to properly boot the device.
Infinite loop is reached at address 0x7699
======= hprot1 ===========
There seems to be an eeprom or a realtime clock placed at U2 (DIP8):
pin1 -> 8031 pin 14 (T0: Timer 0 external input)
pin2 -> crystal at X2 (labeled 32.768)
pin3 -> ?
pin4 -> GND
pin5 -> ?
pin6 -> 8031 pin 5 (Port 1 bit 4)
pin7 -> 8031 pin 4 (Port 1 bit 3)
pin8 -> VCC

There is a set of 3 jumpers that switch the communications circuitry between a

It seems that all three jumpers must select the same configuration:
eighter differential bus or RS232.
And I don't see yet how this could affect the emulation of the device, so, for now, I'll
simply leave this note here but not actually include this details in the driver code.
