29======= hprotr8a ===========
30Loops during boot displaying an error message related to low power supply voltage.
31We need to emulate the ADM695AN chip (Microprocessor Supervisory Circuits) in order to properly boot the device.
32
33======= hprot2r6 ===========
34There are unhandled memory writes at 0xE000 and 0xA000
35
36LCD commands are sent, but nothing shows up on screen.
37The commands sent are supposed to display the message:
38
39"*Pouca  Energia*" (LCD cmds range: 80-8F)  (cmds logged but not displayed on screen)
40"*  no Sistema  *" (LCD cmds range: C0-CF)  (cmds logged but not displayed on screen)
41
42which means something like "too little energy for the system to operate".
43We need to emulate the ADM695AN chip (Microprocessor Supervisory Circuits) in order to properly boot the device.
44
45Infinite loop is reached at address 0x7699
46======= hprot1 ===========
47
2348  There seems to be an eeprom or a realtime clock placed at U2 (DIP8):
2449  pin1 -> 8031 pin 14 (T0: Timer 0 external input)
2550  pin2 -> crystal at X2 (labeled 32.768)

152There is a set of 3 jumpers that switch the communications circuitry between a

155It seems that all three jumpers must select the same configuration:
156eighter differential bus or RS232.
157And I don't see yet how this could affect the emulation of the device, so, for now, I'll
158simply leave this note here but not actually include this details in the driver code.
