The device code bytes 0,1,2: 0x1e, 0x93, 0x7 were read
from parallel port 0x3bc and indicate the following:
You have connected an ATmega8
The device was made by Atmel

11100001 are the fuse bits read from an ATmega8
0xxxxxxx - BODLEVEL 4V (default 2.7V)
x0xxxxxx - brownout detection enabled
xxSUxxxx - reset delay, datasheet p28
xxxxCKSE - clock select, datasheet p24

1011001 are the high fuse bits read from an ATmega8
0xxxxxx - WDT always on
x0xxxxx - serial programming enabled
xx0xxxx - CKOPT max, datasheet p24
xxx0xxx - eeprom not erased
xxxxBZx - boot size, datasheet p215
xxxxxx0 - reset at boot loader, p204
Note: RSTDISBL is 1

111111 are the lock bits read from an ATmega8
xxxx11 - no lock
xxxx10 - write protected
xxxx00 - read/write protected
BTLKxx - Boot lock, datasheet p116

0xb0 is the calibration byte read from address 0x00
