Hello
Has anyone successfully used Motorola Cracker to read MC68HC705B32 microcontroller?
I'm trying with this schematic and Motorola Cracker 6.2 without success.

Motcrker not read secured chip but boot time can erase mcu eeprom
If erase can write new dump
check your connections pins "4mhz osc"boot mcu select 68hc05 or 05b32 write the new dump
