NOTE:
NOTE:
Before programming the PROM using an MC68HC05PGMR PCB in
standalone mode, the user should ensure that:
If the V
MCU device will suffer permanent damage.
Once those conditions are met, the user should take these steps before
beginning programming:
No PROM MCU should be inserted in or removed from its board socket
(U2 or U3) while V
1. Remove the V
2. Set switch 1 in the OFF position (removes V
3. Place the programmed EPROM in socket U1.
4. Insert the erased PROM MCU device to be programmed in the
5. Set switch S2 in the RESET position.
