The model 1B1110/evo replaces and is fully compatible with all previous models 1B1110, 1B1110/0, 1B1110/1, 1B1110/1a which are used in all the 1st generation Zaccaria pinball machines.
The old CMOS 5101(IC7) and 2101(IC8) have been replaced by a 6264 sram.
This board includes a new feature which allows to erase and clean the memory.
Early G1 games have a flaw in the eproms which may lead to instable and corrupted memory values.
We have developed a special feature in order to fix this problem and clean the memory to program all the parameters in the correct way.
The board is sold without CPU Signetics 2650A.
If you have an old defective CPU board you can remove the 2650A from the old board and install it on the new board**
** The first version of the Signetics 2650 microprocessor (white ceramic model) may not be compatible with this MPU board, check it before.
This board doesn’t use eproms anymore, just select the right game model through the dip-switch.
