Zaccaria Display 6 digit 1° Generation


Here my solution about first generation Zaccaria Pinball display.

It can be 6 digit plus 1 dummy digit for some conversion kit (like Horror from PinballShop), easy to remove thanks to slot hole.

All resistors and capacitors can be SMD or PTH.

Schematic and Interactive BOM (Revision 2):

Issue on Rev 2:

Power supply for dummy digit are inverted: need to cut +5V and GND and invert power

Work with cd4724 need to add some components. Need to use 4028 and 4042.

Need some question? Want try this solution but don’t have the correct instruments?

Contact me, it will be a pleasure to help you.
