My Tempest Multigame HSS isnt saving anything. I had Maxstang installed multigame and new chip ER2055.

Game isnt set to demo mode (plays up to 9 level). Requries to play credits (not setting freeplay). Still cant save?

Right now Dip Switch set to

K10/11 (4 dipswitch) All set OFF
L12 (8 dipswitch) All set ON
N13 (8dipswitch) All set OFF

Still cant save any score??

Advise would be appreciated!

Not sure if I should CAP the board to see if it fixes theproblem. the tempest board looks like new..

I am not sure about the multi kit, but a normal Tempest uses a ER2055 chip on the board to save high scores, as well as Centipede, Dig Dug, Red Baron....
I had to replace mine and it now saves.
Again not sure how Clay's kit works.

I'll chime in here as the game belonged to me before Billy. I tried replacing the ER-2055 with a "new" one with no change. I also checked to verify the -28 volts on pin 14 of this chip and it seemed fine. It's possible my replacement ER is bad, but I did try both another used one and switching out the entire AUX board and the scores still didn't save. Anyone know what's upstream of the AUX board that we should be checking for HS score save?
