need schematics for Aristocrat slot with MPU

(1/2) > >>

Badbaud:
The only info I have on this machine is the power supply voltages and where the test points are.

They all check good.

The MPU board uses a 6502 and some 5101 RAM's.

Replaced the dead battery and did RAM clear start up procedure but display and game play still not working.

edtruman:
Are you working on an Aristocrat/IGT Esprit ?

I have seen Esprit schematics floating around on the retired NLG site

Badbaud:
Ya but I am not a contributing member so that area is closed to me.

I'm retired, no credit cards, no checking account, couldn't contribute even if I wanted to.

Paul:
Which Aristocrat do you have?

Badbaud:
Sorry for the delay. The model number on the IGT sticker is R80CB0.

It is a 3 reel slot with the CPU and I/O board in a metal rack behind the top glass.

Not on the lower left like I have seen in the past.

The game is completely dead but all power supply voltages read correct.

Replaced the battery, reseated all chips with no help.

Crashed the RAM and tried again but still no luck.

Checked all 3 legged semiconductors on the I/O board and they all check good.
