Searching for Personality Eproms E2404-10-9 (only displays 7.....6.)

[Michu]

Hi Friends,

i picked up an faulty E2404-10-9 (3-Wheel) Slot, and i nothing knows about his History.

Model: E2404-10-9  (3-Wheel)
MPU: AS 2978-7
M1: E755-49  M1 5.651 SDS 11-2-87
M2: E755-50  M2 5.651 SDS 11-2-87
M3: E755-134 M3 5.656 SDS 11-2-87
P1: Black Sticker Unknown 2716
P2: Sticker unreadable, also unknown 2732

The Pre-Owner has removed the leaked Battery, but doesn´t really cleaned the pcb.

Now i picked up this beautyful Machine, and try to give him a second life.

I cleaned the PCB, IC-Pins and Sockets, measured and repaired the corroded soldering junctions.
Removed R62 (100ohm charging Resistor) and added an 1N4007 and a 18650 Battery.

The Machine starts directly with Error "7.....6."
If i remove P1+P2 it starts with Error " .....6."

I think, it could be a wrong P1 and/or P2 Epromdata, if someone has changed this Eproms before.

If someone have these Eproms and the checksums of it, i could verify my Eproms, if they are correct.
Or can i do a "MPU-Function-Test" with an other 3-Wheel Chipset ?


I appreciate any Help!
