Bally MPU gezocht
Iemand nog een MPU liggen op overschot voor een Bally flipperkast type Dolly Parton, Evel Knievel, Harlem Gmobetrotters ?? Liefst in werkende staat natuurlijk.

Re: Bally MPU gezocht
Die MPU's van Jos waren spijtig genoeg allemaal early mpu's ... (Evel Knievel bijvoorbeeld).
Ik zoek er dus eentje voor type Harlem Globetrotters, Dolly Parton, ...
Grtz,
Lieven

Re: Bally MPU gezocht
Als dat een AS-2518-17 dan hed je die kunnen aanpassen naar een AS-2518-35.
Jumpers /cuts en nieuwe roms branden en je kan verder.
Pinrepair
Mod4: 2732 EPROMs at U2,U6 on a Bally -17 or Stern M-100 board.
AKA Converting a Bally -17 or Stern M-100 to a Bally -35 MPU.
This modification allows a Bally -17 or Stern M-100 MPU board to be used on any Bally game up to 1985. It doubles the amount of ROM space the older MPU board can use, and essentially makes a Bally -17 or Stern M-100 MPU board a Bally -35 MPU board. Note you can not use a -35 Bally board in a Stern games requiring a M-200 MPU (these boards have two 5101 RAMs instead of one as used on a Bally -35 MPU).
In addition to the jumpers listed above (1-2, 3-5, 6-7, 8-10), you must also make the following cuts and jumps to use this configuration.
Make sure jumpers E1-E2, E3-E5, E6-E7, and E8-E10 are in place.
Double check jumper E3 connects to E5.
On the solder side, cut the trace that runs to U2 pin 21.
On the component side, cut the trace that runs to U2 pin 18. Best place to do this is where the trace passes between sockets U2 and U3. Use your DMM set to continuity to help figure out the trace to cut.
On the solder side, jump a wire from U2 pin 18 to U2 pin 12.
On the soider side, jump a wire from U2 pin 21 to U9 (CPU) pin 24.
On the solder side, cut the trace that runs to U6 pin 21.
On the component side, cut the trace that runs to U6 pin 18. Best place to do this is where the trace passes between sockets U6 and U5. Use your DMM set to continuity to help figure out the trace to cut.
On the solder side, jump a wire from U6 pin 18 to U6 pin 12.
On the solder side, jump a wire from U6 pin 21 to U2 pin 21 (this connects both U2 and U6 pins 21 to U9 pin 24).
On the solder side, cut the trace that runs to U17 pin 2.
On the solder side, cut the trace that runs to U18 pin 4.
On the solder side, jump a wire U17 pin 2 to U18 pin 4.
Of wil je een originele?

Re: Bally MPU gezocht
Aangezien ik geen van beide heb en er eentje wil aanschaffen dan toch liever een originele ...
Die zouden veel talrijker moeten zijn dan de early versie ...
