Hello,

See my Whirlwind thread on pinside for details on my alphanumeric controller. This was the first alphanumeric rewrite game. I had a stock of the boards but they are sold out currently as interest wained on them. The controller board recreates the missing logic needed for the proc to drive the displays on system 11 and before. This is basically the logic williams added to the display board when changing from system 11 to wpc. They only used it in 2 games though (funhouse and bop) before ditching and going to dmd.

I also believe it will drive williams flavour segment displays back to system 6 with some cable tweaks. There is also an updated scoredisplay class that myself and scott worked on to improve the system 11 display interface and help take care of some of the mundane display controlling aspects.

For Bally segment displays and what's in use on scotts total annihilation project, this is the display controller part of my custom pinball controller boardset. See the top arduino nano in this pic

I think scott made his own breakout board for it as wasn't using the cabinet wiring. Cant 100% remember on that, but there are stock breakout boards i can supply to interface from the arduino nano part and the cabinet wiring if you only want to use the display part of my controller.

I would make a dedicated display specific breakout for this myself for true plug and play on custom projects, but again the interest isn't there currently to make it worth my while. Maybe this will change. My efforts for early Bally game love go on my full board set

Yep were working on getting things powered and wired up at the mo. The central system and code used is the same that controls displays on my controller boards and on scotts total annihilation prototype. Though a partially populated controller board could have been used here, the adapter board fits better here i think, is smaller and gives more flexibility for connection.

Once power up and connected to the original wiring the displays should spring to life and display the test boot up pattern of all zeros. Then we'll tackle the communication from the game code.

Great to see the displays light up correctly with the boot up pattern finally!

Lots of back and forth with info to get here.

For others interested in how the low voltage led displays get power the info is here:

+5V is pin 20 on each display. The wire colour is Green/White (45). It is fed from power driver board connector J3 - pin 17
GND is pin 13 on each display. The wire colour is brown (60). It is fed from the power driver board connector J3 - pin 20

The high voltage power for the original displays is pin 1 and is +190v. This is also fed from the power driver board J3 connector - pin 8 and is the wire colour is red.
