Sorry, not sure on the board question.

First thing I would do is replace all of the hacked IDC connectors and see where things stand (that needs to be done even if you eventually have to replace the board).

I second that, not really a major task either. Just curious, has that board seen any water? By the looks of the retaining screws I would be suspect of water damage.

+3 on the connector swap first.

Looks like a really simple board that doesn't have any visual problems (burned components, etc). The single IC looks to be in a socket already so it should be easily repaired if it is not working after the connector replacements.

Williams made four different versions of this board and by all accounts, they were all the same save for which plugs were populated on the board.

All had the power input J1 plug. The rest are populated and used as follows:

A-13091 - Used in FH
J2,J5 populated

A-13091-1 - Used in HSII, FT & CFTBL
J2, J3 populated

A-13091-2 - Used in IJ, Hot Shot, Slugfest
J2, J3, J4 populated

NOTE: In the IJ parts listing on IPDB, the P/N listed for this board is A-17042-3, but if you look at this photo, you'll see the same plugs populated:

In both the IJ operations manual and Williams parts manual it's listed as A-13091-2:

A-13091-3 - Used in Hurricane
J2, J5 populated

One other thing to note. Starting with the FT schematic, this board has R10 at 220k and R12 at 22k. Previous schematics and all the parts listings have R10 at 22k and R12 at 100k. Looking at the photo of your board and seeing other instances of this board, I believe the FT, CFTBL and IJ schematics are wrong.

Edit: forgot to mention that in the Red parts manual it incorrectly lists the bypass capacitor for U1 as 100uf whereas in the Green manual it lists it correctly as .01uf.

So, to answer your question, you can use any version of this board in IJ as long as you have the correct plugs populated (J2, J3, J4). Or, you can simply buy the GLM board which has all plugs populated and some nice extra features like status LEDs:

Also, I fourth the suggestion of repinning your connectors. New board alone may not solve your problem.
