I don't have paperwork for model 1112 (5 coin multiplier), but it should be close to a 1096 (5 coin multiplier) and 1114 (3 coin multiplier) machines.
1112 vs 1114:
- the x2 and x3 multiplier units and payout unit are the same. The 1112 will have a x4 and x5 unit also.
- the coin unit is mostly the same, but steps up 4 times on the 1112 vs 2 times on the 1114.
- most of the circuits/schematic wrt handle release, reset, lamps, win meter, payout should be the same.

many of the 111x lowboy slots were dollar machines, so the 5000 manual in /bally_manuals/ on the above site will have exploded parts diagrams for things that may not be in the 2400 manual.
