Wipe Out pcb and Leader pcb do not have any slide switch on them such as what can be seen on various pong pcbs. The Midway Leader parts catalog does mention the operator adjustable slide switch. The slide switch is within the interior of Midway cabs (upright or lo-boy model) on what is described as equipment panel or mechanism panel.
The Midway Leader wiring schematic calls it: Score Selector Slide Switch while the Leader parts catalog lists it as: Game Over Score Selector Switch
I prefer the wiring diagram description since it describes operator adjustment as a slide switch.
As for the prom file names, skip this old info
-- .a4 unknown MMI 398 10835 75351 was on the chip read as 82s123
.g7 IM5610 read as 82s123 --
Since there are no labels on the two proms on the Ramtek Wipe Out pcb and the logic schematics for both Midway Leader and Ramtek's schematic version that says Leader do not show any name or number for each prom, use these instead I5610C.4d, and I5610C.7g
I would use the ic part number (Intersil 5610) as for the rom name file as such
- I5610C.4d I5610C.7g -
In the DICE source code, the prom function description should also be added to the right of each prom so that way other board owners would know what the function is for each prom.
-- I5610C.4d // character generator I5610C.7g // basic control of ball movement --
btw: A brief description of gameplay as shown in Ramtek Wipe Out flyer.
