I've been repairing pins since my first acquisition in 1991 (Gottlieb Centigrade 37). My collection of 60 or so games is split between Gottlieb EMs and a mix of solid state games.

Oldest game: 1962 Gottlieb Rack-A-Ball
Newest game: 1995 Williams Attack from Mars

Order placed for Jersey Jack Pinball Wizard of Oz, scheduled for March 2012 delivery (finally delivered September 2014)

Chris, blanking signal is actually a periodic signal I know you're in the process of editing, but it is an important distinction. Obviously it's high most of the time, but it dips low at least once every display interrupt (to clear the displays).

If only it worked as desired to prevent coil lockout (*sigh*)

Playground:

Using a SIMTEK STK12C68-SF45 in various manufacturer's boards Board modifications:

Sega or Stern -- the HSB pin number 26 needs to be removed.
Data East -- remove HSB pin number 26, and make a link between +5V and B+.
Williams -- some games use larger RAM circuits. To be able to use this NVRAM, add resistor 1.5k on R93, and remove O ohms resistor on W3.
