MultiBingo hardware working; Nicholas tackles relay/ball-lift complexity; discovers 1952 Bally Miss California.
Nicholas Baldridge has completed wiring on MultiBingo and is playing full games with 13 games now complete but not all tested.
high confidence · Nicholas Baldridge, opening statement: 'I finished all the wiring for the multi bingo and turned it on...I am now playing full games on the MultiBingo...I have all 13 of the games complete in the system'
P-ROC boards have an 8-bit maximum pulse width of 255 milliseconds, which is insufficient for relay timing in multi-second durations.
high confidence · Nicholas Baldridge technical explanation: 'the maximum pulse length is 255 milliseconds, so it's an 8-bit pulse...255 milliseconds is about a quarter of a second'
The Silver Sails trough (from a Magic game) has 8 balls and fits the template for most bingo machines which have 5-8 balls.
high confidence · Nicholas Baldridge: 'The trough that I'm using comes from a Silver Sails, and Silver Sails is a Magic game, and it has eight balls, so, you know, that fits the template perfectly for pretty much every bingo'
Ball count timing is critical in EM bingos because ball 4 is when the game starts looking for replays and winners, and early ball count increments would affect this.
high confidence · Nicholas Baldridge: 'When ball four is shot, that's when the game is supposed to start looking for replays, looking for winners...it would throw the whole timing off'
Early EM bingos used a ball count unit that stepped down when a ball returned, while later games (circa Palm Springs/Palm Beach) switched to trough switches for reliability and cost savings.
high confidence · Nicholas Baldridge: 'in the earliest bingos, there was a ball count unit...later on around Palm Beach or Palm Springs...Bally implemented trough switches...much more reliable way to do ball count and ball lifting...It was also cheaper'
Miss California (1952, Bally) is an Atlantic City retheme with the extra ball feature removed, likely due to regional gambling restrictions in California.
high confidence · Nicholas Baldridge: 'Miss California is exactly the same game as Atlantic City, except it was themed for the West Coast...apparently in certain jurisdictions or maybe California in general gambling for an extra ball was illegal at the time'
“There something about that thrill of creation, which is something that you don't get just from restoring a game, But if you have the ability, the facility, to make your own, I highly, highly recommend it.”
Nicholas Baldridge @ ~47:30 — Reflects on the emotional/creative satisfaction of building MultiBingo from scratch vs. restoration work.
“now the bingos I just have to hand it to Don Hooker every single way that I possibly can they were so clever he was able to determine in hardware EM only how many balls were lifted and if the player was trying to cheat...it's very impressive.”
Nicholas Baldridge @ ~25:00 — High praise for EM bingo designer Don Hooker's engineering ingenuity in ball-lift mechanics and cheat detection.
“I can't trust it, basically. So instead, what I do is I cut off the lifter motor as soon as the ball hits the shooter lane. Now, this is dangerous.”
Nicholas Baldridge @ ~30:00 — Reveals a deliberate but risky workaround for mechanical relay timing uncertainties in the lifter system.
“if you're playing it at home the extra ball feature, especially if you have your game on free play it's a little too easy to just keep pushing that button so this gives you a real challenge”
Nicholas Baldridge @ ~55:00 — Commentary on the design impact of removing the extra ball feature—increases home play difficulty and engagement.
“there are many exciting twists and turns that I can take long diversions if I want to and it's all within the bounds of possibility so it's very exciting and I'm just having a blast”
Nicholas Baldridge @ ~42:00 — Expresses enthusiasm about the creative possibilities of the MultiBingo platform for future game implementations.
restoration_signal: Nicholas has successfully integrated modern digital control (P-ROC) with classic EM bingo mechanics, solving complex relay timing and ball-lift sequencing challenges to create a multi-game swappable platform.
high · Completed wiring, functional gameplay of 13 games, custom ball-counting and lifter-override logic using P-ROC boards and switchboards.
design_philosophy: Nicholas's approach to MultiBingo mirrors Don Hooker's EM bingo design philosophy: minimal switches, clever logic, and failsafe cheat detection—demonstrating respect for historical engineering and constraints-based creativity.
high · Nicholas's praise for Hooker's work, adoption of lifter-override logic, careful ball-count timing to match EM behavior, and focus on switch conservation.
technology_signal: Nicholas sought help from custom pinball forums and development channels when encountering P-ROC pulse-width limitations, receiving multiple solutions and community engagement.
high · Asked question on custom pinball forums, received suggestions for coil enable/disable, drive patterns, and community discussion.
product_concern: P-ROC boards have an 8-bit pulse width maximum (255ms) insufficient for multi-second relay operations; Nicholas worked around this with custom enable/disable patterns and drive logic.
high · Detailed technical explanation of pulse-width constraints and workarounds used to drive relay circuits.
restoration_signal: Nicholas sourced a Silver Sails (Magic Screen) trough for its 8-ball capacity, demonstrating cross-game parts compatibility and adaptive engineering to support multi-game playfield swaps.

Atlantic City is a three-card bingo with corner scoring, independently doubleable cards, and up to six randomly spotted numbers per coin.
high confidence · Nicholas Baldridge: 'Atlantic City is actually a fantastic player...It's a three-card bingo with corner scoring...on your first three coins, the center number of each card could be spotted randomly...up to six in total'
Nicholas is working on implementing Bally's Stock Market, a 1970s six-card game with player-controlled collect scheme and double-or-nothing mechanics.
high confidence · Nicholas Baldridge: 'this new game is Bally's Stock Market...the first game that I'll have implemented that uses a player-controlled collect scheme...the first six card I'll have implemented with player-controlled double or nothing'
high · Trough selection rationale: 8 balls fits most bingo specs (5-8 ball range); acknowledged limitation of only 5 active switches at once.
design_innovation: Nicholas implemented creative ball-count timing that increments on ball gate exit (not on lift) to preserve EM timing for winner-search logic starting at ball 4, with failsafe manual override matching EM behavior.
high · Detailed explanation of ball-count increment timing, trough switch 5 state tracking, and how early increment would disrupt winner-search timing.
product_concern: MultiBingo has a race condition in scoring when multiple winners occur simultaneously on different cards; occasionally results in too much/too little score or missed wins.
high · Nicholas: 'if you have more than one winner at a time...occasionally it gets very confused and it will give you either too much or too little score.'
historical_signal: Early EM bingos used ball-count units that stepped down on ball return; circa Palm Beach/Palm Springs era, Bally switched to trough switches for reliability and cost savings.
high · Nicholas's historical analysis of ball-count mechanism evolution and acknowledgment of trough-switch adoption as cost/reliability improvement.
licensing_signal: Bally's 1952 Miss California removes the extra ball feature present in Atlantic City, likely due to California regional gambling restrictions on extra ball wagering.
medium · Nicholas: 'apparently in certain jurisdictions or maybe California in general gambling for an extra ball was illegal at the time...the machine is identical to Atlantic City' except for removed extra ball.
restoration_signal: Nicholas discovered Bally's 1952 Miss California earlier that week—an underdocumented or previously unknown bingo variant that he plans to add to MultiBingo.
high · Nicholas: 'that's a game that I didn't know existed until earlier this week...it's a rethemed Atlantic City.'
gameplay_signal: Removal of extra ball feature (as in Miss California) increases challenge and engagement in home play, forcing players to earn wins more deliberately than pay-to-play machines.
high · Nicholas: 'if you're playing it at home the extra ball feature...it's a little too easy...so this gives you a real challenge.'
product_strategy: Nicholas's MultiBingo roadmap includes Stock Market, Ticker Tape, High Flyer, Dixieland, and rare one-of-a-kind games, enabling preservation and playability of otherwise inaccessible titles.
high · Nicholas: 'there are only one copy known to exist...there will be no other way that the vast majority of people will be able to even think about playing one of those.'
