Wondering if the seminar presentation will be recorded for the people unable to attend in person. pinballnews records audio and video. 2023 https://www.pinballnews.com/site/2023/10/27/pinball-expo-2023/ all the previous years https://www.pinballnews.com/site/?s=pinball+expo @cait001 : enjoy that an...

I got asked to present at Pinball Expo 40 and I've finally solidified that and booked my flight and hotel. Spending over $1k to go give a presentation on pinball ancestry is totally on brand for this absurd and delightful hobby! :) I'm getting super hyped to experience Expo for the first time, and ...

Did the speech ever work since you have the game?

If not, start here maybe:

Bonne chance!

I do not have the Arena game manual, however the 1986 Gold Wings manual (another System 80B game)
indicates the following for the MPU switch 6: Bonne chance!

Bravo !
Les connecteurs sont souvent la source des problèmes dans les machines à boules de cette génération.

If you have a bit of time, you really should visit Seven's Pinballorama in Cornwall, just steps from Charlottetown, worth a visit!

Merci pour la clarification. Là c'est clair. Problème intéressant et le fun! Pas de petit point sur les afficheurs veut dire que le haut-voltage (190V provenant du SDB J3-8) n'arrive pas aux afficheurs (comme l'a indiqué Maxime) ou il y en a un qui a un short. As-tu mesuré le haut-voltage sur les de...

Que veux-tu dire par 'plus rien depuis ce moment' ? Le MPU ne boot plus? Son LED ne flash plus 7 fois au power-up? Si c'est le cas, ton +5V ne se rends plus au MPU. Il faudra vérifier le +5V à la sortie du SDB sur TP1. Ensuite, vérifie que le +5V arrive au MPU - TP5 sur le MPU. Il arrive souvent que...

Possiblement une issue avec le connecteur et ses pins J1 sur le MPU. Ou un des fils de ce connecteur ou plug ne se rend plus aux afficheurs. Ou il y a un short sur un des afficheurs qui n'a pas fait sauter le petit fusible sur le SDB. Ce que je fais pour tester le dernier cas ci-haut est: - machine ...

Thank you BritPin, I am glad I was able to help in the limited time I had.
I'll PM / phone your husband later to arrange another appointment for the other needed repairs.
All the Best!

Bravo, nice picks! Hope I'll be able to go next year.
Asteroids is a nice and fun classic.
And a 1974 Bally Bali bingo - seems a nice project

Got the machine working for now at their place tonight however there are a few more connectors that need repinning, especially the usual J3 on the Solenoid Driver board - I would gladly do that later when we can match our busy schedules. Thanks

Thanks tombiosis !

Agreed with mrmikeman. These seem to look like small split posts - each made in two-halves,
where the transparent ball guide plastic should be sandwiched in the middle instead of on top?
Check if similar to those by PBR:

To answer your question, yes - same value, same tolerance, same power dissipation (or use a 10W slightly larger, with same other specs). Check if the replacement resistor is 'flameproof'. I often order from Digikey.ca If they do not have it, Sayal in Toronto or eBay would be good possible alternate ...

Well done Cjs001, Bravo! I think I have all six sounds on the Star Battle now - the Tone A & B potentiometers needed to be adjusted. Need more time to test and confirm. The confirmed tones produced by this Coffee-Mat Star Battle are: 1- Credit (coin switch) 2- Tilt 3- Free Ball (Extra ball award...

Thanks all !

For info: I received a PM last night from a new MAACA member who owns a working Coffee-Mat Cosmic Wars with a few sounds missing too. Similar electronics. He was going to check electrolytic capacitors on his board. Regarding the comment in the original post: “I still need to replace U6 on the main l...

Oh cool, thanks Xylog for this info. On the roof of your Sunfire? Wow, impressive!
...I am aware that the machine went to at least one other MAACA member before being traded to the person I am now repairing it for.
Small World indeed!

While always busy at work and at home with limited spare time available, managed to progress on this interesting and rare circa 1978? or so early solid-state Coffee-Mat Star Battle cocktail pinball machine that someone brought me to repair a few weeks ago. Not much info on the web on this one. DSCF0...

Jeff, Looking at the videos, it appears that: - the G relay stays activated correctly for the full expected time, perfect. - But the BB relay drops after 3 or 4 pulses around when H gets activated. Still most probably score motor contacts. Check score motor 2C contacts first. Could you please post a...

This related post on pinside should hopefully help.

Good luck!

The issue is most probably on the score motor if you already have tightened the relays' contacts stacks and cleaned & adjusted/gapped their contacts (relays BB, G, and H delay relay). Chances are that either score motor 1A contact is dirty or not gapped properly, or if BB & G relays drop bef...

Looking at the schematics, the G and BB relays and their contacts need to close and stay closed for 1/3 score motor rotation, e.g. for the 5 impulses of score motor 1A to make it to the 1000 pts relay coil for a touchdown (I assume another contact adds the other pulse for 6 points total). From my ex...

Wow, impressionnant, Bravo!
