 I've got switch matrix problems and some diodes need to be changed. The 1N270 diodes which were used by Gottlieb are obsolete for a long time. May I use any type of diode like 1N4148 1N4004 1N4007 ?

 the pinball lights on, the power-on sequence is OK, the playfield is in attract-mode, the displays are OK, but I can't start any game. Pressing the CREDIT button doesn't do anything.

 ALL my displays are off. what should I do?

 one of my displays shows very bright digits

 some of my displays are not working properly: missing segments or digits

 my board (PI-80 or PI-1/X4) is working properly but the fuse which protects the +60V power supply of the displays burns regularly, even if the displays seem to work properly. I change it, it works for a while, then it burns again.

 the pinball lights on, the power-on sequence displays an error message, it is impossible to start a play : when I press the CREDIT button, the TILT relay clicks twice, the displays show « TEST » and the play does not start

 once you turn the game on, the game goes crazy, like turning lamps randomly on the playfield, firing coils or even shooting balls in play. what’s going on?

 the game in progress ends abruptly and a "STUCK SWITCH xx" message is displayed. what's wrong?


 Can I collect VAT? (for French or European buyers)

 I made a mistake when I placed my order or I changed my mind since. May I return the board and get a refund, or swap it for another board?

 Do boards come up with a guarantee? I purchased a board and installed it in a 3rd party game, does the guarantee apply?

 As I am not in a hurry at all, may I save on shipping costs and wait till the next pinball expo to purchase boards at your stand?

 Before ordering I need to know about the legalities of using the Gottlieb name/intellectual rights

 I sent several support messages but still no answer after several hours. As a customer I was expecting a much faster reply!

3-Technical questions

 Should I get new eproms and/or use the original proms?

 I'm looking for my game manual and/or the original sound proms for the replacement sound/speech board. Do you sell them? If not, where can they be found?

 Is there a development kit available to develop new games or different game rules for certain games?

 Is it possible to update the software by means of an USB key or a simple serial port?

 An idea: replace the prom that contains the software by an SD card. SD cards are cheap, easy to program & swap.

 I would like to keep using the coin slots, is it possible?

 No reliability problems over time?

 Must the game be fully operational before installing the new board?

 To make things short: I receive the new board, I install it, I turn the game on, and it will work no matter what the game's original condition?

 Are Bally/Williams replacement boards being considered as well?

 Are there documents that explain the boards' use, menus/setup, etc..?

 Do boards drive the excellent replacement LED displays from Boston Pinball Company ?

 is there a setting to reset all drop targets of the game in one single shot, rather than in sequence?

 My game is not among the current list of available games for the PI-80, what can I do?

 Will the PI-80 final board run on all games of both System-80/80A series?

 Two playing modes exist on James Bond game (timed and bonus), will the PI-80 board offer both?

 I own a "Grand 8" from Christian Tabard (France), is the PI-80 fitted for it?

 Regarding sounds, are all sounds of non-speech-capable games driven?

 Rather than the sole credit button, can the player enter his name in the high scores tables using the left & right flipper buttons?

 Do I need an additional sound board or it is embedded into the PI-80 board?

 Does the giant pinball display (that works on PI-1 and PI-1/X4 boards) also work on the PI-80 board?

 Can we dream of a speech-capable sound board (or emulating an SC-01 chip..) ?

 What does the small A24 board, located above the original CPU board, do? What should I do of it if I install a PI-80 replacement board in my game?

 I would like to install my PI-80 board in a game (80 or 80A) but I had asked the other games series (80A or 80) upon ordering the board. what can I do? OR new games and features have been added to the PI-80 board. how to have my board updated?

 I would like to add speech to my Haunted House while keeping it in single ball mode, how to do that?

 what are the numbers and positions of each connector which goes to the board? a picture would help!

 can the original GE44/GE47 lamps be replaced by modern LED-based lamps?
