reset a pcb without shutting down the cab

Post by erzane »

I'm wondering about how to reset a pcb without shutting down the cab..
If there is a button I could set by some way like on consoles.

Thanks

I guess you could put a switch on the 5v line on your jamma harness. Unsure why you'd want this though? :)

I'll try, thanks 8-)
Sometimes you want to reset the game because you didn't started it well and you need to shut down the whole cab, it's not so good for the monitor to often shut down and start.

Put a separate switch on the PSU.

Also, you're asking for trouble if you're just switching of 5V. That still leaves 12V and possibly -5V live. If you're shorting either one you will melt the jamma connector in seconds.

I second what nem said. Seems unnecessarily risky to me.

Just die and don't continue. Speed up the credit continue screen by mashing the buttons and start again ;)

Press the test button then quit out of test mode?

Do you have to go through all the warning screens again when you do this? :oops:

Ahh, you're just wanting to reset the game? Apologies, I missed that part :oops:

Seems slightly excessive, but a switch on the 5V will work perfectly fine. There's no risk involved, at least no fear of a short. Just don't try to change boards!

Yes, only resetting the game with a toggle switch
So hooking it on the jamma edge +5v (D, E, 4 or 5) and add a GND and all will be fine?

If you do that you will get the short I warned you about :)

You want a single throw switch, one that closes a circuit at only one position. The other position of the handle is off. Like a power switch. You have to do this for all four 5V pins, so 3, 4, C and D. Just cutting power to one will not suffice, you have to cut all four.

As nem said, you need to switch all 5v pins at once.

I made something similar for my STV multi prior to the auto-reset firmware being released. Before that you had to power cycle the game board and I didn't like powering the monitor off/on unnecessarily.

However, for starting a normal game again I would probably just suicide and start again though as zak suggested.

Sorry I mistaked it, I wanted to say 3, 4, C & D. So, shutting down all +5V, I see now, thanks Nem.

If I refer to Francos setting:
Franco, you wired 2 more positions as the extras both 12v, why? :wtf:

About doing it through the test button, as Crunchy said:
is there any difference between shutting down all +5V instead of doin' it via the test menu?

Zaks suggestion is also good but too slow compared to the others propositions, sorry Zak :D

Its a DPDT switch so I thought it wouldn't hurt to wire up and switch 12v off at the same time.

DPDT? What is 12v doing when ON-OFF in that case?

DPDT = Double Pole, Double Throw.

Basically it's two ON-ON switches connected together. As only one of each side of the switch is wired up it acts a dual ON-OFF switch.

When the switch is in one position both 5v and 12v are connected. When the switch is in the other position both 5v and 12v are disconnected.

I see, thanks, and why hooking also 12v?
p.s. why didn't you hooked any GND?

This. Why would you bother with a switch? It's also potentially shortening the life of the pcb of your doing it a lot.

forgot to ask about the wire:
is a 24 or 22 awg enough for that switch?

Yosai:
why does it makes the life of the pcb shorter?

I’m sorry this is another reply you haven’t asked for but I’ve always considered the inconveniences of no pause and reset buttons as just part of the experience of playing games that are meant for arcades.

I use mame and I still don’t bother with the reset button. Usually quicker to just die.

This may be helpful for games that keep rank between games (for example : Batrider).
