Can a capacitor be added to the keywiz?

(1/3) > >>

Hello from Maine,

I have happily used the KeyWiz in default mode for a few cabs, and used keyboard hacks for 1 player cabs.

Well I just programmed a KeyWiz for a Gauntlet cab, that is very different than the keywiz default layout. I assumed that the keywiz would permanently become what I programmed it as, but it resets to default whenever power is removed.

I thought mine was broken but some browsing of the forum shows that people have their uploader running at each startup.

*Bummer*

Apparently it forgets at power loss, is it possible to solder a capacitor to the keywiz so it will remember the custom keys all the time?

Thank you,
Craig

Is it a WIndows based system driving it?  If so, just use the Virtual EEPROM feature.

Email me if you need help setting it up.

Thanks for the reply Randy, and thanks for undercutting the competition with your awesome "keywiz eco 2"

But I was surprised that it didn't remember the custom set once powered off.

I would assume (but I'm not an electronics guy) that if the keywiz remembers the custom set when it has power from the ps2 lugs that a capacitor soldered to a pair of points on the board could keep it powered so the custom set wouldn't have to be re-uploaded every time.

Am I correct?

To answer your question I am using DOS, I added "kwdos c:\a.kwz" to the end of my autoexec.bat, I am still setting up the cab and computer now but I assume it will work.

Cheers,
Craig

It was a design decision.  EEPROM adds cost, complexity and would make two of the already limited number of inputs unusable.  It's one of those things that very few people really need, so it was omitted to benefit the possible needs of the majority.  A fast uploader app is on the way and includes "stealth" features, so the EEPROM won't be missed at all by Windows users.

I would say no. Or at least it wouldn't work for very long.

Most would just change the key assignments in the application, making all of this "moot".  What are you running that doesn't allow this?

MAME 61

I realise that I could have configured the app and just wired everything up as whatever, but it seemed more organised to program the keywiz to use the default MAME keys.

Anyway, no bigD, I have the uploader all set up, all is well.

Cheers,
Craig
