Title: Wanted: cheap keyboard encoder or hacked keyboard, Din 5
Post by: IceCold on June 05, 2004, 07:29:30 pm
Okay, basically I do not want to go through the trouble of mapping out the matrix of a keyboard.  I am looking for just a basic encoder(will need at least enough for 2 joysticks, 3 buttons each, start and coin buttons).  Or if you have a hacked keyboard laying around, that would work too.  I would really preffer if it's Din 5(not ps/2, looks kind of like it but is bigger), but if the price is right I'll just get an adapter.  I do not want to buy an Ipac, and not be using many of the inputs.

I have stuff to trade(video game systems, computer monitors, computer hardware, small amount of arcade stuff, etc.) or can pay cash.

I'll do one for you, BUT, I will charge you as much as an encoder costs, as it takes a LONG time to hack them.

Yeah, I figured that would be true  :-\

I'm hoping somebody has an old ke18 or something they're not using.

I would just buy the cheapest encoder out there and be done with it. I have used real encoders on projects with far less inputs than that. You need 18. I have a real I-Pac in a machine that uses 14.

I wouldn't recommend using a keyboard hack for a 2 player panel. It's too difficult avoiding ghosting/blocking.

It's ok hacking a keyboard yourself for the challenge. But as Paige says paying someone else to hack a keyboard and then ship it to you is going to cost as much as an encoder.

If you want to avoid the hassle of mapping out the whole matrix then I have a tip. Pick one of the rows or columns (doesn't matter which one) and use it as a common ground for all the buttons. This will give you an absolute guarantee of no ghosting/blocking. The main downside of this approach is that you won't be able to be fussy over what keys you use. It's also unlikely you'll get the 18 inputs you need.

If I have an old keyboard in that style at work (I think I do) I would hack it for you for $24 plus shipping.  This would include a set of Euro style terminal blocks for easy wiring.  I really don't think it is worth it over paying a few more bucks for a real encoder.  SO...I would do it but I recommend against it.

the minipac from ultimarc is only $29

The Keywiz eco is $26.95 (+6.50 shipping)  That's about as good as it gets.

That or the minipac would probably cost you close to what someone's going to charge to to hack a KB and you get better performance out of these two devices. They'd be easier to maintain, too.

I guess I'll either try to hack a keyboard(I have hacked multiple gamepads, how much harder can a keyboard be  ;) ) or just buy an encoder, and a converter to turn it into din 5.

I'll probably hack a keyboard, becuase I'm trying to do this project for as cheap as I can(already had the 14" monitor, already had the 100mhz machine, already have extra keyboards, already had the joysticks I'm using, already had a hard drive big enough for vantage and the roms, etc.)

It's not even that I don't have the money, it's just the accomplishment knowing that you turned a bunch of stuff you weren't using into a sweet classic arcade machine.

Ah, gotcha.....

Its really not that bad. I've done a couple and they weren't that hard, just time-consuming. There is a program out there that will show you what scan code and key is being pressed. I can't remember what its called right at the moment, but I found it very useful. I'll see if I can find it and I'll post a link.

100 mhz? What kind of 2 player simulatneous games will run on that? Why don't you just do a single player panel?

I was thinking Gunsmoke was 2 player simultaneous, but a quick check of KLOV shows it's not.  I'll have to check if there is a need for a 2 player cabinet.  Thank you for pointing that out.

Maybe this will end up being simpler(and cheaper, less joysticks and buttons) than I thought.

Are you going to use VAntAGE?

Heck yeah!  I've got it configured and it runs all the games in it plenty fast.

I've been trying to see what I can do to help the Vantage project, i've been following it closely.  I think I might offer a reward to the first person that gets something big working(maybe like spinner support or something) I haven't decided yet though.  Just to provide some incentive.

Spinner support is coming.  How about a reward for a game that is NOT a Z80?  Like Centipede?

Good idea, I'll see what kind of reward I can offer  :)
