TOKN KB16 (Tiger-Heli's Testing Complete)
JoyMonkey:
Wow! So basically, the only safe place to use one of these is in a cocktail or alternating upright with a 4-way stick and one fire button. How many emu-cabs have you seen like that?
I think even my poorly hacked keyboards had less ghosting than this thing.

JoyMonkey - I think you can get a working SF layout out of this (with ghosting of the coin keys), but then again, you should be able to get 6 buttons and a joystick out of an 8x2 matrix. You should be able to do this without re-programming the unit and using inputs labelled Coin 1 and 1P Start re-programmed to Z and X as action keys, but you can't. Even with the advertised 16 discrete inputs, I posted previously that the unit would not perform as well as a good keyboard hack (which can get 12 action keys plus two joysticks, plus unlimited admin keys that will cause ghosting), but the KB16 gives you a LOT less than the advertised 16 non-ghosting inputs.
Edit: Later confirmed that you can get a SF layout to work, but you have to re-map inputs and will still have ghosting with the admin keys.

Thanks Tiger-Heli for taking the time to do a proper and thorough review of the TOKN kb16.
It is as I suspected. Of course we have to remember that it still has uses outside of arcade controls. It is just a terrible choice for the button mashing crowd ;)
It is ironic though. Because of mattp's evasion and double talk, the fire stayed lit, and now there is no doubt about his product. A few simple truthful answers might have kept his encoder in play.
Chris:
Incredible.
I can get 14 or 16 (can't remember which right now) unghosted inputs out of the keyboard that drives my cabinet. I can't understand why anyone would design a chip this way.

It's kindof sad to make this my first post, but...
I am the 'proud' owner of a Tokn KB32 encoder and your test results concern me. I havn't had the time to get the KB32 installed in my CP, so I haven't been able to test it yet.
As I read the review, I couldn't tell if you were running jumpers to each of the common connections on the PCB. I may be fishing here, but could that have contributed to the ghosting in some way? I don't have any technical rationale for that question, I'm just curious.
I read everything available on the product before I bid on it (which was scarce) and decided that I would only buy it if I could get it considerably cheaper than other alternatives. Since I paid less than $25 for the 32 input version, I thought I had made a decent purchase. I hope it works out, but at least I'm not out significant bucks for the thing.
I also just checked the Tokn spec sheet on the KB16 and it very cleary says that it does not ghost keys. I hope to test it this weekend, and I will report my results. If it turns out that when correctly attached and used as intended that ghosting occurs, I will be a very unsatisfied customer. I will withhold final judgment until I have a chance to test it. I hope that the simple connection of all of the grounds makes a difference, but I'm not holding my breath.
Mattp, your comments would be very welcome here.
