Newbie Question - Icade 60-1 to Arcade SD

[SSGWJL]

Please be patient with me, I am new.

I just bought a built cabinet with an icade 60-1 in it. I also purchased an arcadeSD card with the intent to replace the iCade. I examined the Jamma pinout comparison before purchase, and it looked like the only thing I needed to adjust was the +/- speaker connection (reversed). However, I've come across a couple of other problems I was hoping to get some advice on.

1. The power supply in this cabinet is a dell computer power supply... it uses the molex connector to plug into the Jamma board (not using the Jamma power). With the arcadeSD, I need to use the Jamma harness for power. My question is, can I simply splice the +5V and ground (from Jamma harness) into the existing molex connector (which is connected to Dell Power supply) ? Also, the ArcadeSD states the 12V isn't needed (optional), but will it hurt the board if I splice it in also (or will it cause issues if I don't use it)? Outside of that, I guess I could get an Arcade power supply.

2. This is the bigger issue I think. My control panel has a 1P joystick (Magstik Plus), three 1P buttons, a trackball and 1P & 2P start buttons. The trackball is connected to the icade using the trackball on-board connector (not Jamma harness). I could wire the trackball to the Jamma harness using P2 (pins 18-21 on solder side) but the blade connectors (if that's what they are called) and wiring aren't there on the Jamma edge connector. Can these be added... if not what are my options?

Again, apologies for being dense, but I am new to this hobby and looking to get this cabinet finished for my kids before Christmas. If pictures are needed I can supply those.

Thanks in advance.

Yes you can just splice the +5 and ground from existing ps into harness. At one point in my cab I needed a good switcher, I robbed the happ supply from my arcadeSD cab and wired in a 1amp 5v tablet wall wart. Hope that will get you running at least.


I'm no help on the trackball, I'm sure PL1 will chime in with links to the stuff you need to do. 

Enjoy the upgrade, granted it's no longer getting any updates, but it's still a fantastic plug and play (well... not just yet for you ) board as it stands now. I still use and enjoy 2 of them in the housecade, the pi stuff can be too much at times.


good day.

I could wire the trackball to the Jamma harness using P2 (pins 18-21 on solder side) but the blade connectors (if that's what they are called) and wiring aren't there on the Jamma edge connector. Can these be added... if not what are my options?

Page 7 of the manual covers trackball requirements.

1. What type of trackball do you have?

Note: Requires modern digital trackball units utilizing a 74HC14 I.C. chip. (Older, original Ataritrackball units are not supported).  Even though modern trackballs may be labeled “AtariCompatible” they are NOT the same.Any modern trackballs sold by Suzo/Happ will work, e.g.
http://na.suzohapp.com/trackballs/565500xx.htm
http://na.suzohapp.com/trackballs/560100xx.htm

2. There are 6 connections for the trackball.
- As you mentioned, pins 18-21 are the four data lines.
- You'll also need 5v and ground to power the trackball optical circuits.
- Verify the trackball connector pinout order in your 60-in-1 manual to ensure you make the correct connections to the arcadeSD.
-- Make a list of which wire color is associated with which function.
-- The pinout is probably similar to CON3 and CON4 in this example.


3.  Your choice on how you want to make the connections.
- Your JAMMA harness probably has female Quick Disconnect (QD) connectors on the wires leading to pins 18-21.


- Your trackball probably has a connector like this.


- You can cut the connector off one side and crimp on a connector that mates with the other side (medium-hard, slightly destructive way) OR make an adapter cable that mates with both ends without cutting off the connectors (harder but non-destructive way) OR cut the connectors off both sides and use a euro-style terminal strip to make the connections. (easy hack way)

First of all... thanks for the replies... I really appreciate it. I understand the required XY Jamma connections for the trackball per the ArcadeSD manual (which is a newer happ version), I guess my question is regarding my Jamma harness itself. There are no wires for 18-21 on the solder side and there are no male connectors that could accept female quick connects. Can the male connectors be added to the edge connector or do i need an entirely new Jamma edge connector (hopefully not). Regarding the 5V and ground from trackball... would I just splice those into the 5V and ground going to the power supply? Also, and this is probably a dumb question... but is there any harm in running two power supplies? I'm tempted to get an arcade power supply to run the ArcadeSD PCB (5V+ and ground only) and trackball and leave the rest of the power (marquee lights and LED strip/LED coin lights) on the existing DELL computer Power Supply. The intent would be to migrate the lighting to the Arcade power supply once I have a better understanding... everything works now... so I don't want to create new problems. Both power supplies would be plugged into a surge protector/power strip which would be wired to the external switch on the back of the cabinet. Thanks again for your replies.

a newer happ version

Here's the pinout for Happ red boards.   

I guess my question is regarding my Jamma harness itself. There are no wires for 18-21 on the solder side and there are no male connectors that could accept female quick connects. Can the male connectors be added to the edge connector or do i need an entirely new Jamma edge connector (hopefully not).

The data lines from the trackball harness are probably too short to reach the Jamma connector.

Solder extension wires to the eyelets on the wire side of the connector, just like the green wire on pin 16 (Coin 2) or the red wire on pin 14 (Service) in this picture.



If you can't see the eyelets, there might be a protective cover or strain relief wire clamp covering them.

BTW posting some pics of the connectors will help us help you.   

Regarding the 5V and ground from trackball... would I just splice those into the 5V and ground going to the power supply?

Yes, you can get 5v and ground for the trackball from the power supply.

The trackball's optical circuits will draw less than 100 mA total.

is there any harm in running two power supplies?

No harm doing it the way you described.

Thanks again... I got everything setup. Ended up buying an arcade power supply (using +5v for ArcadeSD and +12V to power all the lighting). Now my only issue is with the trackball (see attached pictures) ... the pins on the JAMMA harness for P2 (18-21) are missing. Can I add the pins (not sure what they are called exactly or where I would find them for sale).

Thanks again.

Missing JAMMA edge connector contacts??!!??   
- Some genius probably figured he'd get rich by leaving out $0.02 - $0.03 worth of "unused" pins.   

Replacing the missing contacts is far more trouble and expense than it is worth.

You might as well get a replacement harness.


Scott

[SSGWJL]

LOL... I figured that was probably the case. Oh well... can you recommend a quality JAMMA harness (preferably one with connectors already included for all wiring)? Thanks again for the help... appreciate it.

No particular vendor recommendations off the top of my head.  Does anyone else have one?

AFAIK no JAMMA harnesses come with plug-and-play Molex(?) or Dupont(?) connectors for your trackball so you will have to mod that part of the harness or make an adapter as mentioned earlier.

This is a pretty common 60-in-1 builder technique.  Pull any pins not being used and less wires to deal with.  And if you build enough cabinets you can start making your own harnesses with the leftovers.

Any cheap JAMMA harness will work fine.  You may find it easier to buy a $10 harness, pull out the wires you need by popping the pins out and then transplanting them m into your existing connector.  Then adapt that to the trackball.

If you want to make a clean installation, take the trackball apart and remove the existing harness.  Make a new one that connects to the optic boards on the trackball with Molex .156 kk series housing and pins using the wires you harvested from the new JAMMA harness.  Transplant this harness to your existing JAMMA connector in the appropriate place.
