Adaptors

Jamma Adaptor

These are links to pics of various types of adaptors and any that are for sale will have a price next to them. I've never liked the prefab adaptors that have been around for years. Most of them constrict the traces on one or more lines & do not allow you to ease the current draw as needed, so I've always made my own hardwire versions whereby I could control the adaptor rather than adjusting the power supply everytime that a board was changed and I like having a completely repairable adaptor should something ever go wrong with it. Being able to control I/O lines easily is another plus to them,e.g., the pads that need to be toggled low for cocktail cab use, or in simply rerouting power lines to points that really need them, such as with the Galaga where not only is the edge connector fed with 5 volts, but the video bd & CPU boost connector are fed, also.

The most important thing to remember when making your own adaptors is to start with a plain fingerboard that utilizes wide traces. You don't want to start off with idiotproofed fingerboards that are labeled on-board when etched because they put restrictions on all current paths. If you want the positions numbered or a pinout right on the fingerbd to idiotproof it, do it with white adhesive tape, or just plain scotch tape, and a fine point Sharpie & after it is finished & tested you can remove it. You need to avoid same side boards... ones where all your wires will go on the top side... for the same reason of trace restriction and this type also usually has circular pads to solder the wires to, another thing to avoid. Back in the 80's these were used in gray area gaming machines & the trouble with them was that the circular pads give you a place to start peeling the trace off the board in addition to being a current limiter. Same side with pads all on one side made the harness act as a handle to just rip up & away from the board... which happened frequently on the dark locations that these machines were set on.

All our adaptors are from classic board to the newer, better JAMMA wiring standard. We do not make, sell or recommend any JAMMA board to older, well-used classic wiring harness adaptors. Jamma to classic cab with DC power, such as a Jamma to Galaga adaptor, are alright for simply testing a Jamma bd in the cab once in a while, but for permanent use of a Jamma bd it is best to wire Jamma complete on a vacant wall thus preserving the classic intact, while being able to play any of the Jamma game bds.

Our harness maker has been inundated for the last three months with all the custom pieces... harnesses, adaptors, ribbon cables & such & we have been forced to bump pieces to the front of the line when payment has been received... out of normal order of first come first serve. We have been continuing the struggle trying to get back on track without much success. Another hindrance is people ordering specific harnesses, or adaptors, & then backing out when they find their pcb is fried, cab unsalvageable or just not worth their effort to continue with the restoration. All the time spent on these pieces just detracts from available time in making the things you do want. As a result of this, at least temporarily, all custom pieces will be made upon receipt of payment only.
