Struggling with my first build... Games Family 2100 PCB/Jamma inside.
(1/1)
Mouse92im:
Hi all,
First time poster/newbie here. Glad I stumbled across a forums site after my many failed search attempts. Hoping someone can ease my frustrations with a suggestion or two...
I'm at the tail end of my first build. Decided to go with one of these Games Family systems. Originally picked up a 3149 in 1, but ended up sending it back thinking it was faulty. Just received a second unit, this time a 2100 in 1 with the same issue.
I can't seem to get any screen or sounds after fully connected and fired up. Feels as though I have quadruple checked all my wiring, but not getting any results. Here's a small list of things I have tried troubleshooting so far...
* Arcade monitor has power
* WellsGardner 60hz monitor and RGB, Gnd, and sync are connected
* Jamma harness +12v, +5v, -5v, Gnd are hooked up and working. Tested with voltmeter.
* Jamma harness seems to be wired correctly. Plugged it into my original Golden Tee pcb to test and works fine.
* Using 20 pin ATX per manual to power the PC
* PC fan and hard drive spinning
* tested a second ATX power with same results - no signal to screen
* attempted to hook up CPU monitor to VGA port - no response/no signal
I'm stumped.
Anyone have an idea where I'm going wrong?
Thanks in advance.

UPDATE:
Obviously it helps if I plug in the CPU processor. ;D
Got it up and running.. All is good, with the exception of the monitor.
I am unable to use the arcade monitor in the cabinet because I don't have a way of connecting it.
Back to the web to find out how...

those multi-in-1 boards often have a dip switch you have to adjust for it to output either VGA (in the case of a computer monitor or tri sync arcade monitor), or "15k" for output to a standard res arcade monitor through the jamma harness connections...
all the arcade monitor needs for video is Red, Green, Blue, Ground, and Sync to operate. your multi-in-1 board should have come with a book with a diagram of the JAMMA harness and it's connections. if for some reason it didn't, here's one:
wire straight from the harness to the monitor. no conversion or other hardware outside of a physical plug should be necessary to operate..

Thank you. This particular 2100-1 didn't come with that little VGA to 6pin plug that connects to,the second deck jamma Board. I've contacted Andy at Ultimarc and also got a hold of a guy who sells parts for it straight out of china.
I opted to just purchase a new VGA monitor and planning to replace the CGA arcade monitor. Picked up one today. The plug would have cost me $6 plus $32 shipping. Just didn't want to wait any longer for something I'm not 100% sure would work. Kind of tired of fiddling with it all and rather play it.
Now I'll have a good arcade monitor that I'll need to get rid of.

i see. this is wone of those computer with a jamma I/O board on there.
most of the multi-in-1's i've seen are an all in one board. (6/32/60 in 1) but yeah, it should have come with a cable to pass the video from the motherboard to the I/O board to go out the jamma. i guess they assumed you'd just be hooking this straight up to a VGA monitor.
