Im trying to make a jamma test unit in my garage.

but i wanted to take an old pc monitor to test.my boards

but i skimmed the plug now i got

yellow , blue , grey  , red , white , orange , brown , black , green

& my jamma controller ? harness is wired to received a Arcade monitor

so im confused... how could i hook this up i seen it done on some site but it doesn't show

how....

thanks

Skimmed the plug?

Does your monitor go down to 15kHz?

Is your PC monitor an old VGA, or SVGA type?
If so .. it's not going to likely work, even if you had the pinout correct.
The Horiz scan rate of these type monitors won't go as low as an arcade board,
or an arcade monitor (15KHz).

Now, if it's a really (really!) old computer RGB monitor, it will work fine, I'm talking like a monitor from a very old commodore color. Maybe even a monitor from an old apple IIe.

good luck anyways!

Yup like the others said, an old pc monitor won't work at all. Should have asked before trying as now you have a hacked cable.

There are some certain pc monitors that can be used to do this, but not just any monitor. I had a list of some monitors that you could hack into doing it, but don't have the list anymore.

For instance. Here is a pic of someone using an old mac monitor that can do it: http://www.ionpool.net/arcade/test_bench/arcade_test_setup31.jpg

Best thing is to get a regular arcade monitor. Much easier to work with and no hacking needed. Anyways, a pc monitor will give you worse resolution (in most cases) than a real arcade monitor.

ahhh geez didn't think about it....
thanks guys .

but it's rather old but not THAT old..... gnahhh...

ill remove one soon from a cab i just bought

im  just scared it would have charge in it ...
as i normally don't play with monitor for that reason.

Unless you stick you finger under the suction cup on the tube, don't worry about it at all. If the monitor is off, you cannot get shocked by touching the pcb board, frame or tube (unless something is possibly broken or been badly hacked).

Just keep the fingers away from the suction cup and you will be fine

If you are just moving the monitor around you do not have to worry about any residual charge.  If you want to remove the anode and stick your tongue in the hole... that's a different story

Seriously, unless you are going to be installing a cap kit or trying other repairs, don't worry about it.  Just keep your hands away from the anode (which is covered by a rubber suction cup) and you'll be fine.

great thanks for the info ^^
ill do it tomorow...
I think the monitor itself is a 13'' which is cool if it still works.... since it's so little...
fits everywhere...


also i have an other question ...

theres a missing White connector on the monitor..

cause if i look closely on my jamma test setup theres 3 white connectors 2x white one that goes on the board but there an other one i think it's for the power?

but on this tiny monitor it was 2 wires going to a fuse holder....
does it matter ? or i need to buy a plug .?

You will have to take some pictures as I don't understand what you are trying to describe.

see the brown & Beige wire with a connector....

on my last monitor where i had this jamma setup  it had it.it clipped together.

but on this one theres none the brown & white wire were directed to a fuse holder instead....

I assume you are talking about the connector I circled.

That is the connector for power. It is suppose to connect to a pass-through transformer (115V to 115V) then into power that enters the cab (115V).

If you say that someone put a fuse on this connector on the other monitor, it was probably because just for extra protection before it went through a pass-through transformer (for protecting the monitor from power spikes). Leaving the fuse there and then connecting it to the transformer won't hurt it, and is a good idea (but the fuse is not really needed).

Unless it's a really recent monitor you MUST use the transformer!!!!  Don't connect the power directly to 120V!!!
