Title: computer to jamma cab question
Post by: muell67 on July 21, 2005, 08:52:24 pm

I have a jamma candy cab and a J-pac. I would like to hook my computer up to the candy cab just temporarily. When I get the cash Im going to build a computer with a arcade vga card for it. My question is how do I hook my computer up without a arcade vga card. Can I just hook it up and my computer will detect the resolution for the arcade monitor? Im guessing know so what do I do?

I'm guessing no.  So what do I do?

As you guessed, It's not that easy.

You should really read this page...

http://easymamecab.mameworld.net/html/hardware.htm

To summarize...

For the official Windows MAME release (or MAME32) on a
15kHz Arcade Monitor or SCART TV -- Ultimarc's ArcadeVGA

For DOS MAME on a
15kHz Arcade Monitor -- Ultimarc's ArcadeVGA.

For AdvanceMAME on an
Arcade Monitor -- Nvidia TNT2, Trident Blade T64, or Matrox G400 --
combined with JPAC (or Video Amplifier)

Note that it's VERY important that you use a J-PAC for the above setup.
When you first boot your computer, the BIOS screen is at too high of a refresh for an arcade monitor and will damage it.  The J-PAC senses this and divides the signal to protect your arcade monitor.
