Makvision 27" Tri-Mode CRT
buttersoft:
Should not be an issue for MAME, as long as everything is set up right so the computer never tries to go over that.
Grant, is that a hard limit on the dot clock or something? Or are are you talking hard 31kHz, and as long as you stay under that you can play with lines/FPS as usual?

no idea, i just fix them- all i know is if you give this chassis anything over 800x600 (it won't run 800 x 600 but i think it survives)it will run the HOT to hard and short
buttersoft:
Just to clear things up... You're saying 800x600@60fps won't work. But would 800x600@50fps? The latter would be just over 32kHz, i think.

never tried, i fix for arcades mainly so the chassis go back to original machine
Vectorfire:
familiarize yourself with GroovyMAME, get a compatible ATI video card and a dedicated PC to run it.
You will also need a video amplifier to up the voltage to Arcade levels, Ultimarc has what you need.
I just went through the whole process with my own Makvision 27" Tri-Mode CRT a few months back, bought a second even for vertical titles.
You need to setup CRT EMUdriver with a compatible ATI card and install Atom15 BIOS drivers on the card to lock it at a safe res and refresh. Even just the boot screen of your typical PC can fry that monitor without this stopgap in place. Take your time!
Will help when your ready/
