Hi everyone.
I've had a jamma cab floating for a few years, decided this summer to convert it to mame. After interfacing to the P.C card everything was running fine until the Flyback started arcing to the chassis.
Supposing I replace the flyback, is there a way to get dos to display in 15KHZ? I am using AdvanceMame. If there isn't I may stick a cheap P.C monitor in but I really want to keep the old 15KHZ due to the authentic crap resolution.
I need to run Dos as the computer I'm running is only 1 GIGHZ & 768MB Ram, so CPU power is at a pinch really.
Im using a Nividia TNT2 32MB graphics card. Everything was running fine until the Flyback went. Could it be over exposure to DOS that caused it to go? I was under the impression DOS ran under 30KHZ. It would display dos, just with no SYNC.
Many thanks.

If your Video Card is Supported by Advamame, then yes you can run PURE DOS.
Other things you might consider, sound for DOS (make sure you have it) or get a soundcard that have support for DOS. Advmame supports ac97 no need for drivers with those.

Hi mate
Yea im running pure dos already, its just that it wont display on the 15khz monitor, it has no vertical sync and rolls up and down. I have sorted the sound out.
thanks

There's a TSR called ARCMON that will help with that. It's on my "other" site.

I've had no trouble running older versions of mame (.55 and .78 or .79) on similar hardware with both win98 and xp.
Your vid card may work with soft-15khz (http://wiki.arcadecontrols.com/wiki/Custom_display_modes_(Windows)_-_Soft-15khz)
There are likely reasons you want/need Advmame and DOS that i'm missing though.

thats what I was looking for, very helpful, thank you.
Do you think that booting the P.C and seeing the BIOS startpage (quick ram test etc) could damage the 15KHZ monitor?
Also another problem I was having:
I've placed Advancemenu into the autoexec.bat but it cant recognise the advancemame emulator from start up.
When I run it from the prompt it runs fine i.e
Cd mame
Advmenu

I guess stuff running in the background isn't going to do the world of good for such a low end P.C. Some roms it wont run smoothly. Also I think the emulation from Advancemame and the front end Advancemenu is good, im not too botherd I cant get some modern roms to work.

I was going to say, the bios screens are 31khz progressive, regardless of dos operation, and yes those need to be filtered out or something.

So your saying basically wait a few seconds before turning my monitor on?

Cd mame
Advmenu
it might be a bit long winded but don't you have to write it out like
cd c:\
cd mame
mame.exe
i cannot remember exactly how i did it when i was running it in DOS as i greatly prefer the stripped XP setup but im sure thats how i did it

cj, yes - or try out the 'alternate video adapter' method. It's in the wiki. Also, following on david's comment, make sure you know your command line syntax.
