Title: TV to arcade monitor conversion?
Post by: vidmouse on May 19, 2008, 10:25:09 am
Have no idea if this is even possible, but I thought I'd ask the question.

I just scored another cab off ebay that is complete except for
a monitor and a back panel.  Was wondering if I can take my
old 19" tv that only has coaxial cable inputs and turn it into
a monitor for this cab w/o really MAME-ing it?  (it comes with
the oriignal boards and roms but don't know 100% if they're
working)

As a second option (ie if they don't work), I could MAME it but then I'd need a way to
hook into the coaxial cable inputs -- some help here would be
great too!

This is the cab I got:

Thanks for any help!

It's possible, but not exactly easy.  You will need a chassis to convert your TV to an arcade monitor.  Something like this:

Has anyone tried one of these 8-liners chassis?
I would be interested in a review or impressions.

There's a big thread somewhere in the monitor forum.  Rick from niemandisplays.com may also be able to help.

Thanks.  Just taking a look at it ,  it seems more than what I'd want to get into.

Another thought, maybe if I MAME it I can use my 19" as a monitor by
using an RF modulator to accept my PC's s-video input.  ANy better
way to do this than buy an RF modulator?  (note my tv is old, has
only a coaxial cable input)

What did those old game boxes do that came with Atari's?... seemed like you plugged in a single cable  to this box and you could screw in the box terminals to a coax cable converter...  can't remmber how it all worked though.

Yeah that's an RF modulator.  It's pretty much the worst possible way to run a video signal to your TV.  You will probably want to avoid that route.  Personally I wouldn't go any less than S-Video for MAME purposes.  Maybe you could try your local craigslist or Goodwill type stores.  Used CRTs seem to be going for cheap these days.

You know, I remember the picture looking pretty decent back then, though. Maybe not really?

Yeah, I remember it being not terrible either. Then I tried it a few years ago. It's really not bad if you're used to playing games in a snow storm. I also didn't feel like VHS was so bad when DVD came out, but it's damn terrible. Then again, the tapes are getting older as well.

I sometimes wonder if the more modern advancements will seem like such tremendous leaps in hindsight, even though component and dolby 5.1 are more than enough for me at the moment.

I'd advise away from monitor conversion if at this stage you know nothing about it. I'd rarely advise even if you were competent at electronics. For such a cab with a broken monitor, I'd MAME it into a nice multi-game upright machine. If all you have is a co-ax input, you should get a step-down unit like we use to have in the UK back in the day. Before we all had SCART TV's, if we bought an input SNES or NEO-GEO we had to buy a converter that changed a SCART signal to co-ax. No idea where to get one though.

Thanks for the warnings.

Actually, I do have an RF modulator, but it's not exactly a spare... it's running
on my family room set right now w/ an older TV that also has only coax inputs
(was my wife's unit before we got married, go figure)

I might just test out an s-video conversion and see how much I can stand.
Probably not much.  :)

i have an rca fr modulator with s-video it doesn't do a bad job it looks good it you use scanlines. tested it on a 13 inch tv, 50 inch projection and a 30 inch tube tv looks best on the 30 the text is a littl messed up but all in all  if its all you got it works good

Forget the TV if your are going with MAME.  Look around on craigslist and visit some local electronic and computer repair places.  You will find a 19-21" pc monitor for less than 50$, often for free.

I'm guessing at the monitor size right now.  That's a good idea, we'll see what it is when I get it on Friday.  Could be a 17-incher  (if so, should I keep the bezel art -- whaddya think?)
