I am building a "retro rack" of older systems. I purchased an 8 way composite switch so that I could simplify any switching process...I intend to run the composite cables from the SNES, Genesis, etc right into the switch, and to run the switch out into my A/V receiver. 8 systems at the press of a button (assuming the AV receiver is on the right in, natch)
My problem comes in converting the coaxial RF signal of the Atari 7800 and the Turbografx 16 into composite so I can plug them into the 8 way composite switch.
My plan was to use the old fashioned VCR trick. I figured on running the two systems coaxial signals into a 2-into-1 line combiner (the systems will never be on at the same time so I figured why bother with an A/B switcher, plus I want to keep the switching process between systems as minimal as possible) and then running that single coax into a VCR which will demodulate (I think that is the right term) the rf signal into the red, white and yellow composites.
Thing is, I don't have a VCR anymore. Don't have any tapes, and don't intend to start watching tapes again. So unless I hit upon one at the recycling center (read: local dump) I am gonna be dropping some small amount of cash on getting one, and I'll NEVER be watching tapes on it.
So is there any other way I can do this process semi-economically?
I looked up RF DE-modulators which seem to do the job but didn't find any sub 80$. Which is more than I am inclined to pay since that is more than I paid for BOTH systems combined that I am trying to convert! Are there cheaper units out there I am missing?
Would a stand alone TV tuner with an RF in and composite outs do the same job? These seem to be far easier to find and far cheaper than a de-modulator.
(My TV DOES have an RF in that I could run a long coax cable directly too, I simply don't want to have to handle these two systems differently than the other six. The whole point is a clean, uniform installation with common sense operation--not "oh these 6 work that way but these 2 work THIS way". Plus in that case, the systems sound would be coming from my TV speakers and not through the receiver, and then I'd have to futz with my TV volume and input too.)
(I am aware of the Turbo Booster AV add on for the TG-16 which converts that system's signal into composite BUT I am not a picture purist when it comes to these things so a slightly less sharp RF picture is OK by me--and the Atari 7800 is RF/coaxial or nothing so I have to deal with this issue one way or the other. EDIT: before someone points out the composite-out mod for the 7800, I am aware of that too. But it's beyond my tech level and nearly as expensive as a de-modulator.)
ANY help or advice is MUCH appreciated! If I am explaining something poorly or am confused on how these signals work please let me know...the last time I hooked these things up...the TV had screws on the back!
