I got my C64!
And my TV!
And the power supply for the C64!
But one of these things (or possibly more than one of them) is not working, and I have no way to figure out which, because I only have one thing with RF out, and only one thing with BNC/coax/RF in, and one power supply for the commodore.
So, tomorrow I’ll hit up some thrift stores and buy some extra gizmos for testing (assuming local thrift stores have anything I can use for testing.)
Ideally I’ll find a TV and a VCR. I can use the TV to test the commodore and the VCR to test the other TV.
Plus the VCR will have RCA outputs, so I can use it to capture RF signals with my capture card.
Of course, that will only help me narrow things down. It is still possible that my power supply for the c64 is bad (it’s a new aftermarket part from c64 forever) or that there’s something wrong with the cable setup I’m trying to use.
But I won’t know anything without more inputs.
@ajroach42 You just need something with a composite output, right? Don't older RPis have a composite output?
@freakazoid is BNC just composite? I thought it was RF. If it's composite, then that explains the problem.
@ajroach42 What device has a BNC connector on it? The typical composite connector is just a slip-on style. RF is usually either two screws or whatever that screw-on 75 ohm connector is. I've mostly seen BNC used for component video.
@freakazoid The TV has BNC input.
The C64 has RF output over RCA.
So I stuck an RCA to BNC adapter on the end and got no result, leading me to believe that something in the chain is busted.
GOing to hit the thrift store after this all hands and see what I can find.
@ajroach42 Oh, right, the composite output requires the DIN cable. The RF output needs to be hooked up to the cable or antenna connector on the TV, which will probably either be screws (easy to just cut a cable to connect to those) or an "F" connector.
@freakazoid Right. So I have the RF output + an RCA>coax adapter, like I used for my Atari 2600.
But the TV I got only has BNC inputs, and appears to be non-functional.
So I'm going to get a different TV and try that.
@ajroach42 Ah, ok. What TV is it?
@freakazoid It's a little sony Triniton PVM. Originally part of a mobile broadcast rig.
I thought it had Coax and BNC inputs when I bought it, or I wouldn't have bothered with it.
I was mistaken.
@freakazoid So the TV does work, and is composite.
So I don't need another TV, I just need a tuner or a VCR until I can get a composite out for the C64.
@ajroach42 Aah! I'd forgotten that VCRs have built-in tuners! I remember engaging in all kinds of hacks like that back when I was in middle school.
I see a bunch of stories of people disabling their RF modulators, even to get composite out, but I wouldn't think that would be necessary. Seems like it might be a video quality hack.
@freakazoid Yeah, that's probably just about reducing interference.
@ajroach42 I'm pretty sure I just assumed that jack was composite out, since my mom got me a monitor with my C64 so I never had to use it. I still have the C64 but I lost, broke, or discarded the monitor at some point.
@ajroach42 This has convinced me to get a new monitor and I found one for <$200 with free shipping on ebay so I bought it ;-)
