I just picked up a small CRT tv from my parish with hopes of connecting it to my computer, either my modern one, or even my IBM PC from the early 80s.
I looked at the back of the tv and the only input it has is a coaxial sort of thing, for antenna or VCR or something. No svideo, no other inputs. Just that. My computer has vga and thats pretty much it I think. Is there any way I can get this rig going? Is it a good idea, or should I just get an actual crt monitor? Mind you, I'd rather spend the least cash for best result.
Also, the input for the tv says
VHF/UHF
75 ohms
Thanks!

Ok you cant just convert an svideo or rca cable to coax, you have to take the video and modulate it as a frequency to put it on the coax. This is why you had to turn your TV to channel 3 or 4 to get your VCR to show up. The VCR modulates its video onto the frequency band that the TV sees as channel 3 or 4.
You can use the VCR in place of the RF modulator but you will still need a VGA to svideo or RCA converter and the VCR, and the VGA cable, the RCA cable and the Coax cable.
You need an adapter for VGA because it sends separate data for red, blue, green, horizontal and vertical sync among its 15 wires. The adapter takes this info and then merges it onto a RCA connection.
You will require many parts to end up with a twice converted image that is probably not going to look good, and it is not going to save you much money if any at all.
I would look for a used monitor, a flat panel for the early 2000s would be leaps ahead, even an old crt monitor would be better.
