How to connect a new computer to an old Television
Connect a VGA adapter to the Macbook DVI (Thunderbolt) port.
Connect a VGA cable from the adapter to a PC-to-TV adapter. This converts VGA to video component (RCA plug) output. The sound from the Macbook can go through this adapter as well – it gets passed through to the RF modulator.
Connect the PC-to-TV adapter, using RCA cables, to an RF modulator.
Connect a coaxial cable from the modulator to an RF transformer (75 to 300 ohms)
Connect the 300 ohm leads of the matching transformer to the antenna input terminals of the TV.
