Game Room is Back (with compromises)

I found out that the NES outputs to both RF and RCA simulataneously.  So now the PC monitor works with the array but only for the NES.  The Intellivision, Atari 2600 Jr, Sega Master System are only connected to 3 TVs.  It took a while to figure this out.  Grok says I need a demodulator to connect RF to RCA.  Modulators connect RCA to RF.  Plenty of those online but not what I needed.  When one comes available I will install it so all the retro consoles drive with the green monochrome display.
