Interesting. Can one use the VGA port for video output for say the Sega Blast city or any monitor with a VGA 24htz input?
I just tried the DE15 port recently, since I thought it would be an easy way to capture footage from. I don't have a scope, but I just took crude measurements with a multimeter and unfortunately it's not outputting 0.7vpp video. Reading was hovering around 1V. 1V isn't that high that I thought it would damage any equipment so I just connected as is to a Datapath capture card. The image was super washed out. I then put it through an OSSC and set Pre-ADC Gain to 0. I captured this footage off of Dirt Devils:
Not bad. I might throw some trimmer pots on the video lines if I mess with it more.
Most monitors will expect 0.7vpp from the DE15 connector, I think? Tosh PF you can set to high impedance if you swap the connector.
