I had that and then tried to remove it lol.

you can consolise a MVS on the cheap if you don't give a crap about a fancy case

I have less than $100 in mine and it outputs flawless (measured) 700mVpp RGB buffered through a THS7374

Thats a great price and I think the $120 it took for mine is very reasonable as well. I paid ~$60 for the MVS and $60 for the jamma-console kit and I still ended up with something that looks at least console-ish. I noticed the guy I bought from is selling a pre-assembled kit (minus the MVS of course) for $96.50 USD, so about $40 to assemble which really isnt bad considering it took quite a while and quite a bit of solder to put together.

When you measure your RGB you are measuring in circuit while sending a live picture to a TV or transcoder I assume. What are you using for a pattern generator to generate a pure color sine wave signal?

you measure it with an oscilloscope with 75 ohm termination, doesn't matter if it is going to a device or just to resistors. there is no sine wave involved... any source that has a pure white screen (or line) will do

I think you can still get MV-1Bs for $30US

I got the system booted using only +5V yesterday. Got a "RAM Error" a couple times but re-seating the 161 in 1 cart resolved it. Looks great and fits perfectly between my Atari VCS Woody and my Saturn.

Still waiting on controllers which have been delayed in Japan, hopefully I get my Genesis controller adapter board kit in soon as Im anxious to try to boot a game.
