Got my MegaTech up and happening. At the moment, SELECT is P1-Button4 :unsure

 

Note the monitor on top of the cab, ready to become the menu/instructions screen.

 

I have 4 carts at the moment...

Columns = :unsure

Great Golf = :sleep

Super Thunder Blade = :023: even matches the marquee :D

World Championship Soccer = :078:

 

I have Shinobi on the way. That leaves 3 empty slots :cry.

Anybody have any of these gems?

 

Ultimately, I want to buy/build a MegaTech cab. They are the coolest looking upright cabs ever made. But, no room at the moment. I am looking to move like next year (maybe earlier), then I will have room.

I just noticed that by wiring up the ENTER button, you can view each game's instructions on the small monitor. :o Very nice indeed !!!

Piy I dont have a second monitor happening yet. I went to tricky dicky's for a sync separator chip, and came home with a fistfull of video encoder chips (for 10c each :D). Gonna hook up a small TV there instead, me hinks.
