Flashback 2 Help needed

[MattMan]

I have a flashback 2 and have been doing the cart mod. I have the cartridge part all wired up but I'm very confused on the switch part. I don't know how to wire it up correctly.

 

I was fallowing the guide over at http://www.atarimuseum.com/fb2hacks/page2.htmand have the same board version as they have pictured but the part where they tell you how to wire the switch makes no sense to me. I was searching everywhere for some kind of wiring diagram that would clearly show how to wire a switch up. Is there anyone that can help me out with this part.

 

I know my cart port works correctly as when I was testing if i powered on the unit with two wires touching and then quickly removed them my game started up. Not sure what the hell I did I think I had j3 wired to c4 and powered the unit on while holding those wires to IC2 then quickly removed them from IC2 and saw my game. Something like that, anyway the cart port works.

 

Any help on how to wire the switch would be great.

Think I figured it out. Here is what I did. Seems to work, hopefully this helps someone else out.

Finished product.

 

 

I'm guessing no one cares about these any more. Or anyone who wanted to mod these did so long ago. I'm late to the party.

I like the side mount!

I like the side loading cartridge too, very clean and a little bit Intellivision. Nicely done.

This is so cool. I'm so tempted to begin the journey...

I did the mod on my Flashback 2 but with a top mount. Never thought to put it in the side, what a great idea!

 

Was a bit disappointed with the Flashbacks compatibility though, so still use my Jr...
