Mega CD II Working Sample No.1 + Bios Ver 1.11

I got this from Germany, it also came with a sample MD2. Buttons had been painted red at some point, but mostly worn off now. Possibly made to look a bit more like the European version prior to release. This one from Funai, dated 1992.09.25. Bios is dated 92.05.01, it still has the appearance of the Mega CD I bios. Actual Mega CD 2 didn't release until 1993.04.23 in Japan (bios 1992.12.17), later in the west. It's quite close to the initial JP release, but some differences, such as not having the connections for the extension plate.

I'll be interested to hear of what differences this has to Mega CD I bioses.

 

Wow, that is early. Great pics, thanks.

 

That is an amazing find I must say! Loading it up on my ever drive to see what it does

 

Yeh great score, thanks for sharing.

 

Edit: I've just noticed that the original bios link is dead .... it's still available here if someone is searching for it.

 

Cool find, dude!

 

Really interesting thanks for sharing!
