Original, tested and working Konami / Stern 600 arcade game circuit board from 1981. This fairly hard to find boardset uses the Konami Classic pinout and a vertically mounted monitor. This boardset has the 600 version of the game roms installed, although they are labeled "Turtles" with Stern stickers on the roms. We suspect Stern released some Turtles game boards with the 600 rom set installed. 600 is similar to the Turtles release, but game play does differ a little. We suppose you could swap in Turtles roms to convert it to the Turtles release if desired.
It has been tested and works fine (was recently repaired, a few sockets replaced on the sound and CPU boards, in particular).
