O_o That might be one of those v9990 evaluation boards, how cool is that?

(Also pointless if you have a GFX9000, but I think collectors will go into drool-mode over this one Wink)

Woah, is that the famous PCB of the MSX3 prototype? According to seller description, there is not R800 on the board, just V9990, Z80 CPU and I/O.

In the photo i cannot see any v99x8 on board, how they assure msx2 compatibility at HW level?

No!, this PCB hasn't a spare socket for z80!...note that the socket is 14x2DIL so, it is for ROM.

surely it must be controlled by mean of that bus. OR

what chip is that other surface chip near of the brown connector? a msx engine maybe????

I needs pictures with more resolution!!!!

but with that i can see, the bus connector, has the pin 10 grounded, and it is BUSDIR!!!! .... shit seems that it is not a MSX bus connector.

but anyway i needs picture with more resolution to do a correct analisys
