The Hex Inverter is the smaller chip on the PCB(second picture in the above post). You just have to solder it to the board, not much else really. Just make sure to solder it before the eprom or the eprom socket.

I know this is an old subject but I just stumbled upon the review of Z-blocks at Atari HQ and read a few posts about here.... Has anyone found out what happened to this game?

I don't have an Amiga 1200 for trade but you wouldn't by any chance consider selling it for the price of a used Amiga 1200 with accelerator card? Thanks
