Cheers mate! I think so too! It was a bit of a vintage rarity I gave up but it was with a very dear friend from Japan and both parties are very happy!
Is your Zorga the same?
I also got the earlier Zork Machine on loan, I think it's got an OC75 and 2 2G374s. Sounds great too. And is that the battery door on the bottom? No, it's a circuit viewing and appreciation door! Haha you have to take the whole thing apart to change the battery
