Thanks for the photos! Were all the '775' cards produced for the west labeled as 'IQ', including the ones for the US market? I have never seen any mention of photos of the 'OZ-775' yet.

It seems so. Bob, do you remember?

Is your OZ-707 card also a prototype? Its back states that it's OZ-770 with 64 Kb RAM even though the label on the front lists only 32 Kb.

Yes and no. As you noticed, production was not fully ramped up yet, so they used another card's back, but the PEEK command in this card refuses to read the organizer's password, so the firmware was either fully baked or very close to it. I suspect that only a handful of cards like this one ever existed, as final beta-testing units. Bob, does that sound right?
