I'm new to the forum and never heard of Gamba till now, but I'm very sorry to hear of his passing. I was kind of curious to get to know him through his website, but unfortunately there's no personal info there.

While browsing his site, however, I did realize I'd been there before fairly recently seeking info on the "homemade grayscale adaptors" he mentioned.

Wally, I don't suppose you would be willing to share with me the info you have on that.
