Very cool! That's the era I came up in.
If you don't mind me asking how are you digitizing the slides? I have several that I want to do and it would be a lot of money to pay someone to do it.
I am using a projector and just taking a pic with my phone. It working pretty good just time consuming. It is expensive to get done by Costco. Its like $30 to do 64 slides then .32 cent per slide after that and I've got hundreds id want to do.
