Vintage slide projectors


Recommended Posts

I have acquired a large number of 35mm slides. Many are contained in Sawyer's Easy-Edit trays, and the others are in GAF Roto-trays.

.

Is there a slide projector that will handle both styles of trays?

.

Heck, while I'm dreaming, what's the chances there's a projector that will also take Slide Cubes?

.

:rolleyes:

Most trays are much more bulky and awkward to store than the slides in metal group boxes.

I wouldn't worry about getting projectors to match obsolete slide trays.

Absolutely agree, have a lot of both. Problem is, those in many, many trays are the ones that get projected on occasion. Those in the boxes, not so much - viewed on a light table or hand viewer prior to scanning. Best storage, IMO, depends on best method of use for the particular individual.

Should be easy to find obsolete slide trays and projectors on E-bay. My "go-to" slide projector is the Kodak Cavalcade 510, which takes those proprietary (I think) straight trays. But, they are plentiful online so I'm not worried. Lots of folks are dumping their old gear these days.

My parents have a Sawyers projector.

 

Some years ago, I got about 20 of the rotary trays from a garage sale, then

mailed them. (I was away from home, at school, and about 30 years ago,

and about $1 for all 20 trays.)

 

The mailing was more expensive than I thought, but it was still a good deal.

 

When I first got my Kodak projector, I would buy trays for it for a while.

 

Then when I got the stack loader (maybe about when it came out), and group

style slide boxes, I put the slides in those. Now I mostly don't use the trays,

but also didn't throw them away.

Reminds me, when my father first bought the slide projector, about 50 years

ago by now. (Not so long after Quartz-Iodine bulbs came out.) He told me about

flying spot scanners that would allow for viewing slides on a TV set. I suspect

that they were then, and still are, too expensive for ordinary home use. That

was before the digital technology that makes digital display so easy to do now.

 

It takes a few megabytes to hold a full color image, to display on a video monitor.

Back then, the largest mainframe computers had about 3MB of core memory,

so it wasn't likely to be available for home use. But the flying spot scanner can

continuously rescan the slide at the CRT refresh rate. You might still need three

photomultiplier tubes, though, for the detector, so out of home use price range.

There is a stack loader for the Sawyers/GAF projectors. My father had one from

close to when he bought the projector.

 

I think it took longer for the stack loader for Kodak projectors to come along.

 

When I got my Kodak stack loader, it came with slide clips, which are little

metal brackets that hold a group of about 30 slides, and can even stay on

the group through the stack loader. It makes it a little easier to switch groups

on a long show.
