Hi. I dug up a few cards today out of storage and I am not certain what some of them are for. Does anyone recognize any of these?
Any help is appreciated! Thanks
This one has the writing MICRO WORKS DS-65 EPROM II written on it. The only IO connection are a single three-pin header.

This one has the writing AMDEK written on it.

This card really doesn't have much writing on it at all.

I am fairly certain this is a simple dual floppy drive interface card.

This card says Apple Dumpling-64 and Microtek written on it and has a Centrics cable attached to a header. My guess is a printer interface card.

This card says Pro Grappler and Orange Micro written on it and has a header in the top right.

The Micro Works DS-54 is an early digitizer card. You can read a little more about it in the this article:

I'm not sure about the Amdek card, unless it's the adapter for their 3.5 drive.
Card 3 is a clone of the Microsoft Softcard.
Card 4 is a clone of the Apple Disk II controller
Card 5 is a Dumpling parellel printer interface with 64K buffer
Card 6 is a ProGrappler parallel printer interface
Great - thanks for the info sfahey!
I do have some other digitizer hardware, including the camera, so not too surprised to hear about the digitizer card.
Card Number 1 (From Google Search)
This early Apple II video digitizer (the DS-65 Digiselector) took a regular video input and…well, digitized it. The result was a 256×256 pixel greyscale still image that you could manipulate on your Apple II. In an age before consumer digital cameras, this was quite a novel feat of technical wizardry.
It sold for $349.95 in 1979, which is equivalent to $1,054.24 in 2010 dollars. That's actually not too bad.
