A year or so ago, I pulled these boards from, something.

I'm thinking I pulled them from some sort of floppy drive as they were in a box with like boards.

Could you tell me what classification they would be?

If not some sort of floppy drive or tape drive, then would they go as peripheral?

Thank you,

RFIII

they're all peripheral. Don't cut the fingers off, it's the boards prime reason for the grade.

Thank you Lost. I’ll be leaving the GF alone. Haven’t started cutting any at this point from anything and I don’t want to get into doing that just yet.

Can you tell me what they might have come from? I wish I could remember...

I haven’t seen this specific board. But my first guess is a scsi tape drive or some over-stuff floppy drive like zip or Jazz.
The controller on the board, I’ve only come across on sequential buffered serial bus drives. Linear transmission, like tape, floptical, etc. It could also be an early floppy like 8” or 5.25”. Or even IBM’s in-house early PC/AT PS/2 era 3.5 inch drives. Which in the earliest days were sold to manufacturers with a different board since, like many things in the late 80s from IBM, they had a different protocol in the IBM computers.
Tape drive is my best guess.
If you want to know for sure measuring the longest end can help. If it’s over 3 inches it’s not a 3.5 inch drive controller; not one predating the mid 2000s at least.

I’ll edit this if I find something more but a quick scan for the manufacturer part bring up 3 types of drives.
5.25 inch disks, all aftermarket. Some branded Chinon, others from dozens of third party manufacturers.
Including an Apple Disk II clone, and a commodore compatible.

OEM tape drive controllers,

A 3.5 inch controller for aftermarket PS/2, PC Jr, and PS/1 drives. Allowing the multiple formats of different systems to be able to be accurately read in a single “super drive”. Different disks at the time had different track layouts from different vendors for different manufacturers. I remember the idea of super drives but don’t recall ever having one.
Oh, fwiw, all current (usb) external floppy drives can read most of the disk types.

I do remember a co-worker giving me a bunch of early to mid 80s era PCs to scrap a while back. I now seem to remember a number of large (to me) floppy drives, smaller than 8” in them. I’m going to go with early 5.25” floppy drives.

Thanks for jogging the old memory Lost!

That fits. Glad to help. And glad my memory can still be sparked as well.
And if you’re under 50, or even 40, chances are you’d clearly remember an 8” drive. I grew up in the home computer revolution and didn’t see one in person till the late 90s working at a site that had an old old mainframe.
