Please help ID these PCBs. Thanks!

1, low telco, might be peripheral because of size and empty area population.
2, small/metal color MoBo
3, low grade
4, mid grade
5, floppy drive? If so, peripheral
6, mid grade
7, low grade, remove white tape, if chip underneath, mid grade
8, mid grade

1 peripheral
2 small socket
3 midgrade
4 gold pin connector
5 gold pin connector (not floppy)
6 midgrade
7 low
8 midgrade, could get upgraded if pins are gold.

#5 isn't a floppy?

I'm pretty confident it is, let me get your 2 cents Lost

Way to small. It’s some sort of serial board though.
I can’t match it exactly. From part number either. I have 18 different items in the DB with that number. 15 with photos. None look like that. The other 3 are a speaker part. With only 4 pins and three power pins.

Best guess is a cable interconnect. Of some sort.

Regardless floppy boards get peripheral for two reasons. A well know hard to reduce controller IC type. Even the great Woz couldn’t skimp it much.
And standardised pins. This has neither.

Only 2 drive boards I’ve ever seen with that few pins was the twiggy. Apple’s FileWare.
And the original Amstrad 3” controller.
Both were epic failures in use. Neither would make peripheral rate and both are extremely rare expensive parts that would be better on ebay in ANY condition.
It’s not a twiggy board. I have one. And every AS10 board I’ve seen has the ceramic controller on the side we’re looking at here. Though it /IS/ close to that board’s layout.

I thought for sure it was a floppy board.
I recognized the blue clock controller and the 4 pin power plug with the ide pin plug. I can see the 2 ribbon connectors for the motor and reader too.

I'll have to post some floppy boards I have because they're small like this and kinda of bare n empty population.

One day I want to sit down and have a conversation with you Lost. Pick your knowledge and enjoy some computing nostalgia. You have an immense range of everything in this field I want to know too, haha.

I posted another picture of 7 without the tape and some more pictures of board 5 if it helps solve your mystery.

Let me know if I should post more pictures of these. Thanks!
