First photo; talk about strange!
Don't see these often!
The ram blanks will get telco in most cases.
The left board, I believe I see fingers for a peripheral rate, if not midgrade
The top left small board also goes in telco in this case.
Bottom right as is is peripheral. A serial board. Do NOT remove anything.


Small socket. The controller sits in the small dip socket. Ram/rom goes in the small socket. Plenty of expansion ports

Same board I believe


These will need to be reviewed on site. If the contacts (silver grey fingers) are gold it's definitely in peripheral. silver or nickel you'll get peripheral. If they're tin it's midgrade but the solder comes into play on these as well (tin contacts with silver soldier can edge into peripheral rarely.

This is a rare example I point to where if the fingers are gold and you have a lot (looks like you do) you're better off cutting off any gold fingers and taking the midgrade board hit as the fingers are heavy and thick and worth more as gold fingers.

I see now first pic left is a single board.
Telco

The last pic is going to have to be reviewed on site. My guess would be peripheral from experience but it needs to be scanned to determine what the silver and grey metals actually are. This stuff always throws them for a loop.
Again you're probably, but not definitely, in a better financial situation if you cut the fingers on these when they are on BOTH sides, but not single sided.

First pictured attachment, and your second, third are all from a piece of older Hewlett Packard equipment. They are full run gold plated boards. If you gently scratch off some of the enamel mask from the covered areas of the board, you will see the gold plating below. These are really good boards.

That second board isn't going to go any higher than small socket. I took the rather thin plating into consideration here in boosting it to small socket in the first place but yes those are older boards.
