File comment: These are essentially the same board but one has pins on the back the other does not.

Apple cpu. I’m debating. It’s a variant of PDS. Just seems like the best option

Peripheral

Left low telco right peripheral.
They both have connectors. One on the left is a zif wire connector and one on the right is a lif ribbon edge. One on the left has higher grade components, and more of them. Plus the higher quality gold pins of the wire connector. I would put that one in low telco.

Im sorry I may have confused the situations with one having pins and one not.
O and then i realize i have 3 versions of these.

These are separated into 3 pictures front and back. The picture with the side view is the pins I mentioned previously.

Not that this has any bearing on grade, but the possible “Apple cpu”. If i remember right those were came from a mobile security system like on school busses. The HDD was inside a housing, it was channel mounted in the bracket and the boards were mounted to the outside of the bracket with a ribbon wire going from the board to the HDD.
Hope all that makes sense :)

Chris said the first board is high telco.

Low telco.

The two non-Sony ones are debatable fence sitters.

That pds board is is always an issue. With Apple (and IBM) we just go for Apple Card. And it’s done; as Apple (and IBM) covers 70-something percent of that market.
Anyone else it’s probably going to need to looked at in person. In hand.
I see a reply you just posted saying he said high telco. PDS was invented by Apple and Motorola with IBM. It’s been modified a few dozen times since by other companies’ partnerships. It’s the same premise as a slot processor, with direct bus access, and everything CPU related on a single card. Just using pins instead of contacts. Not that the explanation helps, other than pointing out that minor changes from PDS can raise or lower the value class.
