First I live close to Boardsort so I will be dropping off personally. Also The boards I am posting for ID are all from Brunswick AS 80/90 electronic bowling scoring systems and I have multiples (20-100 of each) I have been reading thru the forms for about a year. Although I feel I am getting a better idea of how to identify boards I am still a bit confused.
Board 1 I presume is a gold finger card, do I need to remove the red button reset switches, and I presume the black square box in the lower left corner is a battery that needs to come off.

1. I’m not too sure, i don’t think it has enough precious metal component population on the board. Maybe high peripheral
2. Low grade
3. High telecom. If there are a few socketed chips you intend to remove because they have resale value, you should be fine if you remove them, but be conservative about this as removing too many chips will downgrade it to low telecom. You can trim the gold fingers without a downgrade
4. Same as #3
5. High telecom, I’d say don’t remove any chips or trim the fingers or it will be downgraded to gold finger card or low telecom respectively.
6. Low telecom, however, it is close to the edge of high telecom. Wait for someone more experienced to reply
