1. Remove the faceplate, high Telco
2. Is a gold finger card. With bracket or without if you remove it
3. Gold cap chip board. If that's a metal bracket/support on the side, remove it.
4. Not sure how much of the board is cropped out of the picture so not sure on grading.
5. Remove the Dallas box, has a battery in it. Looks like two boards, if the smaller board can be removed, if only so we can see what's on the other side and under it on the big board, please do. The purple ceramic CPU, is it socketed or soldered on? If socketed, pull it to check for a gold cap on the bottom. If soldered, you can carefully drill one or two small holes on the other side of the CPU to see if there's a gold cap.
Board 4 (sorry file had to be compressed to upload)

for board 5, if the LSI CPU has a gold base (I believe it does) how would that grade? under the small board is a few more IC's, non ceramic
Was also curious about these, GFC with some (I Believe) SDR slotted.
