I just picked up several of these boards and I think from searching the net they are telecom boards? can anybody elaborate on what these are and what they might be worth? they are NEC boards and the model numbers are, PA-4RSTB-A, pa4dtla, pa-8cotf. those arent all of the numbers just a few, any help would be greatly appriciated.

First one is a register card, not sure about the second but the third is a cot card for PSTN trunks.

These are cards for old NEC 2400 systems. he DTLA is interesting as not sure what it's for. Ozzie is partially correct about the TLTC card. It's for E&M tie lines or DID trunks.

Anybody have any idea of how much these might be worth??

Yeah... I don't think that the new 2400's use that style of edge connector....

But I may be thinking of the edge connectors on the 2000....

it's been a while since I've had to do anything on a 2400.
