well the green boards are what medium to hi grade and the others are low grade , I box up the green boards, put the motors in a bucket, but I don't know what to do with the laser board spindal part. I have several laser printers but don't know what to do with the laser board. I just in my other post picked up like 8 big office copy fax machines and many small office home all in one printers,.... none of these are considered telecoms I guess... by the way can someone tell me if the office phones boards are telecom lol I need to research that.
