Most Boards are old pre2000s and some maybe early 90s boards. All are from medical hardware. All are front and back except #3 which has 3 of the same.

#1, 4 and 5 look like low grade telcom to me because of all the capacitors. 2 and 3 could make high grade telcom, but I am not sure enough on my grading skills yet. The difference seems to be the density of ICs and lack of heavy stuff like capacitors and ferrite/copper windings.

Hope someone else will chime in to clarify.
