Do you know the prices of certain items when they first came out?

Question

This is for a school project on high tech versus low tech items. I need to know how much each item cost when it first came out:
-notebook (the paper one)
-map (any kind will do, but not ones made on a compter)
-Internet subscription
-"snail mail" (stamps and envelopes)
-microvawe oven
-conventional oven

If you know of a site that lists these early prices, and has at least two of these, I'll gladly accept it.

Answer 1

well when i was young
a notebook was .25
snailmail..06
microwave. 200.00
oven..200.00 to 600.00
Internet..the first was CompuServe or Source and that was like a buck a minute at 1200 baud
