I get a nostalgia feeling from my old TOS single episode tapes. Some episodes i have in the older "Picture in transporter" paramount 75th anniversary edition, and some are in the newer "Comet" edition. The actual smell of the tapes after they been playing a while even reminds me of old days of watching star trek as a child. FOr a few years, the only episodes I owned were "The Corbomite Manuever" "Balance of Terror" and "The Cage". We didnt have much money when I was growing up and those episode I caught on sale.
What Gives me the ultimate nostalgia trip, is the tape called "STAR TREK 25th ANNIVERSARY SPECIAL". I still have it in good condition on VHS. If only they would re-release it on DVD. I really wish they would re-release "William Shatner's Star Trek Memories" on dvd, and film "William Shatner's Star Trek Movie memories."
