I'm old enough to have saved and loaded data with a cassette drive (i.e. a random ass tape deck with a special cable attached to the computer) on a TI-99/4a. You had to set the volume level the same for recording and reading or else it wouldn't read correctly. Get off my lawn.
I remember Parsec from a friend's house but I didn't have that one. I had Jawbreaker and Hunt the Wumpus, and the extended BASIC cartridge. I was a party animal back then.
