They were old cassette players! I asked at Target if they had cassette players and they laughed at me.
The thing I really miss is carbon ribbons for my typewriter. I can only get fabric ribbons now.
The carbon ribbons made beautiful sharp letters. The fabric ribbons make fuzzy letters and I have to retype to get them dark enough.
Luckily I only use the typewriter mostly for checks and envelopes.
I am weeping with nostalgia now. I miss my portable electric typewriter in its vinyl case.
Good luck finding the ribbon. Those people on the other end of recieving must be fascinated by your typewritten checks. I know I would.
