The easy way to do it is get a VCR to go with the TV. VCRs hold up really well with age, better than top of the line cassette decks and you can often pick them up for $12 or so.

The earlier VCRs definitely did. We had either a Sony or a Toshiba (can't remember exactly) and that thing lasted decades with heavy use. It even survived disassembly/reassembly by a horribly underqualified kid (me) after having a PB&J sandwich shoved in the front (which was not me). Taking that thing apart was absolutely fascinating!
