Does anyone know where I might see the catalogs of all selections available for these cartridge tape formats: Revere Wollensak cartridges, which could be stacked 15 high. (c1962-5) RCA Cartridge tape player (1958-64) Orrtronics (c1961-2) I just want to know what was available on these formats.
Good luck, I don't know much about the oddball formats, here's some places I found just glancing around Look through old issues of Tape Recording on www.WorldRadioHistory.com https://tangiblemediacollection.com/ https://mastodon.world/@tangiblemediacollection Reach out on other forums like audiokarma.org or tapeheads.net
