they apparently made 42 of these different radio cards back in the day, for stations in Kanto, Kansai and Tokai, across FM, AM and Shortwave radio frequencies. The system even won a Good Design Award in 1988 https://www.g-mark.org/award/describe/14593
you can read a bit more about it, and see more up-close photos on this store page, it’s a fascinating little artifact of ‘80s Japan http://web.archive.org/web/20200407015941/https://palette.ocnk.net/product/1124 (Internet Archive link because who knows how permanent the listing will be!)
@ticky wish I had my PSP here, I lent it to my dad so he could play Pokémon 😄
@noiob that’s a funny thing for a PSP to be doing but I understand
@ticky it is but it works really well 😄
@noiob yeah! If you go to the “Internet” heading and go *up* it’s in there. The “About Internet Radio” page used to bring you to a list of stations but it seems to be broken now, but the players themselves are still up, and you should be able to find the player “prs” times on some Homebrew scene sites, or I could share them. I really ought to finish my emulator project now that their site is broken!
