Sharp PC-1500 Cartridge for debugging

For debugging purposes (and also for playing around with memory chips on a bread board) I’ve created little breakout boards for the cartridge slot on the bottom of Sharp PC-1500s/1600s.

Typing on the PC while having cables connected to the cartridge is a bit annoying as I tend to pull off the cables when turning the PC around. I’m currently figuring out a better solution by using ribbon cables instead of the pins. I will update the post as soon I’ve managed to make photos of the modified version.

  1. Hello Kai,

    That’s a real good idea and a good final product.
    May i buy 2 ?

    I’m surprised that you test it on a so rare PC-1500 with serial number beginning by 2000xxxx. It one of the firsts 10000 produced and maybe a A01 ROM version. 😉


    • Well, why shouldn’t I play around with the PC-1500? I’m a computer scientist, not a collector, and think these PCs should not rest in boxes or behind glass… 😉 — Kai
