@amoroso@oldbytes.space Ah, Eeems. He was a prominent figure in the english speaking TI Calculator programming circles. The whole TI-8x series used to be based on z80 and the ASM programming scene there was quite lively. This programming tutorial is, at least to my eyes, a testimony of that community's existence. I'm glad it's still there and the community's resources are still around. EDIT: and right after writing this, I wonder if Eeems wrote the guide or is just hosting it.
