Why Sierra Hated the Commodore 64

The adventure game that started it all... and left Commodore users behind.


For years, King's Quest was the "forbidden fruit" for C64 kids like me. Sierra On-Line famously refused to port Roberta Williams' masterpiece to the Commodore 64, claiming the VIC-II chip's color clashing couldn't handle the art style.


While I was stuck with blocky graphics, Tandy 1000 owners were exploring Daventry in glorious 16-color TGA graphics and 3-voice sound. 40 years later, I finally got my hands on a Tandy 1000 SX to experience the game the way Sierra intended.

👇 ABOUT FLOPPY DEEP DIVE 👇

Hey, it's Tom from Texas! Floppy Deep Dive is dedicated to Real Hardware and Real Nostalgia. No emulators. No filters. Just the crackle of the CRT and the mechanical grind of the disk drive.


I make these videos for the folks who spent Saturdays swapping floppies and still get chills when the SID chip kicks in. We dive deep into the Golden Age of PC gaming, reignite the classic 8-bit wars (C64 vs Atari!), and hunt down the rarest software on earth. Whether you're Team Commodore, Team Atari, or just miss the 90s, you're in the right place.


The Mission: Preserving the sights, sounds, and "craptacular" quirks of classic computing before they fade away.


🕹️ What You'll Find Here:


The Hardware: Commodore 64, Atari 800XL, Amiga, 486 PCs, and more.


The Wars: C64 vs Atari/NES comparisons (Let the debate begin!).


The Hunt: Deep dives into mysterious floppies and forgotten games.
