Commodore64 was rocking along with 64K ROM (memory) and didn't have a hard drive. I believe it was using a data player which looked like a cute little cassette player.
I know because I was using a screw driver to play with the head to freezeframe hack into games to modify their code when I was like 11.
I remember playing this side scroller game called Karateka where I ended up enlarging the character's head by x3. He looked like a bobblehead! I was laughing so hard I couldn't play the game.
My dad thought I was mental......he was kinda right.
I still have a working Maxtor or Quantum brand HDD with a capacity of 560 MB!
Dude111, let me know if you are interested in upgrading your system, I could send it to you!
