ctrl-alt-rees | Atari 260ST Story: TOS Floppy Boot Process, And How Much RAM? @ctrlaltrees | Uploaded May 2021 | Updated October 2024, 1 hour ago.
The Atari 260ST. There's a lot of misinformation circulating about this model on the internet, including the "fact" that it was only released with 256K of RAM. But what's the real story behind this machine? Did it ever have 256? Did Atari even plan to release a machine with that little RAM? And what's that floppy-based TOS boot process all about anyway?
Join me as I find out!
