“I think the BIOS was 4KB, not the main memory.”
You must be right: I didn’t read the full article until after my post and it said 64KB. I’m assuming the reporter’s fact-checking is far superior to my memory. What I do remember is the process of having to swap out disks and the sometimes painfully slow process of its writing to those old 5-1/4” floppies.
And they were SS/SD floppies, too!
But then again, I have to catch myself and remember that it was better than casette tape, paper tape, or cards. It almost seems like technology improvements have slowed down since then, as those were really huge advancements.
