I remember when I got that first “Disk full error” on that MASSIVE 10 Meg hard drive. That was a shocker!
We sold computers for a living in the 80's and 90's. Our first was in 1982, a dual floppy, don't remember how much ram and a 10" orange monitor, cost $5,000. Everybody we met wanted one, so we became a dealer for a brand, then we built them ourselves for almost 20 years. High end graphics and cad systems, many of them we custom built for the programmers at Microsoft.
I remember when in about 1983 or 84 we put a 5MB hard drive in a dual floppy machine. Everybody that came into our store and saw it, said, "what would you need all that storage for?" Lol, still laugh about it today.
