Atari 1040ST, a 16 bit processor on a 32 bit bus, way ahead of its time.
I bought a Dell 486SX-25 at about the same time. Came with a whopping 4 megs of ram and I think 512k on board video memory. It also came with win 3.1 and as I recall, you had to go to a dos prompt to launch WP 5.1.
Oh, and a blazing fast 14.4K modem card built in.
We’ve come a long way since then.
Backed the whole thing up with floppy disks! I used to blow out the system and reload the OS and apps just for the fun of it. We called it a "clean install" and actually it was recommended that you do that once a year.
A couple years ago when I was moving to my new house, I found this system down my basement. I turned it on and amazingly it came to life. I poked around and found archives from the old Prodigy Bulletin Board - which was the pre-Free Republic meeting place. Some of the original Freepers were on Prodigy, including Jim Robinson himself. I saw old names like Karen Bixman and Judith Pedgrift. I couldn't believe the hard drive still had all that original data.
Anyway, would you believe that in nearly a quarter century of using computers, I have never had a hard drive failure? I have always religiously backed up my data but never once had to restore a failed system. Maybe I'm just lucky.
