WHOA .... ok I am just a mere youngster then.....
The first computer I worked on was a DEC PDP-8.
The first computer I owned was an Altos 586, which I bought used in 1986. I was working as a programmer for a database management company, and they used an Altos 2086 (80286 processor.) I bought the Altos 586 from a church for $1000, and it had a 10MHz 8086 processor, 512MB RAM, a 10MB hard drive, and ran Altos Xenix. No graphics, it used serial terminals, and it came with a pair of Altos II terminals (Wyse 60 equiv.) Since I needed to load the Xenix development system on it for work, I replaced the hard drive with a used 20MB drive for another $1000.
