Quote - First computer was a Z80 based Exidy Sorcerer in 1980.  Had a whole whopping 4k of memory.  We did a modification to the motherboard and hardwired in another 4k of memory.  In those days you had to modify a tape recorder to load your programs. 

My first was an Atari 800 that I bought in 1979.  It too had 4k of memory, but did come with
a plug in cassette tape drive for storing programs.  Later I bought an Atari 800XL
from Toys R Us, that had a whopping 64k of memory and a 5 1/4 disk drive.
Then I sort of gave up on computers for a while and my first PC was some
Laser brand 286 job that I bought in somewhere around 1988.
