I took used an Ohio Scientific (C1P I think). It had a "massive" 4k bytes, and I wrote a chess program in interpreted BASIC for it. This was about 1980. When I had a co-op job during a break in college for GE, a boss there gave me some used memory chips allowing me to upgrade it to 8k! Wow! To fit the program I had to use direct peek and poke statements (to allow byte access since and INT would be too big!). And you had to put multiple lines together since breaking them up took too much memory. Even spaces took up memory so it was all squashed together. It only did 3-4 ply searches. I remember after a long drive on icy roads, a chess playing friend, very tired from the drive, agreed to play it. And for the first time, my program won a game!
