I guess I am old
My first computer was a Timex Sinclair 1000 with 2kb of RAM. My first real computer was a Kaypro IV running CP/M with a 2.5 MHz Z80 CPU, 64kb RAM, 2 single sided 5.25" floppy drives, and a built in 80 column 9" monochrome green CRT. I learned to program in S-Basic, Dbase II, and Pascal on the Kaypro. Later I became a Commodore, Texas Instruments, and Atari computer dealer while programming on the side. I remember when I was introduced to C. It was a revelation. I wrote several program libraries, some of which are still in use. A couple years ago someone tracked me down to see if could modify I utility I wrote in C to blank the screen while another program was running. Apparently someone was still running a program that used the library I wrote. I told him it was so old it was not safe to run in the Internet age. I used arrays to hold binary self modifying 8086 code. Big no no nowadays. I was surprised it still worked at all.
