Let's see... PL/I was the first language I wrote a "Hello world" program in (It was supposed to "replace COBOL") I worked on paper cards for an IBM system 360/75 running OS 360 MFT and HASP 4.0... A 300mb drive was the size of a washing machine, tape was king at a density of 6250bpi (that's bits per inch)... The smallest machine I worked with in College came built into it's own desk, had 16k bytes of Plessy Microsystems ferrite core memory and a single 18" platter 5mb disk. That was when DOS 1.0 was still in Bill Gates' dreams... The first PC language I learned was Intel Assembler for the 8088...
