Ah, those were the days!

BASIC (TRS-80 Model I)

1995–

I picked up a TRS-80 Color II in 1995 or so, just for fun. Still pull it out occasionally.

C++

1995–

TI-BASIC

1996–2000

I don't think I ever used TI-BASIC outside of high school when I programmed on both a TI-82 and later a TI-89.

Java

2000–2004

Used it a lot in college, haven't touched it since.

bash

2001–

PDP-8 machine code

2002–2003

Most fun I've ever had. As evidence, this program will take a number entered in binary in the switch register and return the square of that number in the accumulator (also in binary): 111011000001 011010010100 011010010011 111100000100 111101101000 101010010000 111000100001 011010010101 001010010011 001010010100 011010010011 111000000101 001010010100 111010010100 010010010101 101010001000 111010000000 001010010011 111100000010 000000000000 000000000000 000000000000

Discovered Python in college; now I use it every day at work.
