I have heard of the ELF but never used one.

My first "computer" was a Radio Shack "trainer" with hex keypad, two-digit LED 
and a 4x4 matrix LED "screen"...

My first REAL computer was an Ohio Scientific (OSI) C4P.... 6502 @ 1MHz, 8K 
ram, BASIC in ROM, cassette storage and 16-colour 64x32 character text-only 
video... Bought in 1981. It was closely based on the earlier OSI  "SuperBoard 
II" single-board-computer. That held me for a while, while I learned 6502 
assembly language. We used PET 4032's at school and a Wang system with 
card-reader.
