My first computer was...
But not compared to today's systems. My first computer ( that I owned / had given to me by my parents ) was a C-64 with the Tape-Deck unit to plug into the "User Port". I started a year or two before that with the neighbors ZX-80 and then TRS-80 Mod III.
I actually went to computer camp for two weeks one summer where they had TRS-80's. Any one else brave enough to admit to that level of Geekdom?
A few years earlier my brother's High School was gifted a Dec Mini Computer, two DecWriter 100's and a tape Punch machine, with no software. They got to bootstrap the machine from zero. The system had 16K of memory (Huge for that time) and was 8 Bit. The coolest part about that system was the toggle switches across the front. Address Bus, Data Bus, Read/write toggle. and 8 leds to display memory contents. They had to programs to drive the tape writer, a tape reader, an editor, a compiler, drivers for the DecWriters for human readable output, etc.... How cool was that? Oh, I forgot to mention, the thing was about 2.25 feet square and stood about 6 foot tall, and was much heavier than a refrigerator.
