My Challenger 1P

Here's a picture of my first computer, the Challenger 1P.  This is how much it cost.  It's twenty years old now, but fortunately still operational.  It's the machine I not only wrote some of my first BASIC programs for (a sample of which is included with the Virtual Challenger 1P), but for which I also wrote my first "commercial" application: an interactive 6502 assembler/disassembler, written entirely in 6502 machine language, complete with typewritten listing.  It was sold through a shop in Oak Park, IL, called Bill's Micro Service.   Check out the contract.  It earned a little money, but I was just glad to have the opportunity to learn and share my work.
