The SYM-1 is a 6502-based single-board computer produced by Synertek Systems Corp in the mid 1970’s. I’ve had one floating around in a box for many, many years, and after a recent foray into the world of 6502 assembly language programming I decided to pull it out, dust it off, and see if it still works. The board I have has a whopping 8KB of memory, and in addition to the standard SUPERMON monitor it has the expansion ROMs for the Synertek BASIC interpreter (yet another Microsoft BASIC) and RAE (the “Resident Assembler Editor”).
