Vintage 286 Clone Project – Rebuilding My First PC

My first computer, received around age 9 or so (1990), was a 286 clone made by the Korean Hyosung Computer Company.  I kept the motherboard and HDD, a Seagate ST225.  I finally got around to re-building it though with upgraded subsystems.  The original had the ST225 20MB HDD and 5-1/4 floppy.  I will likely add […]
