![PC Archeology: A left for Dead IBM PC 5150 with a treasure hiding inside 🕷
Its time for another episode of PC Archeology! This time we have a IBM PC 5150 that was picked out of the recycle bin, about to be shredded. I thought this was just going to be another run of the mill PC, but you never know what you might find inside.
