The power button does NOT work so as soon as you plug it in it begins to power up and you cannot turn it off without u plugging it or through its shut down options. This vintage IBM Personal Computer 300PL is a classic piece of computing history. With a model number of 6862, this desktop is perfect for collectors and enthusiasts alike. IBM is a well-known name in the computing industry and this particular model is a great representation of their early work. This comes as is without any additional parts or accessories. It was not modified in any way, and for those interested in vintage computing, this is a rare find. Its vintage classification makes it a valuable addition to any collection. I removed the broken housing piece that surrounds the disc drive so it will not have that when you receive this unit.
