IBM 5160 XT
It was introduced in 1983 and, like its predecessor the IBM 5150, it was available with either a CGA colour video card or a monochrome (text-only) MDA video card. It shipped with more RAM (128K) on the motherboard and had 163W power supply to better support the supplied 10MB or 20MB hard disk drive (increased from the 93W PSU used in the 5150). The (mostly unused) tape port mysteriously disappeared - a sign of the times!
The 5160 also featured eight expansion sockets instead of the five that the 5150 had. This was accomplished by reducing the space between each port and as a result, some early PC expansion cards will not physically fit in the newer 5160 model. Slot eight was connected to the system bus in a different way to the other slots and had special signal timing requirements - not all expansion cards are will work in the XT slot 8. This different slot was not present in any other IBM personal computers.
Our 5160 XT is complete in its original box with the 5161 monochrome monitor and keyboard.
