This is a very unique IBM 5170 that has been upgrade to a BGI/Ariel Xcelx 286/287 CPU. There are detailed pictures and some old ads I found about this piece included for you to consider. The system has piggy back memory as well, and a hard drive.Unfortunately there has been some physical damage to the switches on the rear. These could be easily repaired but I have included images of the damage.The system has a bad power supply (no power without any connection to the system) and I was not wanting to delve into the repairing of the 287 board so this will be as-is.
Great, unique, and fully loaded piece from the era!
