This computer has a very nice case and works fine. It has the original revision 4 motherboard dated 8024 and the Serial number on the bottom is #81717. The rev 4 motherboards are becoming harder and harder to find and were mostly installed Apple IIs and in some of  the early II plus computers. The keys have been checked on the keyboard and are working. The power supply is a 605-5703. Comes with a Microsoft memory card in slot 0 as shown in the photos. No monitor included. This computer will make a great addition to any vintage computer collection. Please ask if you have questions. Due to the age of this computer, I am selling it As Is.
