I used it for 4 months and then stored it in my closet. It is in great condition and still seems to work perfectly.Powers up fine as you can see in the picture. It includes a hard copy schematic that is 35" x 23" large, an illustration booklet, manual, it also includes the complete Heathkit Microprocessor text books 1 and 2, and also includes the Heathkit student workbook. There is some writing in the books as I used them for class but all of the information is there and in great condition. If you have any questions please don't hesitate to ask as I answer all questions promptly.
