The fine condition, hardware upgrades, included software/documentation, and known history distinguish this IBM 5155 from any other you will find. I bought the computer in 1987 from the student to whom Harvard Business School issued it and whose name is etched onto the cabinet. It served me well for two years to perform word processing (for which I bought a full version of WordPerfect) and spreadsheet analyses (for which I bought and installed a full version of Lotus 123), the original software disks and documentation of which are included in this sale. It then remained in climate-controlled storage for the next 30 years. As a result, the keyboard, cabinet, and screen are in excellent condition and working order.The power supply, CRT display, floppy disk drive, hard drive, boards and cards all are installed and in working order. Still, running the IBM diagnostic disk earlier today turned up three error codes--102, 1201, and 1703--although I cannot determine how these errors affect the performance of the computer.
