There are many lessons needed in order to work on older IBM products in order to complement even the best general electronics and computer knowledge. First you must learn a new language with terminology that is unique to these systems. Next you must learn to deal with the peculiarities of the IBM documentation. Finally, as with any old system for which current parts are unavailable, a variety of techniques must be mastered to repair or replace whatever may be defective if you hope to successfully restore the system to full operation. Carl Claunch talks about his adventures in restoring an IBM 1130.
