Dead AIM 65??

Anyway, back to the original subject. There is no magic bullet to bring these older machines back to life. Some of the things that can help are, not in any particular order: 1. Volt meter 2. Logic Probe 3. Set of schematics 4. Oscilloscope 5. Soldering iron w/ solder 6. Parts to swap 7. assembler/disassembler 8. EPROM programmer 9. Source listing 10. Needle nose pliers 11. solder sucker and/or solder wick Also, one needs clear logical thinking ( not all that common in the world today ). The debugging procedure is in specific order: 1. gather symptoms and observations. 2. Form hypothesis of possible cause. 3. Test to see if hypothesis is correct. 4. If problem not found, include results into observations of step one and repeat. Dwight
