I've had this since 1982-83. It's not booting. Following advice I got a chip puller and started to re-seat the ram. To my surprise I find a spider nest? In addition, I took a close up of one of the RAM chips and you can see the years of neglect.
Not sure if I can revive this but I'm going to try. When booting I hear the beep and I get what you see in the picture on the screen. Any advice would be helpful.
Fixed- All memory was pulled, cleaned (eraser, contact cleaner and light sand paper) and reseated. Still got an error at boot up. After reviewing another post on this site with a similar issue, I decided to pull ROM-D0 again to inspect. This time I noticed one of the metal legs was clipped. I corrected this and now it boots to a prompt- like it should.
Thanks for the tips and tricks.
