We removed the RF modulators (yes 2 of them!) because they are useless, just using composite video instead. Verified that Peter's Microbee monitor with amber screen works. Inserted all chips except for those to do with RAM and the S100 bus. I supplied a replacement 2513 character generator as the original was faulty. Found that at least 8 chip sockets are faulty. Peter will replace these, very carefully, as the board has hundreds of incredibly thin tracks on it. Showed him my super 80 working. He took a photo of it. Had a nice salad lunch. He scanned a number of my documents into his pc. After the sockets are replaced, hopefully some improvement should be noticed, and then I will return to continue the battle. An enjoyable day, I must say!
