BBC MICRO MODEL B RESTORATION SERIES PART 2: Memory and Video sync repairs.
Welcome to part 2 of a three part series I have recorded about the BBC Micro, including some of the repairs it will need through out its life.
In this video I will replace a faulty memory IC and also replace a faulty Logic IC for the RGB video output.
I have chaptered this video, so that you can go straight to the part you are interested in.
Unfortunately I did have a slight mishap with using a hot air gun on the RGB IC removal, but in the end everything worked out well.
