BBC B Tweeting Machine
My BBC B running serial terminal software called Termulator, connected to my Linux desktop which is running the text only web browser Lynx to use Twitter. The terminal software is fairly temperamental, certain codes seem to make everything freeze up. Also, it’s hard to find 5 pin DIN plugs with the right pin configuration these days.

This was my first computer. It was in constant use from 1986 until 1994. I learned to program on it.
