It’s been a while since the Spectrum project and, although there is still work left to do on that, I eventually gave in and did another great British computer from my childhood – the BBC B. Getting this machine up and running has been an interesting job given its complexity. For something that first came out in 1981 it really is a sophisticated computer, and one that I’m sure anyone who grew up in the UK in the 80’s and early 90’s will remember.
I’ve written this one up on its own page so that it doesn’t disappear, and the Speccy will get the same treatment in the next few weeks. A bitstream image is provided for you to run on your own DE1 board, if you have one, and the full VHDL source code is available too.
A detailed description of the design is also in the works, and should be ready in a day or two.
