BBC is the short name for the Acorn BBC Micro, which was very popular in the mid-to-late 80s. There were several versions of this computer but the one that has been revived in this project is the BBC B.
The core of this device was the famous 6502 processor. This article thoroughly defines each part of the BBC B and its current status on the FPGA. Some of the parts have not been implemented, either for physical restrictions or not real need for them. So, another challenge for you to build a complete BBC B with you FPGA.
A PAL TV was used as the author did not try to add a scan-doubler for the video output. But don´t worry. Everything is very well explained. Plus, there is a Design Detail page that guides you step-by-step through the implementation process.
The source code has been written on VHDL (given). Also the ROMs info is provided as well as some known bugs so you can avoid them beforehand.
So now, what is stopping you from playing again “Pole Position” or “Boffin”???
It couldn´t be easier! Have fun!
