Vintage BBC Computer gets FPGA Buddies

? The BBC Microcomputer System (or BBC Micro) was an innovative machine back in the early 1980?s. One feature that impressed reviewers was a ?tube? interface that allowed the machine to become an I/O processor for an additional CPU. When the onboard 6502 became too slow, it could become a slave to a Z-80 or even an ARM processor. The bus was actually useful for any high-speed device, but its purpose was to add new processors, a feature Byte magazine called ?innovative.? [Hoglet67] has released a very interesting set of FPGA designs that allows a small board sporting a Xilinx Spartan 3 to add a 6502, a Z80, a 6809, or a PDP/11 to a BBC Micro via the tube interface. There?s something satisfying about a classic computer acting as an I/O slave to a fairly modern FPGA that implements an even older PDP/11. ? http://hackaday.com/2015/10/03/vintage-bbc-computer-gets-fpga-buddies/ -- Liam Proven ?
