Articles About Building FPGABee
These articles give a detailed look at what was involved in building FPGABee...
A series of articles describing the build of FPGABee version 1 with functionality roughly equivalent to a ROM based PC85 model.
These articles cover building of FPGABee version 2 which took a new approach and resulted in functionality equivalent to a HDD based Premium 128K Microbee.
Looks at packaging FPGABee into a small plastic case, with a custom PCB using a tiny Xula FPGA board.
