Blue Board is a bulletin board system software created by Martin Sikes (1968–2007) for the Commodore 64 in the 1980s in Vancouver, British Columbia, Canada, and sold worldwide. Due to optimized code and memory allocation , Blue Board boasted very fast performance for a BBS on that hardware platform.

Many microcomputer makes and models could run some version or derivation of the CP/M disk operating system.Eight-bit computers running CP/M 80 were built around an Intel 8080/8085, Zilog Z80, or compatible CPU.
Some single-sided boards which have plated-through holes are made in this way. General Electric made consumer radio sets in the late 1960s using additive boards. The (semi-)additive process is commonly used for multi-layer boards as it facilitates the plating-through of the holes to produce conductive vias in the circuit board.
But IDC’s analysts are also on board, writing: “While A.I.-capable PCs are not ready today, they are coming and have shifted some of the discussion around device purchasing within businesses ...
The Ferguson Big Board The Ferguson Big Board II. The Big Board (1980) and Big Board II (1982) were Z80 based single-board computers designed by Jim Ferguson. They provided a complete CP/M compatible computer system on a single printed circuit board, including CPU, memory, disk drive interface, keyboard and video monitor interface. [1]
Around 1953 to 1959, discrete transistors started being considered sufficiently reliable and economical that they made further vacuum tube computers uncompetitive. Metal–oxide–semiconductor (MOS) large-scale integration (LSI) technology subsequently led to the development of semiconductor memory in the mid-to-late 1960s and then the ...
