Я тут просеивал Интернет по вопросу устройства простых сетевых карт,
и мимоходом наткнулся на весьма симпатичный ретро-компьютер, которого
я ранее не видел:
Dick Smith System 80

The System-80 was powered with a Zilog Z80 microprocessor running at 1.79Mhz and boasted 16K memory on-board. It ran a version of Microsoft Basic which was the same as that in the Tandy Radio Shack TRS-80 model 1 machines. Characters were displayed on the screen 64 wide by 16 deep and graphics mode was the same 128 x 48 grid as the latter. Interfacing was done either through the second cassette port, or a 50-pin expansion bus unique to the System-80. This bus could interface with an optional System-80 expansion unit, offering 32K of extra memory, disk drives, a centronics-compatible parallel printer port and an RS-232.
