The next, project was to house the NeoClassic system. This required the design of a backplane (#06) which fitted in the housing. It has become a self contained computer with internal power supply (an old iPhone USB charger), with keyboard and video connections thanks to the Raspberry Pi Zero Serial Terminal.

BlueBox2

Description

  • Runs CP/M
  • Powered by the USB cable
  • Communication via terminal (USB-FTDI)
  • The CF card is accessible from the rear

In this project I used a smaller enclosure.
W=17cm D=13cm H=9cm (6.7" x 5.1" x 3.1")
Fitting the kit into the case was straight forward using the following parts:
  • BackPlane 5C - 5 slots RC80 bus
  • 10c - Storage module, rear connection
  • 21d - Z80 cpu , 7.3Mhz
  • 45d - Memory module 64kb RAM (SC monitor)
  • 33e - Serial terminal MC68B50P ACIA + CLK
