SC512, v1.0, Description

SC512 is a prototyping breakout card designed for Z50Bus.

This has been designed primarily as an aid to prototyping Z50Bus cards with solderless breadboards, although it does also include a prototyping area.

Z50Bus signals to be easily connected to a breadboard with Dupont cables.

The board includes flexible I/O address decoding, so you don’t need to include such circuitry on every prototype. The decoding has jumpers to configure the start address and range. This includes allowing partial decoding with shadow addresses.

The address decoding circuit provides an I/O enable signal (/IOEN) and also separate read and write versions (/IORD and /IOWR). This range of enable signals allows easy interfacing to most I/O devices.

The main features of this card are:

  • Easy access to Z50Bus signals
  • Flexible address decoding generates /IOWR, /IORD and /IOEN
  • Connection to solderless breadboards with Dupont cables
