Description

ZXIO V2 8255A Experimenters Set - DIY Build Kit.

Based on a projectts by ZX81 Keyboard Adventure, the ZXIO V2 is a memory-mapped input/output (I/O) board designed for the ZX81, based around the 8255A-PPI (Programmable Peripheral Interface) IC. This I/O board emphasises simplicity: it is easy to build, easy to connect and interface with, and is accessible from ZX81 BASIC; which is a considerable plus on a ZX81.

 

Package Includes

  • ZXIO V2 PCB and parts: The main component of the kit and brains of the operation.

  • ZX BUS Expander PCB and parts: A ZX81 BUS extension card, the ZXIO or other cards of similar design can be attached to this board.

  • ZX IO LED Board and parts: A unique expansion board designed to be mounted directly to the ZXIO V2 expansion headers.

  • ZXIO Breakout Board and parts: Designed to be used in conjunction with a breadboard for experimentation and prototyping. (Breadboard not included).

  • IDC ribbon Cable.

The kits contain everything needed to build the base ZXIO V2 board, including an LED board and a breakout board. All parts are brand new, with the exception of the 8255A IC, which is a reclaimed component. This decision was made to manage costs effectively; sourcing new versions of this IC would significantly increase the kit cost.

 

***Note*** This is the DIY build kit. You should be confident with building electronics kits. The kit is not suitable for beginners. The completed unit is pictured.
