Overview
  • This page amounts to nothing more than a personal collection of data sheets and ideas that I have collected while working towards my Z180 electric wheelchair environment control system, so don't be suprised if you can't follow my reasoning why something has been placed online.

    My eventual aim of this project is to fit a Z180 SBC (Single Board Computer) to my wheelchair. The SBC will be running a copy of CP/M 2.2 and a custom written menu system. The first target is to control my Ericsson T28 mobile phone so I can dial and SMS anyone. This will give me more confidence when I'm out and about on my own.

    Other options that I want to add would be APRS for position reporting, a PS/2 touchpad link from the chair to my desktop PC so I can control it and hence devices in my home without being tied to my desk. FREEDOM!!! :O)
