I've spent quite a bit of time playing with, looking after, taking to bits and reassembling (particularly reassembling) Acorn A4 laptops. Hopefully the following information should be of use to others working with them.

  • Dismantling the A4 base as far as the motherboard
  • Removing the screen and replacing the LCD panel
  • LCD panel data
  • Using the A4 LCD panel on an A7000 board
  • The Triumph Alder Walkstation: a PC in an A4 case.
  • Motherboard pictures
  • The keyboard membrane
  • DIY Ethernet card
  • Common faults
  • 'Frequently' asked questions
  • Offsite: Technical Reference Manual
  • Offsite: Circuit diagrams
  • Occasional A4 blog
