Tandy 1000 EX/HX 3-in-1 Upgrade


This is a drop-in upgrade for either the Tandy 1000 EX or Tandy 1000 HX. The 3-in-1 provides your computer with:

  • Fully expanded system memory - 640Kb conventional + 96Kb UMB
  • Standard DB9 RS232 Serial Port
  • XT-IDE ‘CF Lite’ Interface


This is a new adapter made by me, based on the‘Tandy-EX-HX-3in1’project originally created by the user ‘rkrenicki’,Rob Krenicki. His project can be found on GitHub and Tindie. The only difference between his version and mine is that I have remixed the mounting plate to include mounting hardware and I also include a pre-formatted CF card.


This package includes:

  • Assembled and tested PCB
  • Formatted and bootable compact flash card
  • Mounting hardware
  • Ships USPS from Wisconsin, USA.


    I'm committed to providing excellent service, so if you have any questions, please do not hesitate to contact me.


    Thanks for looking!
