New in revision 1.4:

  1. Circuitry to install 2nd serial port
  2. Circuitry and audio jack to support Processor Technology’s Music System for the Altair (1970’s computer music!)
  3. Expansion port for upcoming internal serial/video interface
  4. And best of all: No need to desolder or otherwise abuse/molest your Arduino Due to use an SD card!

David Hansel has also made some awesome updates to the software that will enable you to upload and save software to the SD card, emulate a 5MB hard drive, support multiple serial ports, and more!

This is a beginner to intermediate kit for people with experience soldering. It can be built in approximately 4-5 hours. Please read the Build Instructions to familiarize yourself with the construction of the kit, and don’t be afraid to email me with questions.

Parts List:

  • 1 x PC Board
  • 36 x 5mm Red LED
  • 36 x 12mm LED Standoff
  • 36 x NPN Transistor
  • 36 x 150Ω Resistor
  • 36 x 10kΩ Resistor
  • 17 x Mini Toggle on-off
  • 8 x Mini Toggle (on)-off-(on)
  • 1 x 470Ω Resistor
  • 1 x 47µF Capacitor
  • 2 x 1kΩ Resistor
  • 2 x 0.1µF Capacitor
  • 1 x Pre-programmed Arduino Due
  • 1 x Front Panel
  • 1 x “Altair 8800” Metalic Sticker
  • 1 x HC-05 Bluetooth Module or MAX3232 DB9 Serial Module
  • 1 x Micro SD Module
  • 1 x DC-022 Power jack
  • 1 x 12v Power Supply
  • 1 x 6 Pin Cable
  • 4 x 14mm Standoff
  • 4 x 20mm Standoff
  • 4 x 3mm Screws
  • 4 x 3mm Nuts
  • 1 x Dual Pin Header
  • 2 x Single Pin Header
  • 1 x 6 Pin Female Header
  • 1 x 3.5mm Audio Jack
  • 1 x USB Cable

Options include:

    • Project box (bamboo, 15″ x 6″) It’s a nice box, but I understand that some people may want to create a more “authentic” case for this project. For this reason, I have made the project box an optional component.
    • You can choose to install an HC-05 Bluetooth module* that will allow you to use a laptop or Bluetooth equipped computer as a terminal, or you can choose to install a MAX3232 DB9 serial connector in order to connect your Altair to a “real” dumb terminal.
    • You can order a kit without the Arduino Due if you (like me) have a bunch of spare Arduinos sitting around from other projects!  (Please note: it must be the Arduino Due, not a Mega or any other model.)

*Please note: due to licensing issues the HC-05 Bluetooth module will not connect to iOS devices (iPhone, iPad, iPod.)

  1. 5 out of 5

    Very easy to build as long as you pay attention to the instructions and advice. Nothing beats the pictures to verify what you’re reading. That was a good tip to install the LEDs last using the panel to align. I suggest the same panel alignment technique with the switches before they are soldered or you will be unsoldering and moving them. I know, I broke one. The PCB design is very clean with minimal jumpers. Definitely fun to take control the computer using switches like the old days.
