Before you can do anything (other than watch the blinkenlights) you’ll need to connect your Altair 8800 to your computer via USB.
Requirements:Terminal software (Putty is highly recommended.)
- Plug USB cable into computer (the other end should already be connected to the programming port on the Arduino.)
- Windows 10 should automatically recognize a new serial port. To check , launch “Device Manager”.
- Expand “Ports (COM & LPT)” in Device Manager
- Your port should be identified as “Arduino Due Programming Port”.
- Launch PuTTY (or another terminal program if you choose.)
- Connect to the indicated COM port at baud rate 115200.
- The front panel lights will flash briefly while it connects.
- With all switches down, press AUX1 down.
- On the terminal, you should see a directory of options for front panel switches.
Now that you’re connected to the Altair-Duino, I’d suggest setting it up so you can Easily Switch Between Serial Devices.
