Acrylic case and I/O expansion upgrade


Due to Chinese New Year and Coronavirus, some of my parts shipments have been delayed! I should have kits available by the end of February. 🙁 Check back.

Out of stock



This kit will upgrade your version 1.4 kit (with bamboo case – purchased between Jan 2018 and July 2019) to the new blue and gray acrylic case with I/O expansion card. For installation instructions, see this page.

Kit includes bolt-together acrylic case and I/O expansion circuit board with necessary components.  Also included is the new spiral-bound instruction and operation manual.

This upgrade is designed for version 1.4 of the Altair-Duino kit (with connectors for expansion board.)

Please note: installing the I/O expansion will require the removal of your Bluetooth module.  If you use (and want to continue using) your Bluetooth module, you can do that by *not* installing the PIC32 IC.  However, this will mean your VT100 emulator will not work. There is another, more labor intensive method of keeping both Bluetooth and the VT100 emulator detailed in the upgrade instructions.

This upgrade includes desoldering components, cutting a circuit board trace, and modifying a connector. Please read the upgrade instructions and determine if this is a project you want to undertake.
