Lundy Electronics SuperADAM 2026-1 build log

[Tekman]

I’m sharing the first SuperADAM build of 2026 here for everyone to see the process of what goes into building a Lundy Electronics SuperADAM console.

The first three consoles in this batch will have the rarer dark beige bottoms and will include a free I/O Expansion Hub. All consoles come with a professionally printed metalized vinyl decal on the front panel for branding and showing a Lundy Electronics authentic SuperADAM.

Building up the case and external DDD assembly

Installing boards. All hardware and metal RF tins get polished to a nice shine. This example already had some good looking RF tins and probably one of the best I've ever seen.

I wasn't happy with the final internal cable harness length for the external data drive and had to order more wire to make a little longer one. I'm in a holding pattern until then.

Everything is so clean and shiny! and I'm sure minty fresh.

I saw your Facebook post. My vote would definitely be to wait for HDMI!

[Tekman]

After getting sidetracked for a few days, the PICO9918 is now installed. The default VGA dongle looks great, but that will be swapped for HDMI once the new HDMI dongles get here.
