What is it?

This is a small digital video adapter that plugs into the video port on the back of the Apple IIc or Apple IIc+, and now supports the Laser 128 as well. It runs Mike Neil's A2CDVI firmware which the RP2040 microcontroller uses to convert the various video signals to reconstruct the video output in TDMS format. It outputs video to a monitor using the DVI format via an HDMI connector and supports 720x480p or 640x480p resolution.

Now shipping version 2.5 that supports all of the features in v1.8.3 of Mike’s firmware, and expands compatibility to HDTVs in addition to monitors.Why did you make it?

I made it because Mike's adapter board schematic for the A2DVI card works but it is really big and great for tinkering but not a good portable solution. This makes it very small and eliminates the extra unused chips from the A2DVI.

What makes it special?

This is a new and very inexpensive open source solution to output video from the Apple IIc and IIc+ to modern monitors. This design is open source itself and open hardware.

What do I get with this order?

You will receive a completed, flashed and tested board, installed in a 3D printed case and shipped in an antistatic bag. I hand test each board in my Apple IIc before shipping.
