The Amiga Love Twitter feed posts about this Raspberry Pi Zero-based video card for vintage Amiga computers with video slots (above in an Amiga 2000).

The information links to this recent GitHub repo by user Bloodmosher. A software image for the Pi Zero is included.
The project above builds on the c0pperdragon Amiga-Digital-Video project which uses a Pi Zero to add HDMI video to Amiga 500 machines (below).

These are fabulous developments!
Ed. note: If anyone knows of a HDMI out emulating an 8 bit IBM PC VGA card, please drop me a note on Twitter at @anne_engineer. // Read more: original article.
