Gary's Digital Basement - HDMI for the Apple ][

 See https://www.8bitdevices.com/ It uses a Raspberry Pi Pico and he thinks you don't even need the TTL Level shifters to produce HDMI output.

If someone reading this has a Facebook account, please write a link to this post onto his FB page.

This was in The Guardian: David Turner obituary , only eight days after I posted  David Turner Talking About Sixty Years of Functional Programming History : This talk was given in London in 2017: See  Turner, D. A. "Some History of Functional Programming Languages" also  John Hughes - Why Functional Programming Matters  and David MacQueen's talk at ICFP 2015 in  Numberphile - Sophie Maclean on the Catalan Numbers .
