It's inspired by Simon Tatham's classic puzzle collection, nice!
A similar type of puzzle I made in the past: https://www.quaxio.com/sliding_puzzle/puzzle.html

Prior art (I'm sure there are earlier ones):
https://www.quaxio.com/pure_css_digital_clock.html
CSS only digital clock "best viewed at noon or midnight". Discussed at https://news.ycombinator.com/item?id=25595439
Of course this one is no different and can't tell the current time.

I had a Cromemco Dazzler (still have it). Nifty graphics board for the S-100 bus. Uses DMA off system memory. Here are some links to further info. (PDF's)

Yes, they are copyrighted. The link to article points to this equivalent, free ECMA 119 standard: https://www.quaxio.com/files/2018/bootable_cd_retro_game_tweet/ecma-11…

I am 99% that's not the case. The author has a public profile my guess is that he is referring to this[1].
