I would like to point out something very serious. Years ago I developed a technique for shifting serial data into a 74hc595 chain without use of a microcontroller. I have not been able to help but notice that people have been using raspberry pi's instead of my simple circuit.
For the same reason you DONT actually need 32G of ram to run a web browser, you don't need to use a Pi to convert serial data to parallel. I mean cmon, Its using a 555 as a BUFFER. a BUFFER!

Your 1990s files are slowly turning into magnetic dust. Leontien Talboom at Cambridge University Library is leading a rescue mission for our digital past. She uses hobbyist tools to pull data from moldy disks that standard drives can't touch. She even recovered lost lectures by Stephen Hawking. You can use her Copy That Floppy! guide to save your own archives. It requires specialized hardware like the Greaseweazle to capture raw magnetic pulses. Don't wait until the iron oxide flakes off for good. Check your storage boxes for those chunky rectangles before they become silent plastic.

The archivist preserving decaying floppy disks

It's a race against time (and magnetic decay) to preserve decades of cultural history stored on obsolete hardware.

Born #onthisday in 1799, the English botanist Anna Atkins. As well as being considered by many to be first woman to create a photograph, her stunning 1843 book of algae cyanotypes is thought to be first book illustrated with photographs: https://publicdomainreview.org/collection/cyanotypes-of-british-algae-by-anna-atkins-1843?utm_content=buffer43f58&utm_medium=social&utm_source=facebook.com&utm_campaign=buffer #OTD

What explains the popularity of terminals with 80×24 and 80×25 displays? A recent blog post " 80x25 " motivated me to investigate this. The ...

The Underwood Multi-tool (c. 1850)

Decades before the first Swiss Army knife (1891), London’s Underwood of Haymarket crafted this "harped" pocket kit. Designed for Victorian sportsmen, it features a hoof pick, saw, and corkscrew. A rare 19th-century masterpiece of portability.
