Commodore PET assembly line.

This is astonishing - it’s #Elite on the VIC 20! Aleksi Eeben has taken the #Commodore64 source and has ported it to the C64’s predecessor.

It’s looking pretty amazing! Huge kudos to Aleksi, this is a really impressive feat. 🫡

Continuing the day’s dive into old technology, it’s more Beatles, this time an old documentary film on analogue CED Videodisc. With quality barely any better than VHS/Beta (and far inferior to LaserDisc) the format was quitely withdrawn in 1986 after only 5 years on sale.

If you are into anything Amstrad.. This is deffo worth a watch!

Kudos to @morefunmakingit.bsky.social I wish everyone sent stuff packed so well. Cheers Lee!

First time positing about a video on here, and also the first video in what I am hoping will become a new serise. Secret history, a serise all about projects that started off as a secret, and have remained obscure ever since. youtu.be/v7dNorB47Qw

Did you know I have a YouTube channel? And I’m currently doing the history of software in three-letter acronyms? This week, F is for FFT, the fast Fourier transform. Check it out!
