Developer Salvatore Sanfilippo, known as antirez and the creator of Redis, has released a Commodore 64 hardware simulator on GitHub. The tool models the machine's circuitry at a level where users can deliberately break chips or individual pins and observe the effects on the system. It is drawing attention from retrocomputing and electronics enthusiasts curious about low-level hardware behaviour.

A hobbyist has built a fully functional 16-bit magnetic core memory unit as a DIY project, demonstrating a working version of the storage technology that predated modern silicon RAM. The build showcases hand-wound core arrays that can store and read 16 bits of data, drawing interest from electronics and retrocomputing enthusiasts who admire the rare hands-on revival of 1950s-era computing hardware.

A regular programming show has resumed its usual schedule, with the latest episode featuring Jeff Shrager, Kent Pitman and Ramin Honary on air, plus audience participation in a MOO virtual reality space. The discussion covered Lisp, 3-Lisp and retrocomputing topics, with the host praising the episode as great.

A retrocomputing enthusiast spent a refurbishment weekend bringing an Alpha Micro Eagle 300 back to working order, documenting the process alongside other vintage machines. The write-up covers troubleshooting and repair of the 1980s multiuser microcomputer, drawing attention from classic computing fans who enjoy restoration projects and the preservation of early multiuser systems.

A retrocomputing enthusiast is on the hunt for a good deal on an SVGA CRT monitor, tying the search to a bit of detective work with classic games like Where in the World Is Carmen Sandiego? running on DOS-era Pentium hardware. The post, tagged with retrocomputing and retrogaming hashtags, playfully asks readers not to judge the nostalgic pursuit.
