The Bellmac-32 CPU — What? - If you have never heard of the Bellmac-32, you aren’t alone. But it is a good bet ... - https://hackaday.com/2025/06/06/the-bellmac-32-cpu-what/ #retrocomputing #bellmac-32 #belllabs #att
Has anyone out there made #retrocomputing a business or career?
I am inept where it comes to finding someone to take over my #Commodore collection. It is a total mess right now as I can't easily sort it all out. I don't speak German to the point where I feel confident joining the German forums. If I can't find a new owner for these things, it'll mean a rough thousand tapes, floppies, and A500 diskettes with various software will bitrot away, caps and batteries will deteriorate, and I might as well trash it all. Help? #Help #commodore64 #retrocomputing
Codebase 64 just disappeared! 
#FujiNet is a WiFi Adapter for #retrocomputing and #retrogaming systems. It speaks JSON, XML, and HTTPS, so it can talk to any Internet endpoint, directly.
We use it for FujiNet 5 Card Stud, so this DOS based IBM #PCjr has no problem speaking JSON. :)

En 1990, Olivetti sort le PCS286 : un PC équipé d’un processeur de 1982, 1 Mo de RAM, 20 Mo de disque dur, et un écran CRT monochrome façon centrale nucléaire. Tardif, poussif, mais farouchement européen. Le baroud d’honneur du rétro avant l’heure.

Single-Board Z80 Computer draws Inspiration from Picasso.
Picasso and the Z80 CPU are not two things we often think about at the same time. One is a renowned artist born in the 19th century, the other, a popular CPU that helped launch the microcomputer movement. And yet, the latter has come to inspire a computer based on the former.

The RC2014 Mini II, it’s a single-board Z80 retrocomputer that you can use to do fun things like run BASIC, Forth or CP/M.
However, where it gets kind of fun is in the layout. It’s the same fundamental circuitry as the RC2014, but it’s been given a rather artistic flair. The ICs are twisted this way and that, as are the passive components [even some of the resistors are dancing all over the top of one another].
The kit is a limited edition, too, with each coming with a unique combination of colors where the silkscreen and sockets and LED are concerned. Kits are available via Z80Kits for those interested.

There are so many good online -and free- resources for #retrocomputing #programming for the #c64 #8bit ( @internetarchive says archive is offline so didn't post those links to like resources):

#retrocomputing experiment
I set up a #RaspberryPi to run like an old Unix terminal, writing documents in #troff
Everything went well until I needed to view a PDF document. I found a program that can use the frame buffer to display images and PDFs. Works great!
You can do modern things at the console, you just need to use different tools to get there. 
Here's my article:

Ok so a standard circuit board is 1.57 mm or 0.062 inch thick, and a S100 circuit board is 5 inch x 10 inch.
So I've ordered some 8" x 12" plastic sheets that are 1.5 mm thick, and a pair of 80mm 12v fans to build a fan card to help cool my S100 CP/M box!
Gierig gewesen und fast den Preis bezahlt: Der SID saß sehr stramm im Sockel des #Commodore64, ich musste etwas stärker daran herumhebeln, nur mit Schraubendreher zur Hand.
Resultat: Chip draußen, aber einige Beinchen verbogen. Ließen sich mit etwas Fingerspitzengefühl wieder richten, aber viel hat nicht gefehlt, dann hätte ich sie sicher abgerissen.
Die Moral von der Geschicht': Verzichte auf's richtige Werkzeug nicht! Und lass dir Zeit, verdammt.
@8bitboyz I think we’ve matured and no longer engage in that kind of playground mentality. As #retrocomputing enthusiasts, I think most people can appreciate every system for what they are. A Commodore kid myself, I also have Spectrums and a couple of TI’s now, and enjoy playing with other systems on MiSTer. They are all lovely with their own quirks and strengths, but it’s okay that one system holds a special place in your heart.
I worked at a computer store in Toronto in 1983. Due to the power-surge tape erasure issue, plus the printer/power supply design flaw, we had a near 100% return rate on the Adam.
Pretty sure the only reason Coleco didn't go bankrupt in 1983 was because they introduced Cabbage Patch Kids the previous year.
42 years ago today, Coleco unveiled its ill-fated Adam computer. It was a good value for the money but they couldn't build it in sufficient quantities and quality control issues ran rampant. It only lasted 24 months on the market. #retrocomputing https://dfarq.homeip.net/coleco-adam-computer/
In 1978, Prof. Verbaeten ported 7th Ed. Unix to the Motorola 68000 at KU Leuven in Belgium. This port is not archived at TUHS, only mentioned here:
https://eng.kuleuven.be/en/stories/50-years-of-computer-science-engineering
https://museum.cs.kuleuven.be/misc/Tim_Ameye_Sander_Van_Loock_40-jaar.pdf (p. 12)
There's also a paper describing the port which is not available:
Verbaeten, P., Berbers, Y. (1983). Porting Unix. In: Proceedings of UNICOM Conference, San Diego.
If you happen to have pointers to any of this, I would be happy to hear from you!
On just about every modern operating system, the type of a file is determined primarily by the ending of its name.
Madness.
#Macintosh #MacOS got it right the first time.
