As computers age, a dedicated few work towards keeping some of the more interesting ones running. This is often a losing battle of sorts, as the relentless march of time comes for us all, human and machine alike. So as fewer and fewer of these machines remain new methods are needed to keep them running […]
IBM mainframes are known for very unusual terminals. But IBM made many different things, including the IBM 3151 ASCII terminal, which uses a cartridge to emulate a VT220 terminal. [Norbert Keher] has one and explains in great detail how to connect it to a mainframe. It had the 3151 personality cartridge for emulating multiple IBM […]
Even if you aren’t a Disney fan, you probably know about EPCOT — Experimental Prototype Community of Tomorrow — a Disney attraction that promised a glimpse of the future. [ErnieTech] takes a glimpse at the UNIVAC computer that ran the operation in the 1980s. A lot of schools had UNIVAC 1100-series computers back in those […]
Should you travel around Europe, you may notice that things in France are ever so slightly different. Not necessarily better or worse, simply that the French prefer to plough their own furrow rather than importing cultural tends from their neighbors. In the 1980s this was evident in their home computers, because as well as a […]
There’s a dedicated group of users out there that aren’t ready to let their beloved IBM PC110 go to that Great Big Data Center in the Sky. Unfortunately, between the limited available technical information and rarity of replacement parts, repairing the diminutive palmtops can be tricky. Which is why [Ahmad Byagowi] has started a project […]
If Clive Sinclair’s genius in consumer electronics was in using ingenious hacks to make cheaper parts do greater things, then his Amstrad competitor Alan Sugar’s was in selling decade-old technology to consumers as new and exciting. His PCW series of computers are a great example, 1970s CP/M machines smartly marketed for late 1980s home offices. […]
It’s been 30 years since Windows 95 launched. [Ms-Dos5] and [Commodore Z] are celebrating with an epic exhibit at VCF East 2025. They had no fewer than nine computers — all period-correct machines running versions of Windows 95. The pictures don’t do it justice, so if you are near Wall, NJ, on Sunday, April 5, […]
[Ben Eater]’s breadboard 6502 computer is no stranger to these parts, so it was a bit of a surprise that when [Mark] wrote in asking us if we’d covered [Ben]’s getting MS BASIC running on the breadboard, that our answer was “no”. Well, that changes today! This is a three-part video series, documenting how [Ben […]
Usually when we talk about retrocomputing, we want to look at — and in — some old hardware. But [Z→Z] has a different approach: dissecting MacPaint, the Apple drawing program from the 1980s. While the program looks antiquated by today’s standards, it was pretty hot stuff back in the day. Things we take for granted […]
We remember when the transputer first appeared. Everyone “knew” that it was going to take over everything. Of course, it didn’t. But [Oscar Toledo G.] gives us a taste of what life could have been like with a JavaScript emulator for the transputer, you can try in your browser. If you don’t recall, the transputer […]
