Collaborate Disseminate
Join us Wednesday at noon Pacific time for the Home Machine Shop Hack Chat!
Even if you haven’t been here for very long, you’ll probably recognize Quinn Dunki as Hackaday’s resident consulting machinist. Quinn recently did a great series of articles on the “King of Machine Tools”, the lathe, covering …read more

One of the better retro historians out there on YouTube is the 8-Bit Guy, and after years of wanting to do something like this, it’s finally happening. The 8-Bit Guy is building his dream computer, heavily inspired by the Commodore 64.
Before we go into what this computer will do …read more
Arduinos are a handy tool to have around. They’re versatile, cheap, easy to program, and have a ton of software libraries to build on. They’ve only been around for about a decade and a half though, so if you were living in 1989 and wanted to program a microcontroller you’d probably be stuck with an 8-bit microprocessor with no built-in peripherals to help, reading from a physical book about registers and timing, and probably trying to get a broken ribbon cable to behave so it would actually power up. If you want a less frustrating alternate history to live in, …read more
Why would anyone bother to create new content for a console system that’s staring down its 40th birthday? Perhaps just for the challenge of fitting a game into 40 kilobytes of storage.
That at least seems to be the motivation behind [Morphcat Games] pending release of Micro Mages, a new game for the Nintendo Entertainment System console that takes its inspiration from Super Mario Bros. The interesting bit here is how they managed to stuff so much content into so little space. The video below goes into great detail on that, and it’s a fascinating lesson in optimization. …read more

[Kenneth Wilke] is undertaking a noble quest – to build a homebrew microcomputer, based around the venerable 6502. As a prelude to this, he set out to interface the hallowed CPU to an FPGA, and shared the process involved.
[Kenneth] is using an Arty A7 FPGA development board which is a great fit for purpose, having plenty of I/O pins and being relatively easy to work with for the home tinkerer. This is an important consideration, as many industrial strength FPGAs require software licences to use which can easily stretch into the tens of thousands of dollars.
The 6502 is …read more

If you always wished you could get closer to the hardware with the 6502 in your classic microcomputer you’re in luck, because [Drass] has created a beautiful implementation of a 6502 using TTL logic chips. What makes it special is that it sits on a very neat set of PCBs, and due to its use of 74AC series logic it can run at much higher speeds than the original. A 20 MHz 6502 would have been revolutionary in the mid-1970s.
Through a flying ribbon cable, it can plug directly into the 6502 socket on classic microcomputers, and the website shows …read more

All the retrocomputer love for Commodore machines seems to fall on the C64 and Amiga, with a little sprinkling left over for the VIC-20. Those machines were truly wonderful, but what about the Commodore machine that paved their way? What about the machine that was one of the first to be gobbled up in the late 1970s by school districts eager to convert a broom closet into the new “computer lab”?
The PET 2001 might be a little hard to fall in love with given its all-in-one monitor, cassette recorder, and horrible chiclet keyboard, but some still hold a torch …read more

Some electronics gear is built for the roughest conditions. With rugged steel cases, weatherproof gaskets, and cables passing through sealed glands, these machines are built to take the worst that Mother Nature can throw at them, shrugging off dust, mud, rain, and ice. Consumer-grade computers from the start of the home PC era, however, are decidedly not such machines.
Built to a price point and liable to succumb to a spilled Mountain Dew, few machines from that era that received any kind of abuse lived to tell the tale. Not so this plucky Commodore 64C, which survived decades exposed to …read more

Falling into the marvelous space between, ‘I really want to do that’ and ‘but that’s a lot of work and I’m lazy’ comes this reproduction of the motherboard from the original IBM 5150. This is a complete reproduction of the first PC, being sold as a kit. Yes, chips are included, although I highly doubt they’ve gone through the trouble of finding chips with contemporaneous date codes. We’re dying for a writeup on this one.
Someone has found the source code for the first Furby. [Mark Boldyrev] was talking with a few fellows on the MAME forum to see if …read more
