Collaborate Disseminate
We know that a lot of our beloved readers don’t take kindly to abuse of vintage hardware, so the Atari fans in the audience may want to avert their eyes for this one. Especially if they’re particularly keen on spinning up their Jawbreaker cassette on authentic hardware, as [iot4c] has …read more
If you listened to the National Weather Service Weather Radio in the US about 25 years ago, you’ll no doubt remember [Perfect Paul], one of the synthesized voices used to read current conditions and weather forecasts. The voice came from a DECtalk DTC01, a not inexpensive voice synthesizer first made …read more

Imagine you’re time-warped back to 1979 and tasked with constructing a personal computer. Could you do it? [RadicalBrad] thinks he can, and his 6502-based “Super VIC” build looks like it’s off to a great retrocomputing start.
Most emulations of old hardware these days go the FPGA route, and while we …read more

A ruler seems like a pretty simple device; just a nice straight piece of material with some marks on it. There are some improvements out there to the basic design, like making it out of something flexible or printing a few useful crib notes and formulas on it so you …read more

We’ll forgive you if you were busy in the ’80s, and missed the TRS80 Model 100. It was a portable version of the original, ran on four AA batteries, and even had an integrated acoustic coupler which proved handy for workers on the go. However, time is rarely kind, and [Trammell] had come across a non-functional example for just $20. It was time to bring this relic screaming into the modern age.
The motherboard was toast, so [Trammell] decided to wire up a Teensy++ directly to the Hitachi HD44102 display driver chips. Being an older LCD, the display needed a …read more

Hackaday Superconference is just a week away (precious few tickets remain), a celebration of all things Hackaday, which naturally includes creative projects making the most of their hardware. Every attendee gets a platform for hacking in the form of the conference badge.
To make the most of your badge hacking fun, plan ahead so you will have the extra components and the tools you need. At the most basic, bring along a serial to USB cable and a PIC programmer. These are common and if you don’t own them, ask around and you will likely be able to borrow …read more

It hangs around your neck, comes with the cost of admission, and would blow away a desktop computer from the 1980’s. This is the Hackaday Superconference badge and you can get your hands on one for the price of admission to the ultimate hardware conference.
Everyone through the door gets one of these badges featuring a 320 x 240 color display, a full qwerty keyboard, and limitless hacking potential! The stock firmware runs a BASIC interpreter, the CP/M operating system, and includes games and Easter Eggs. It’s a giant playground, and we want to see what you can do with …read more
If you were lucky enough to own one of the crop of 1980s 8-bit computers, did you ever pause to consider how its graphics worked? Maybe the really expensive ones had dedicated CRT controller subsystems akin to the graphics cards you’d have found on a PC a few years later, but most of the affordable models would have stopped what they were doing every TV line interval period to allow access to their memory for their graphical output to be created.
The RC2014 retrocomputer dodges all this, by using a serial port as an interface and expecting your serial terminal …read more

One of the outliers in the home computer wars of the early 1980s was the Texas Instruments TI99/4A. It may not have had the games library of its rivals and its TMS9900 processor may not have set the world on fire with its registers-in-RAM architecture, but its range of support chips included one whose derivatives would go on to delight subsequent generations. If you had an MSX or one of the 8 or 16-bit Sega consoles, the TMS9918A graphics chip provided the architecture that sat behind Sonic in his adventures.
A few decades later, there is still significant interest in …read more

Fun fact, the Osborne 1 debuted with a price tag equivalent to about $5,000 in today’s value. With a gigantic 9″ screen and twin floppy drives (for making mix tapes, right?) the real miracle of the machine was its portability, something unheard of at the time. The retrocomputing trend is to lovingly and carefully restore these old machines to their former glory, regardless of how clunky or underpowered they are by modern standards. But sometimes they can’t be saved yet it’s still possible to gut and rebuild the machine with modern hardware, like with this Raspberry Pi used to revive …read more
