Nothing lasts forever, and that includes the ROMs required to make a retrocomputer run. Even worse, what if you’re rolling your own firmware? Period-appropriate EPROMs and their programmers aren’t always cheap or easy to get a hold of these days. [Kyo-ta04] had that problem, and thanks to them, we now all have a solution: Pico2ROMEmu, […]
Over on YouTube [Usagi Electric] shows us how to make RAM for the TMS9900. He starts by remarking that the TI-99/4A computer is an excellent place to start if you’re interested in getting into retro-computing. Particularly there are a lot of great resources online, including arcadeshopper.com and the AtariAge forums. The CPU in the TI-99 […]
Although largely recognizable to anyone who had a video game console in the 80s or 90s, cartridges have long since disappeared from the computing world. These squares of plastic with a few ROM modules were a major route to get software for a time, not only for consoles but for PCs as well. Perhaps most […]
Like the rest of us, 8-bit hardware is not getting any newer, and failed ROMs are just a fact of life. Of course you can’t call up Commadore corporation for replacement parts anymore, so something is needed. [Peirs Rocks] wasn’t satisfied with the existing options, so he came up with the Software Defined Retro ROM […]
The Apple Macintosh Plus was one of the most long-lived Apple computers and saw three revisions of its 128 kB-sized ROMs during its life time, at least officially. There’s a fourth ROM, sized 256 kB, that merges the Western ROMs with Japanese fonts. This would save a user of a Western MacIntosh Plus precious start-up […]
With today’s technology, emulating video game consoles from the 90s or before is trivial. A Raspberry Pi and a controller of some sort is perhaps the easiest and simplest way to go to get this job done, but to really impress the masses some extra effort is required. This handheld from [Eli] called the Game […]
As we all know, when developing software for any platform or simply hacking a bit of code to probe how something works, the ability to deploy code rapidly is a huge help. [Martin Donlon], aka [wickerwaka], is well known in retro gaming and arcade hardware reverse engineering circles and had the usual issues figuring out […]
We’ve seen a few retro products using core rope memory, such as telephone autodiallers. Obviously, we’ve covered the Apollo program computers, but we don’t think we’ve seen a complete and functional DIY computer using core rope memory for program storage until now. [P-lab] presents their take on the technology using it to store the program […]
We’ll all be familiar with Tic-Tac-Toe, or Noughts and Crosses, a childhood pencil-and-paper diversion which has formed the basis of many a coding exercise. It’s an easy enough task to implement in software, but how many of us have seen it done in hardware alone? That’s just what [Warren Toomey] has done using TTL chips, […]
Maybe you’ve heard of a TV show called The Simpsons. Steamed Hams make a one-gag appearance in an unforgettable luncheon where Principal Skinner poker-faces his way out of a disaster with Superintendent Chalmers. Meanwhile, over on imgur, [Agumander] has put a black and white screencap from Steamed Hams in a printed circuit board. The memory […]
