Converting an Atari 2600 into a Home Computer; Did That Ever Work?

[Tony] posted an interesting video where he looks at the Atari 2600 and the way many companies tried to convert it into a real home computer. This reminded us of the ColecoVision, which started out as a video game but could expand to a pretty reasonable computer.

It might seem silly to convert a relatively anemic Atari video game into a computer, but keep in mind that computers were pretty expensive in those days. Not to mention, the Atari itself was a fair investment back then, too.

There were four options [Tony] found, although none of them seemed to be very popular. One looked like a cassette player that plugged into your cartridge port and a keyboard port for a cheap-looking keyboard. [Tony] thinks it, along with the “piggy back,” never actually made it to market.

Atari also got into the act with the Graduate. For $79 you got 8K of RAM and a membrane keyboard. There was a big public relations push including a very period TV commercial you can see in the video.

Apparently a dispute between Atari and the actual designers of the Graduate, caused Atari to kill the project with no sales. So far, of the three [Tony] covered, none of them were sold to the public.

The fourth one, CompuMate, was sold for $79. You would get some extra memory and an odd-looking membrane keyboard along with a cassette port. If you want to see the guts, fast forward to 13:30. Like many period computers, it will start up at a BASIC prompt. Unlike many other computers, it would also play Twinkle Twinkle Little Star.

The screen resolution was very poor. Apparently, the flavor of BASIC used by the CompuMate isn’t very well documented. A 100 line program fills up the memory which is funny when you think of how much memory your PC or even your phone has today.

It is hard to realize that the days when this kind of add on might make sense was not that long ago. You can wonder what the computers of 2080 will look like.

If you want to write native, there are ways to do that with a bit of work. There are plenty of ways to get the equivalent of a 2600 — and more — in a much smaller package now.

How To Play Doom – And More – On An NES

Doom was a breakthrough game for its time, and became so popular that now it’s essentially the “Banana For Scale” of hardware hacking. Doom has been ported to countless devices, most of which have enough processing ability to run the game natively. Recently, this lineup of Doom-compatible devices expanded to include the NES even though the system definitely doesn’t have enough capability to run it without special help. And if you want your own Doom NES cartridge, this video will show you how to build it . We featured the original build from [TheRasteri] a while back which goes into details about how it’s possible to run such a resource-intensive game on a comparatively weak system. You just have to enter the cheat code “RASPI”. After all the heavy lifting is done, it’s time to put it into a realistic-looking cartridge. To get everything to fit in the donor cartridge, first the ICs in the cartridge were removed (except the lockout IC) and replaced with custom ROM chips. Some modifica...

Try NopSCADlib for your Next OpenSCAD Project

Most readers of this site are familiar by now with the OpenSCAD 3D modeling software, where you can write code to create 3D models. You may have even used OpenSCAD to output some STL files for your 3D printer. But for years now, [nophead] has been pushing OpenSCAD further than most, creating some complex utility and parts libraries to help with modeling, and a suite of Python scripts that generate printable STLs, laser-ready DXFs, bills of material, and human-readable assembly instructions complete with PNG imagery of exploded-view sub-assemblies. Recently [nophead] tidied all of this OpenSCAD infrastructure up and released it on GitHub as NopSCADlib . You can find out more by browsing through the example projects and README file in the repository, and by reading the announcement blog post on the HydraRaptor blog . Some functionality highlights include: a large parts library full of motors, buttons, smooth rod, et cetera many utility functions to help with chamfers, fillets, precis...

The Newbie’s Guide To JTAG

Do you even snarf? If not, it might be because you haven’t mastered the basics of JTAG and learned how to dump, or snarf, the firmware of an embedded device. This JTAG primer will get you up to snuff on snarfing, and help you build your reverse engineering skills. Whatever your motivation for diving into reverse engineering devices with microcontrollers, JTAG skills are a must, and [Sergio Prado]’s guide will get you going. He starts with a description and brief history of the Joint Test Action Group interface, from its humble beginnings as a PCB testing standard to the de facto standard for testing, debugging, and flashing firmware onto devices. He covers how to locate the JTAG pads – even when they’ve been purposely obfuscated – including the use of brute-force tools like the JTAGulator . Once you’ve got a connection, his tutorial helps you find the firmware in flash memory and snarf it up to a file for inspection, modification, or whatever else you have planned. We always apprec...
