Resurrecting An Amiga CD32

As an editor on Amiga magazines in a previous life, this is kind of bittersweet. [RetroManCave] was donated an Amiga CD32 games system, and it is trying to resurrect it. If you’ve not heard of it, the CD32 was a 1993 games console based on the Amiga home computer system. It was the last gasp for Commodore, the beleaguered company behind the Amiga. In this first video of a series, they take the system apart, take you through what’s inside and boot it up. The system boots, but there is some sort of problem with the video sync, and they …read more

Printed PC Speakers Are Way Cooler Than Yours

On the off chance you’re reading these words on an actual desktop computer (rather than a phone, tablet, smart mirror, game console…), stop and look at the speakers you have on either side of your monitor. Are you back now? OK, now look at the PC speakers and amplifier [Chris Slyka] recently built and realize you’ve been bested. Don’t feel bad, he’s got us beat as well.

The speaker and amplifier enclosures were painstakingly printed and assembled over the course of three months, and each piece was designed to be small enough to fit onto the roughly 4 in x …read more

Old TV Lends Case to Retro Magic Mirror

Remember the days when the television was the most important appliance in the house? On at dawn for the morning news and weather, and off when Johnny Carson said goodnight, it was the indispensable portal to the larger world. Broadcast TV may have relinquished its hold on the public mind in favor of smartphones, but an information portal built into an old TV might take you back to the old days.

It seems like [MisterM] has a little bit of a thing for the retro look. Witness the wallpaper in the video after the break for proof, as well as …read more

Raspberry Pi Compute Module 3 in a GameBoy Original

[Kite] has been making custom PCBs for GameBoys for a long time. Long enough, in fact, that other people have used his work to build even more feature-rich GameBoy platforms. Unfortunately some of their work had stagnated, so [Kite] picked it up and completed a new project: a GameBoy that uses a Raspberry Pi running on his upgraded GameBoy PCB.

At its core the build uses a Raspberry Pi 3, but one that has been shrunk down to the shape of a memory module, known as the Compute Module 3. (We featured the original build by [inches] before, but [Kite] …read more

Why Only Use One Controller When You Can Use ALL Of Them?

After booting up his RetroPie system, [jfrmilner] had the distinct feeling that something was off. Realizing that the modern Xbox 360 controller didn’t fit right when reliving the games of his youth, he rounded up all his old controllers to make sure he always had the right gamepad for the game.

Wanting to keep the controllers unmodified — so they could still be used on the original systems — he had to do a bit of reverse-engineering and source some controller sockets before building his controller hub. Using shift-in registers, shift-out registers, and some multiplexers, he designed a large circuit …read more

An Old Video Game Controller on Even Older Computer

For those of us not old enough to remember, and also probably living in the States, there was a relatively obscure computer built by Microsoft in the early 80s that had the strong Commodore/Atari vibe of computers that were produced before PCs took over. It was known as the MSX and only saw limited release in the US, although was popular in Japan and elsewhere. If you happen to have one of these and you’d like to play some video games on it, though, there’s now a driver (of sorts) for SNES controllers.

While the usefulness of this hack for …read more

The 1980s called – asking for the Z80 Membership Card

The ’80’s and early ’90’s saw a huge proliferation of “personal” computers, spawning an army of hacker kids who would go on to hone their computing chops on 8-bit and 16-bit computers from brands such as Sinclair, Commodore, Acorn, Apple, Atari, Tandy/RadioShack and Texas Instruments. Fast forward to 2017, and Raspberry-Pi, BeagleBone and micro:bit computers reign supreme. But the old 8-bit and 16-bit computer systems can still teach us a lot.

[Lee Hart] has built the amazing Z80 Membership Card — a Z80 computer that fits in an Altoids tin. His design uses generic through hole parts mounted on a …read more

3D printed Math Grenade

Calculator hacks are fun and educational and an awesome way to show-off how 1337 your skills are. [Marcus Wu] is a maker who likes 3D printing and his Jumbo Curta Mechanical Calculator is a project from a different era. For those who are unfamiliar with the Curta, it is a mechanical calculator that was the brainchild of Curt Herzstark of Austria from the 1930s. The most interesting things about the design were the compactness and the complexity which baffled its first owners.

The contraption has setting sliders for input digits on the side of the main cylindrical body. A crank …read more

Building a Replica Final Cartridge III

The Commodore 64 was the computer of the 8-bit era, and remains the highest selling computer of all time. In addition to disk and tape drives, it also had a cartridge interface. A popular extension cartridge was the Final Cartridge III, which offered a variety of disk utilities and a GUI. [Greisi] was in possession of a no longer functional cartridge, and decided to reverse engineer the device.

[Greisi] started by desoldering all the ICs and mapping out a schematic for the board. The design centers around common parts for the era, such as a UV-erasable EPROM and some 74-series …read more

The Modern Retrocomputer: An Arduino Driven 6845 CRT Controller

[MmmmFloorPie] revived an old project to create the retro mashup of a 6845 CRT controller and a modern Arduino Uno. When it comes to chips, the Motorola 6845 is the great granddaddy of Cathode Ray Tube (CRT) interfaces. It was used in the IBM Monochrome display adapter, the Hercules graphics controller, CGA, Apple II terminal cards, and a host of other microcomputer and terminal systems.

Way back in 1989, [MmmmFloorPie] was a senior in college. His capstone project was a 68000 based computer which could record and playback audio, as well as display waveforms on a CRT. The CRT in …read more
