The story of Commodore computers is one of some truly great machines for their time, and of the truly woeful marketing that arguably spelled their doom. But there’s another Commodore computing story, that of the machines we never received, many of which came close enough to production  that they might have made it.

[Old VCR] has the story of one of these, and it’s a portable. It’s not a C64 like the luggable which did emerge, neither is it the legendary LCD portable prototype in the possession of our Hackaday colleague [Bil Herd]. Instead it’s a palmtop branded under licence from Toshiba, and since it’s a rare device even its home country of Japan the article gives us perhaps the only one we’ll ever see with either badge.

The Commodore HHC-4 was announced at Winter CES 1983, and since it was never seen again it’s aroused some curiosity among enthusiasts. The article goes to some lengths to cross-reference the visible features and deduce that it’s in fact a Toshiba Pasopia Mini, a typical palmtop computer of the era with not much in the way of processing power, a small alphanumeric display, and a calculator-style QWERTY keyboard. We’re treated to a teardown of a Toshiba unit and its dock, revealing some uncertainty about which processor architecture lurks in those Toshiba custom chips.

Looking at the magazine reviews and adverts it seems as though Commodore may have had some machines with their branding on even if they never sold them, so there exists the tantalizing possibility of one still lurking forgotten in the possession of a former staffer. We can hope.

If Commodore history interests you, you really should read [Bil]’s autobiographical account of the company in the 1980s.

[Neil] from The Cave, a computer and console gaming museum in the UK, has a treat for vintage computing and computer gaming enthusiasts. They received an important piece of game dev history from [Richard Costello], who coded ports of Gauntlet 2, Mortal Kombat, and Primal Rage for Atari ST and Amiga home computers. [Richard] brought them his non-functional Atari Mega ST in the hopes that they could get it working again, and demonstrate to visitors how game development was done back in the 80s — but sadly the hardware is not in the best shape.

That doesn’t stop [Neil], however. The real goal is seeing if it’s possible to re-create the development environment and access the game assets on the SCSI hard drive, and it’s not necessary to revive every part of the hardware to do that. The solution is to back up the drive using a BlueSCSI board which can act as a host, scan the SCSI bus, and dump any device it finds to an SD card. The drive didn’t spin up originally, but some light percussive maintenance solved that.

With the files pulled off the drive, it was time to boot it up using an emulator (which begins at the 16:12 mark). There are multiple partitions, but not a lot of files. There was one more trick up [Neil]’s sleeve. Suspecting that deleting everything was the last thing [Richard] did before turning the machine off decades ago, he fired up a file recovery utility. The Atari ST “deleted” files by marking them to be overwritten by replacing the first letter of the filename with a ‘bomb’ character but otherwise leaving contents intact. Lo and behold, directories and files were available to be undeleted!

[Neil] found some fascinating stuff such as mixed game and concept assets as well as what appears to be a copy of Ramrod, a never-released game. It’s an ongoing process, but with any luck, the tools and environment a game developer used in the 80s will be made available for visitors to experience.

Of course, modern retro gaming enthusiasts don’t need to create games the classic way; tools like GB Studio make development much easier. And speaking of hidden cleverness in old games, did you know the original DOOM actually had multi-monitor support hidden under the hood?

When making a birthday cake a bit more personal, one can create a novelty themed confection appropriate for the lucky recipient. In the case of [Spencer Owen], who you may know as the creator of the RC2014 retrocomputing ecosystem, it was appropriate to have one of the little machines at work somewhere, so [peahen] did just that. The result is a cake in the shape of an IMSAI 8080 microcomputer, but it does more than just look the part. This is a working replica of the classic machine, powered as you might expect by an RC2014 sitting next to it.

The lights are a set of addressable LEDs, and the switches are made from appropriately colored sweets. Sadly the plan to make these capacitive touch switched failed as the wiring became buried in the icing, but the LEDs deserve a second look. They’re encased in translucent heatshrink sleeving which is embedded under a layer of white icing, which is translucent enough, but on top for the classic panel light look are a set of edible cake-maker’s jewels. Best of all while all except the electronics is edible, the front panel is robust enough to have been removed from the cake in one and thus will live on.

We rather like the idea of electronics meeting sugarcraft, because fondant is a surprisingly versatile medium that deserves attention much further than just confectionery. We remember it being a popular cheap way to experiment with 3D printing back at the dawn of open source printers, and it still has some potential. Meanwhile if you’ve not seen the RC2014 we reviewed its original version back in 2016, and since then it’s evolved to become an ecosystem in its own right.

If you’re passionate about signal processing and retro tech, you’ll want to check out the Createc SC 01, a quirky handheld oscilloscope that recently caught the eye of [Thomas Scherrer] from OZ2CPU Teardown. This device, cheekily dubbed a “signal computer,” promises to be both intriguing and, perhaps, frustrating. You can view [Thomas]’ original teardown video here.

This device is packed with buttons and a surprisingly retro aesthetic that can make even the most seasoned hacker feel nostalgic. With a sample rate of 20 MHz and a bandwidth of up to 10 MHz, it’s a digital oscilloscope with a twist. Users may find its setup challenging, thanks to a somewhat convoluted manual that boasts numerous errors. However, beneath the confusion lies the potential for creative exploration: this signal computer can analyse analog signals, perform calculations, and even store data.

Despite its quirks, the SC 01 is sure the experience. Imagine troubleshooting a circuit while grappling with its unpredictable user interface—an adventure in itself for those who like a techy challenge.

The Createc SC 01 is not just another tool; it’s an invitation to embrace the imperfections of vintage tech. If you enjoy the hands-on learning process and don’t shy away from a few hiccups, this device might be something you’ll enjoy. Hackaday featured an article on similar devices last year.

Despite the rise of ARM processors in more and more computers from embedded systems to daily driver PCs, the x86 architecture maintains a stronghold in the computing space that won’t be going away anytime soon. One of the main drivers of this is its beachhead in industrial systems; the x86 architecture is backwards-compatible farther back than many of us have been alive and in situations where machines need to run for years with minimum downtime it’s good to know you can grab any x86 system off the shelf and it’ll largely work. This is also true for gaming, so if you’re like [Yeo Kheng Meng] and want to run games like DOOM natively on modern hardware it’s certainly possible, although there are a few catches.

This build goes into the design of a modern AMD Ryzen 5 desktop computer, with all of the components selected specifically for their use running software more than three decades old now. [Yeo Kheng Meng] is targeting DOS 6.22 as his operating system of choice, meaning that modern EFI motherboards won’t necessarily work. He’s turned to business class products as a solution for many of these issues, as motherboards targeting business and industrial customers often contain more support for antiquated hardware like PS/2 and parallel ports while still having modern amenities like DDR5 memory slots. PS/2 ports additionally are an indicator that the motherboard will supports older non-EFI boot modes (BIOS) and can potentially run DOS natively. Everything here can also run modern operating systems, since he isn’t building this system only to run DOS and retro games.

Beyond the motherboard choice, he’s also using a Soundblaster card for audio which is a design choice generally relegated to history, but still used in modern gaming by a dedicated group. There’s also a floppy drive running via a USB header adapter cable. Of course, there are a few problems running DOS and other era-appropriate software natively on such incomprehensibly fast hardware (by early 90s standards). Some video games were hard coded to the processor clock of the x86 process of the era, so increasing the clock speed orders of magnitude results in several playability issues. In emulators it’s easier to provide an artificially slow clock speed, but on real hardware this isn’t always possible. But [Yeo Kheng Meng] has done a lot to get this modern computer running older software like this. Another take we’ve seen for retro gaming on original hardware is this system which uses a brand-new 486 processor meant for use in industrial settings as well.

[Ctrl-Alt-Rees] bought something strange on an auction site: a Japanese Cefucom-21 from 1983. No? Didn’t ring a bell for us either. The legend on the front boldly proclaims: “CCI Multipurpose SLAP Computer,” so maybe it is some kind of computer, but it is definitely strange. For one thing, the “screen” isn’t a screen at all. [Rees] has found that it has something to do with teaching English. You can see the odd beast in the video below.

We don’t know how common these were in Japan, but they appear to be virtually unknown everywhere else. Inside is a Z80 computer based on a  Sanyo PHC-25, which is a little better known.

The strange screen is offset from the keyboard. There was also a tape drive and a ROM cartridge port. The screen, however, isn’t driven by the computer — you still needed a TV. Instead, it is a window to view a paper graphic stored on a special kind of cartridge. The cartridge simply had images printed on paper. The computer could roll the paper to an image.

Inside, the computer is a fairly conventional Z80 design but with many extras, including a second Z-80. Luckily, the battery, which is known to leak, didn’t completely blow out.

When the video was made, the old box wasn’t working. However, a comment on the video indicates that he’s since got it working and found the software for it, so we are looking forward to a hands-on video soon.

Have you seen one of these before? If you have, we are sure [Rees] would appreciate hearing from you. There seems to be a correlation between odd machines and dual Z-80s. We love seeing these old, forgotten machines.

We have probably all been there: that sudden memory of playing a (video) game and the good memories associated with said memory. Yet how advisable is it to try and re-experience those nostalgic moments? That’s what [Matt] of the Techmoan YouTube channel decided to give a whirl when he ordered the Arcade1Up Pong 2 Player Countercade game system. This comes loaded with multiple variants of the Pong game, including Pong Doubles and Pong Sports, in addition to Warlords, Super Breakout and Tempest. This unit as the name suggests allows for head-to-head two-player gaming.

This kind of ‘countercade’ system is of course much smaller than arcade versions, but you would expect it to give the Pong clones which [Matt] played as a youngster a run for their money at least. Ultimately [Matt] – after some multiplayer games with the Ms. – concluded that this particular nostalgia itch was one that didn’t have to be scratched any more. While the small screen of this countercade system and clumsy interface didn’t help much, maybe Pong just isn’t the kind of game that has a place in 2024?

From our own point of view of having played Pong (and many other ‘old’ games) on a variety of old consoles at retro events & museums, it can still be a blast to play even just Pong against a random stranger at these places. Maybe the issue here is that nostalgia is more about the circumstances of the memory and less of the particular game or product in question. Much like playing Mario Kart 64 on that 20″ CRT TV with three buddies versus an online match in a modern Mario Kart. It’s just not the same vibe.
