[Scott] acquired this broken trainer on eBay and then set about restoring it. The trainer provides I/O for programming, probing, and debugging an attached CPU. The first problem discovered when opening the case is that the CPU board is missing. The original board was an 80/10 but [Scott] ended up installing a newer 80/10A board he scored for fifty bucks. Later he upgraded to an 80/10B which increased the RAM and added a multimodule slot.
[Scott] has some luck fixing the failed power supply by recapping some of the smaller electrolytic capacitors which were showing high ESR. Once he had the board installed and the power supply functional he was able to input his first assembly program: a Cylon LED program! Making artistic use of the LEDs attached to the parallel port. You can see the results in the video embedded below.
When we last brought you word of the SS United States, the future of the storied vessel was unclear. Since 1996, the 990 foot (302 meter) ship — the largest ocean liner ever to be constructed in the United States — had been wasting away at Pier 82 in Philadelphia. While the SS United States Conservancy was formed in 2009 to support the ship financially and attempt to redevelop it into a tourist attraction, their limited funding meant little could be done to restore or even maintain it. In January of 2024, frustrated by the lack of progress, the owners of the pier took the Conservancy to court and began the process of evicting the once-great liner.

It was hoped that a last-minute investor might appear, allowing the Conservancy to move the ship to a new home. But unfortunately, the only offer that came in wasn’t quite what fans of the vessel had in mind: Florida’s Okaloosa County offered $1 million to purchase the ship so they could sink it and turn it into the world’s largest artificial reef.
The Conservancy originally considered it a contingency offer, stating that they would only accept it if no other options to save the ship presented themselves. But by October of 2024, with time running out, they accepted Okaloosa’s offer as a more preferable fate for the United States than being scrapped.
It at least means the ship will remain intact — acting not only as an important refuge for aquatic life, but as a destination for recreational divers for decades to come. The Conservancy has also announced plans to open a museum in Okaloosa, where artifacts from the ship will be on display.
Although the video game crash of the mid-80s caused a major decline in arcades from their peak popularity, the industry didn’t completely die off. In fact, there was a revival that lasted until the 90s with plenty of companies like Capcom, Midway, SEGA, and Konami all competing to get quarters, francs, loonies, yen, and other coins from around the world. During this time, Namco — another game company — built a colossal 28-player prototype shooter game. Eventually, they cut it down to a (still titanic) six-player game that was actually released to the world. [PhilWIP] and his associates are currently restoring one of the few remaining room-sized games that are still surviving.
Back in the olden days, there existed physical game stores, which in addition to physical games would also have kiosks where you could try out the current game consoles and handhelds. Generally these kiosks held the console, a display and any controllers if needed. After a while these kiosks would get scrapped, with only a very few ending up being rescued and restored. One of the lucky ones is a Game Boy kiosk, which [The Retro Future] managed to snag after it was found in a construction site. Sadly the thing was in a very rough condition, with the particle board especially being mostly destroyed.

These Game Boy kiosks also featured a special Game Boy, which – despite being super rare – also was hunted down. This led to the restoration, which included recovering as much of the original particle board as possible, with a professional furniture restore ([Don]) lending his expertise. This provides a master class in how to patch up damaged particle board, as maligned as this wood-dust-and-glue material is.
The boards were then reassembled more securely than the wood screws used by the person who had found the destroyed kiosk, in a way that allows for easy disassembly if needed. Fortunately most of the plastic pieces were still intact, and the Game Boy grey paint was easily matched. Next was reproducing a missing piece of art work, with fortunately existing versions available as reference. For a few missing metal bits that held the special Game Boy in place another kiosk was used to provide measurements.
After all this, the kiosk was powered back on, and it was like 1990 was back once again, just in time for playing Tetris on a dim, green-and-black screen while hunched half into the kiosk at the game store.
We all carry touch screen computers around in our pockets these days, but before the smartphone revolution, there was the personal digital assistant (PDA). While it wasn’t a commercial success, one of the first devices in this category was the Apple Newton. Today they’re sought after by collectors, although most of the ones surviving to this day need a bit of rework to the battery pack. Luckily, as [Robert’s Retro] shows, it’s possible to rebuild the pack with modern cells.
By modern standards, the most surprising thing about these battery packs is both that they’re removable and that they’re a standard size, matching that of AA batteries. The Newton battery pack uses four cells, so replacing them with modern rechargeable AA batteries should be pretty straightforward, provided they can be accessed. This isn’t as easy, though. In true Apple fashion the case is glued shut, and prying it apart can damage it badly enough so it won’t fit back in the tablet after repair is complete. The current solution is to cut a hatch into the top instead and then slowly work on replacing the cells while being careful to preserve the electronics inside.
[Robert’s Retro] also demonstrates how to spot weld these new AA batteries together to prepare them for their new home in the Newton case. With the two rows fastened together with nickel strips they can be quickly attached to the existing electrical leads in the battery pack, and from there it’s just a matter of snapping the batteries into the case and sliding it back into the tablet. If you’re looking for something a bit more modern, though, we’d recommend this Apple tablet-laptop combo, but it’s not particularly easy on the wallet.
Collecting retrocomputers is fun, especially when you find fully-functional examples that you can plug in, switch on, and start playing with. Meanwhile, others prefer to find the damaged examples and nurse them back to health. [polymatt] can count himself in that category, as evidenced by his heroic rescue of an 1993 IBM ThinkPad Tablet.
The tablet came to [polymatt] in truly awful condition. Having been dropped at least once, the LCD screen was cracked, the case battered, and all the plastics were very much the worse for wear. Many of us would consider it too far gone, especially considering that replacement parts for such an item are virtually unobtainable. And yet, [polymatt] took on the challenge nonetheless.
Despite its condition, there were some signs of life in the machine. The pen-based touch display seemed to respond to the pen itself, and the backlight sort of worked, too. Still, with the LCD so badly damaged, it had to be replaced. Boggling the mind, [polymatt] was actually able to find a 9.4″ dual-scan monochrome LCD that was close enough to sort-of fit, size-wise. To make it work, though, it needed a completely custom mount to fit with the original case and electromagnetic digitizes sheet. From there, there was plenty more to do—recapping, recabling, fixing the batteries, and repairing the enclosure including a fresh set of nice decals.
The fact is, 1993 IBM ThinkPad Tablets just don’t come along every day. These rare specimens are absolutely worth this sort of heroic restoration effort if you do happen to score one on the retro market. Video after the break.
[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.
The Atari ST flagged deleted files for overwriting but didn’t actively wipe them, allowing an undelete utility to work.
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?
