FrogFind Grabs The WAP

July 23, 2025 by Tyler August 25 Comments

Yes, the Wireless Application Protocol! What other WAP could there possibly be? This long-dormant cellphone standard is now once again available on the web, thanks to [Sean] over at ActionRetro modifying his FrogFind portal as a translation engine. Now any web site can be shoved through the WAP!

WAP was rolled out in 1999 as HTML for phones without the bandwidth to handle actual HTML. The idea of a “mobile” and a “desktop” site accessed via HTTP hadn’t yet been conceived, you see, so phoning into sites with WAP would produce a super-stripped down, paginated, text-only version of the page. Now FrogFind has a WAP version that does the same thing to any site, just as the HTTP (no S!) FrogFind translates the modern web into pure HTML vintage browsers can read.

Of course you’ll need a phone that can connect to FrogFind with a WAP browser, which for many of us, may be… difficult. This protocol didn’t last much longer than PETS.COM, so access is probably going to be over 2G. With 2G sunset already passed in many areas, that can be a problem for vintage computer enthusiasts who want to use vintage phone hardware. [Sean] does not have an answer — indeed, he’s actively searching for one. His fans have pointed out a few models of handsets that should be able to access WAP via WiFi, but that leaves a lot of retro hardware out in the cold. If you have a good idea for a 2G bridge that can get out to the modern web and not attract the angry attention of the FTC (or its local equivalent), fans of ActionRetro would love to hear it — and so would we!

Vintage phone hacks don’t show up often on Hackaday, and when they do, it’s either much older machines or upgrading to USB-C, not to modern communications protocols. We haven’t seen someone hacking in the WAP since 2008. Given the collective brainpower of the Hackaday commentariat, someone probably has an idea to let everyone dive right into the WAP. Fight it out in the comments, or send us a tip if you have link to a howto.

Game Dev On IBook G4 With NetBSD

July 23, 2025 by Tyler August 5 Comments

What can you do with a laptop enough to drink even in the Puritan ex-colonies? 21 years is a long time for computer hardware– but [Chris] is using his early-2004 iBook G4 for game dev thanks to NetBSD.

Some of you might consider game dev a strong word; obviously he’s not working on AAA titles on the machine he affectionately calls “Brick”. NetBSD includes pygame in its repositories, though, and that’s enough for a 2D puzzle game he’s working on called Slantics. It’s on GitHub, if you’re curious.

Slantics: possibly the only game written on PPC Macintosh hardware this year.

Why NetBSD? Well, [Chris] wants to use his vintage hardware so that, in his words “collecting does not become hoarding” and as the slogan goes: “Of course it runs NetBSD!” It’s hard to remember sometimes that it’s been two decades since the last PPC Macintosh. After that long, PPC support in Linux is fading, as you might expect.

[Chris] tried the community-supported PPC32 port of Debian Sid, but the installer didn’t work reliably, and driver issues made running it “Death by a thousand cuts”. NetBSD, with it’s institutional obsession with running on anything and everything, works perfectly on this legally-adult hardware. Even better, [Chris] reports NetBSD running considerably faster, getting 60 FPS in pygame vs 25 FPS under Linux.

This is almost certainly not the year of the BSD Desktop, but if you’ve got an old PPC machine you feel like dusting off to enjoy a low-powered modern workflow, NetBSD may be your AI-code-free jam. It’s great to see old hardware still doing real work. If you’d rather relive the glory days, you can plug that PPC into a wayback proxy to browse like it’s 2005 again. If you get bored of nostalgia, there’s always MorphOS, which still targets PPC.

Video Tape Hides Video Player

July 22, 2025 by Tyler August 16 Comments

While it might not be accurate to say VHS is dead, it’s certainly not a lively format. It continues on in undeath thanks to dedicated collectors and hobbyists, some of whom may be tempted to lynch Reddit user [CommonKingfisher] for embedding a video player inside a VHS tape.

Miniaturization in action. The video player probably cost about the same as the original VHS when you account for inflation.

The hack started with a promotional video card via Ali Express, which is a cheap enough way to get a tiny LCD player MP4 playing micro. As you can see, there was plenty of room in the tape for the guts of this. The tape path is obviously blocked, so the tape is not playable in this format. [CommonKingfisher] claims the hack is “reversible” but since he cut a window for the LCD out of the casing of the cassette, that’s going to be pretty hard to undo. On the other hand, the ultrasonic cutter he used did make a very clean cut, and that would help with reversibility.

The fact that the thing is activated by a magnetic sensor makes us worry for the data on that tape, too, whether or not the speaker is a peizo. Ultimately it doesn’t really matter; in no universe was this tape the last surviving copy of “The Matrix”, and it’s a lot more likely this self-playing “tape” gets watched than the VHS was going to be. You can watch it yourself in the demo video embedded below.

VHS nostalgia around here usually involves replicating the tape experience, rather than repurposing the tape. We’re grateful to [George Graves] for the tip. Tips of all sorts are welcome on our friendly neighborhood tips line.

2025 One Hertz Challenge: A 555, But Not As We Know It

July 22, 2025 by Tyler August 2 Comments

We did explicitly ask for projects that use a 555 timer for the One Hertz Challenge, but we weren’t expecting the 555 to be the project. Yet, here we are, with [matt venn]’s Open Source 1Hz Blinky, that blinks a light with a 555 timer… but not one you’d get from Digikey.

Hooking a 555 to blink an LED at one hertz is a bog-simple, first-electronics-project type of exercise, unless you have to make the 555 first. Rather than go big, as we have seen before, [matt venn] goes very small, with a 555 implemented on a tiny sliver of Tiny Tapeout 6.

We’ve covered projects using that tapeout before, but in case you missed it, Tiny Tapeout gives space to anyone to produce ASICs on custom silicon using an open Process Design Kit, and we have [matt venn] to thank for it. The Tiny Tapeout implementation of the 555 was actually designed by [Vincent Fusco].

Of course wiring it up is a bit more complicated than dropping in a 555 timer to the circuit: the Tiny Tapeout ASIC must be configured to use that specific project using its web interface. There’s a demo video embedded below, with some info about the project– it’s not just a blinking LED, so it’s worth seeing. The output isn’t exactly One Hertz, so it might not get the nod in the Timelord category, but it’s going to be a very strong competitor for other 555-based projects– of which we could really use more, hint-hint. You’ve got until August 19th, if you think you can use a 555 to do something more interesting than blink an LED.

Remembering Chiptunes, The Demoscene And The Illegal Music Of Keygens

July 20, 2025 by Tyler August 39 Comments

We loved keygens back in the day. Our lawyers advise us to clarify that it’s because of the demo-scene style music embedded in them, not because we used them for piracy. [Patch] must feel the same way, as he has a lovely historical retrospective out on “The Internet’s Most Illegal Music” (embedded below).

After defining what he’s talking about for the younger set, who may never have seen a keygen in this degenerate era of software-by-subscription, [Patch] traces the history of the jaunty chiptunes that were so often embedded in this genre of program. He starts with the early demoscene and its relationship with cracker groups — those are coders who circulate “cracked” versions of games, with the copyright protection removed. In the old days, they’d embed an extra loading screen to take credit for the dastardly deeds that our lawyer says to disavow.

SymbOS Is A Funhouse Mirror Look At A Future That Never Was

July 19, 2025 by Tyler August 66 Comments

The Z80 might be decades obsolete and a few years out of production, but it’s absolutely a case of “gone but not forgotten” in the hacker world. Case in point is SymbOS, a multitasking OS for Z80 machines by Amstrad, Sinclair, and the MSX2 family of computers that updated to version 4.0 earlier this year.

The best way to describe SymbOS is like looking at an alternate reality where Microsoft created Windows 95 ten years early to put on the MSX instead of the BASIC they were paid to provide. SymbOS 4.0 comes even further into alignment with that design language, with a new file explorer that looks a lot like Windows Explorer replacing (or supplementing) the earlier Midnight Commander style utility in version 3.

Thanks to the preemptive multitasking, you can listen to tracker music while organizing files and writing documents, and even play a port of DOOM. Chat with your friends on IRC while watching (low res) videos on SymboVid. If you’re looking for productivity, all the old business software written for CP/M can run in a virtual machine. There’s even an IDE if you can stand the compile times on what is, we have to remember, an 8-bit, 1980s machine. It’s hard to remember that while watching the demo video embedded below.

The operating system supports up to 1024 KB of RAM (in 64 KB chunks, of course) and file systems up to 2 TB, which is an absolutely bonkers amount of space for this era’s machines. One enterprising dev has even got his CPC talking to ChatGPT, if that’s your jam. You can try SymbOS for free online on an MSX emulator, or toss it onto a spare Raspberry Pi. If you’re feeling adventurous, there’s a port in the works for the Isetta TLL retrocomputer.

This isn’t the first modern OS we’ve featured for the Z80, the processor which will live forever in our hearts and tapeouts.

Thanks to [Manuel] for the tip.

PicoGUS Adds CD-ROM Emulation To ISA Bus

July 19, 2025 by Tyler August 29 Comments

Everything fails eventually, but moving parts fail fastest of all– and optical drives seemingly more than others, at least in our experience. Even when they work, vintage drives often have trouble with CD-R, and original media isn’t always easy to find. That’s why it’s so wonderful that [polpo]’s RP2040 ISA card, the PicoGUS 2.0, now supports CD-ROM emulation.

We covered PicoGUS when it first appeared as an ISA sound card, and make no mistake, it can still emulate sound cards for retro-PC beeps and boops. It’s not just the Gravis Ultrasound (GUS) from which the project took its name, but Sound Blaster 2.0, MPU-401 for MIDI, Tandy 3-voice, and CMS/GameBlaster are all soft options. Like most sound cards back in the day, PicoGUS provides game port support as well.
