Quake 2 Ported To Apple Watch

September 6, 2023 by Bryan Cockfield No comments

DOOM always seems to spontaneously appear on any new device the day it’s released. From printers to industrial robots to pregnancy tests, it always makes its way on anything with an integrated circuit and a screen. But that’s not the only 90s video game with a cult following and and ability to run on hardware never intended for gaming. The early Quake games are still remarkably popular, and the second installment of this series was recently brought to the Apple Watch thanks to [ByteOverlord].

Building this classic for the Apple Watch requires using the original Quake files and some work with Xcode to get a package together that will run on the wrist-bound computer. There are a few other minimum system requirements to meet as well, but with all of that out of the way the latest release runs fairly well on this small watch. The controls have been significantly modified to use the Apple’s touch screen and digital crown instead of any peripherals, and as a result it’s not likely you’d win any matches if it was possible to cross-play with PC users with a setup like this, but it’s definitely playable although still missing a few features compared to the PC version.

This actually isn’t the first Quake game to be ported to the Apple Watch, either. The first version of Quake ran on this device thanks to [MyOwnClone]’s efforts a little over a year ago. It’s also not the first time we’ve seen Quake running on unusual Apple hardware, either. Take a look at this project which uses one of the early iPods to play this game, along with the scroll wheel for a one-of-a-kind controller.

Thanks to [Joni] for the tip!

Hackaday Links: July 2, 2023

July 2, 2023 by Dan Maloney 21 Comments

Members of Pixelbar woke up to shocking news on Wednesday morning this week as they learned that a fire had destroyed the building housing their Rotterdam hackerspace. Pictures of the fire are pretty dramatic and show the entire building ablaze. We’re not familiar with Pixelbar specifically, but most hackerspaces seem to share space with other businesses in repurposed warehouses and other industrial buildings, and it looks like that was the case here. Local coverage doesn’t indicate that a cause has been determined, but they do say that “large batches of wood” were stored in or near the structure, which likely contributed to the dramatic display. There don’t seem to be reports of injuries to civilians or first responders, so that’s a blessing, but Pixelbar seems to have been completely destroyed. If you’re in a position to help, check out their GoFundMe page. As our own Jenny List, who currently lives in The Netherlands, points out, spaces suitable for housing a hackerspace are hard to come by in a city like Rotterdam, which is the busiest port in Europe. That means Pixelbar members will be competing for space with businesses that have far deeper pockets, so anything you can donate will likely go a long way toward rebuilding.

Increasing System Memory With The Flick Of A Switch

June 5, 2023 by Bryan Cockfield 17 Comments

There’s an apocryphal quote floating around the internet that “640K ought to be enough memory for anybody” but it does seem unlikely that this was ever actually said by any famous computer moguls of the 1980s. What is true, however, is that in general more computer memory tends to be better than less. In fact, this was the basis for the Macintosh 512k in the 1980s, whose main feature was that it was essentially the same machine as the Macintosh 128k, but with quadruple the memory as its predecessor. If you have yet to upgrade to the 512k, though, it might be best to take a look at this memory upgrade instead.

The Fat Mac Switcher, as it is called by its creator [Kay Koba], can upgrade the memory capability of these retro Apple machines with the simple push of a switch. The switch and controller logic sit on a separate PCB that needs to be installed into the computer’s motherboard in place of some of the existing circuitry. The computer itself needs its 16 memory modules replaced with 41256 DRAM modules for this to work properly though, but once its installed it can switch seamlessly between 512k and 128k modes.

Another interesting quirk of the retro Macintosh scene is that the technically inferior 128k models tend to be valued higher than the more capable 512k versions, despite being nearly identical otherwise. There are also some other interesting discussions on one of the forum posts about this build as well. This module can also be used in reverse; by installing it in a Macintosh 512k the computer can be downgraded to the original Macintosh 128k. For this the memory modules won’t need to be upgraded but a different change to the motherboard is required.

A product like this certainly would have been a welcome addition in the mid 80s when these machines were first introduced, since the 512k was released only months after the 128k machines were, but the retrocomputing enthusiasts should still get some use out of this device and be more able to explore the differences between the two computers. If you never were able to experience one of these “original” Macintosh computers in their heyday, check out this fully-functional one-third scale replica.

FPS Game Engine Built In Ancient Macintosh HyperCard Software

January 27, 2023 by Lewin Day 14 Comments

Wolfenstein 3D and Doom are great examples of early FPS games. Back in that era, as Amiga was slowly losing its gaming supremacy to the PC, Apple wasn’t even on the playing field. However, [Chris Tully] has used the 90s HyperCard platform to create an FPS of his own, and it’s charming in what it achieves.

If you’re not familiar with it, HyperCard was a strange combination of database, programming language, and graphical interface system all rolled into one. It made developing GUI apps for the Macintosh platform simpler, with some limitations. It was certainly never intended for making pseudo-3D video games, but that just makes [Chris’s] achievement all the more impressive.

At this stage, [Chris’s] game doesn’t feature any NPCs, weapons, or items yet. It’s thus more of a First Person Walker than First Person Shooter. It features four small rooms with perpendicular, vertical walls, rendered either greyscale or 8-bit color. Now that he’s got the basic engine running, [Chris] is looking to recreate a bit of a Doom RPG experience, rather than copying Doom itself. He hopes to add everything from monsters to weapons, lava, and working HUD elements. If you want to dive in to the code, you can – HyperCard “stacks”, as they’re known, are made up of readily editable scripts.

[Chris] built the project to celebrate the aesthetic and limitations of the original Mac platform. While it could technically run on original hardware, it would run incredibly slowly. It currently takes several seconds to update the viewport on an emulated Mac Plus with 4MB of RAM. Thankfully, emulation on a modern PC can be sped up a lot to help the framerate.

We love seeing HyperCard pushed far beyond its original limits. We’ve seen it before, too, such as when it was used on a forgotten 90s Apple phone prototype. If you’ve been hacking away on retro software yourself, we’d love to see your projects on the tipsline!

Mac 128K Emulator Gets DIY Ceramic Enclosure

October 6, 2022 by Lee Wilkins 8 Comments

Creative technologist [Joselyn McDonald] wanted to hone her ceramic skills by building an iconic Macintosh 128K sculpture, complete with a fully functional operating system.

At first, she was determined to use Processing to create an interface for her sculpture by recreating the UI visually and adding some touch controls. However, she soon abandoned this tedious task after discovering MacintoshPi, which steps you through installing Mac OS 7, 8, and 9 emulators on a Raspberry Pi. [Joselyn] has also installed several retro games, including DOOM II, Carmen Sandiego, and Sim City, thanks to sites like Macintosh Garden and Macintosh Repository.

Next, [Joselyn] hopes to set it up to display her and her partner’s schedules, and to let friends play around with nostalgic games. This piece was made using hand building, but other cool ceramic techniques like this slip cast dog bowl and this stone 3D printer have us thinking about what other types of enclosures could be built!

Want To Use A Classic Mac Mouse On A Modern Computer? No? Here’s How To Do It Anyway

August 11, 2022 by Donald Papp 23 Comments

Need to hook a classic Mac mouse up to your modern machine with the help of a DIY USB adapter? [John Floren] has you covered. [John]’s solution uses a board with an ATmega32U4 microcontroller on it to connect to the Mac mouse on one end, and emulate a USB HID (Human Interface Device) on the other. A modern machine therefore recognizes it like it would any other USB input device.

Why is this necessary? The connector on the classic Mac mouse may look like a familiar DE-9 connector, but it is not an RS-232 device and wouldn’t work if it were plugged into a 9-pin serial port. The classic Mac mouse uses a different pinout, and doesn’t have much for brains on the inside. It relies on the host computer to read its encoders and button states directly.

This project is actually a bit of an update to a piece of earlier work [John] did in making a vintage Depraz mouse work with modern systems. He suspected that it wouldn’t take much to have it also work with a classic Mac mouse, and he was right — all it took was updating the pin connections and adding some pull-up resistors. The source code and design files are on GitHub.

Even if one does not particularly want to use a classic Mac mouse for daily work, there’s definitely value in this kind of thing for those who deal in vintage hardware: it allows one to function-check old peripherals without having to fire up a vintage machine.

Porting DOOM To A Forgotten Apple OS

June 9, 2022 by Bryan Cockfield 28 Comments

Apple hasn’t always had refined user experiences in their operating systems. In the distant past of the ’90s they were still kind of clunky computers that were far from the polished, high-end consumer machines of the modern era. That wasn’t all that Apple offered back then, though. They had a long-forgotten alternative operating system that was called A/UX designed for government applications, and [Keriad] is here to show us this relic operating system and port DOOM to it.

A/UX was designed in the pre-PowerPC days when Macintosh computers ran on Motorola 68000 chips. Luckily, [Keriad] has a Mac Quadra 800 with just such a chip that is still fully-functional. DOOM was developed with the NeXTSTEP operating system which can run on old Macs thanks to another tool called MacX which allows X11 applications to run on Mac. A version of gcc for A/UX was found as well and with the source code in hand they were eventually able to compile a binary. There were several hiccups along the way (including the lack of sound) but eventually DOOM was running on this forgotten operating system.

The main problem with the build in the end, besides the lack of sound, is that the game only runs at 2 – 3 frames per second. [Keriad] speculates that this is due to all of the compatibility layers needed to compile and run the game at all, but it’s still impressive. As far as we know, [Keriad] is the first person to port DOOM to this OS, although if you’re looking for something more straightforward we would recommend this purpose-built Linux distribution whose sole task is to get you slaying demons as quickly as possible.
