A Trackball Retro Laptop

August 19, 2024 by Navarre Bartz 6 Comments

While track pads and mice dominate the pointing device landscape today, there was a time when track balls were a major part of the scene. In order to really sell the retro chops of his portable computer, [Ominous Industries] designed a clip-on style track ball for his retro Raspberry Pi laptop.

Starting with a half circle shape, he designed the enclosure in Fusion360 to house the guts of a USB trackball. Using the pattern along a path feature of the software, he was able to mimic the groovy texture of the main device on the trackball itself. Flexures in the top of the track ball case with pads glued on actuate the buttons.

We appreciate the honesty of the cuts showing how often the Pi can get grumpy at the extra wide display in this video as well as the previous issues during the laptop build. The bezel around the screen is particularly interesting, being affixed with magnets for easy access when needing to work on the screen.

Retro portables are having a moment. We just covered the Pi Portable 84 and previously saw one inspired by the GRiD Compass . If you’re more interested in trackballs, maybe give this trackball ring or the Ploopy trackball a look?

Printed Portable Computer Inspired By The Classics

July 28, 2024 by Tom Nardi 3 Comments

These days, laptop computers are all more or less the same, at least externally. Some are thicker than others, they might come in different colors, or with a 360° hinge that lets you flip the screen around the back and use it as a tablet, but overall they’ve all got the same shape and proportions. The industry, and indeed the users, eventually agreed on the best way to make a computer portable and are now fully committed to it.

But that wasn’t always the case. In the 1980s there were a number of laptops from the likes of Toshiba, Tandy, and even IBM that took a slightly different approach to the clamshell design. These computers featured ultra-wide displays with a hinge located closer to the center of the computer, giving the machine a distinctive “trunk” in the back. It’s these classic machines that clearly inspired [Michael Mayer] to design the Portable Pi 84.

[Michael] says that the 3D printed enclosure was largely designed around the 40% ortholinear keyboard, which itself is based on the Happy-Keyboard from [Luis Alegría]. The rest apparently just fell into place, such as the fact that the 1600 x 600 Waveshare 9.3 inch display happens to be almost the perfect size to cover the keyboard below it.

Compared to many of the other custom computer builds we’ve covered, the rear compartment of the Portable Pi 84 provides ample free space for the various system components. That includes the Raspberry Pi 4 that runs the show, a UPS “hat” that powers the system via a pair of 21700 batteries, and even a set of amplified speakers. It looks like there’s still plenty of room in the back for additional gear, such as an RTL-SDR or perhaps even a cartridge slot.

A particularly nice feature of this build are the inset panels on the rear of the machine, which allow for the various ports and connectors to be reconfigured by the user without having to re-print the entire case — one could imagine a replacement panel that features a connector for an external WiFi antenna, for example. We also like the use of heat-set inserts throughout the case, which will not only make the build sturdier, but means the case can be opened and closed regularly without fear of stripping out the screw holes.

So is this a computer or a cyberdeck? It’s hard to say. We tend to think that a proper deck needs to have a more unique physical layout, and technically this form factor was actually fairly popular at one point. But whatever you want to call builds like this, we’re stoked to see them become more common and better documented. Long live the truly personal computer.

Luggable Cyberdeck Can Still Be A Luggable PC

March 4, 2024 by Kristina Panos 3 Comments

In the 80s and early 90s, there existed a class of personal computers that are no longer around today — the luggable. Planted firmly between a desktop and a laptop, these machines were lovingly called so because they were portable, but just barely. Think Kaypro, Osborne, or the Compaq Portable.

First things first — this lovely 1990-era industrial luggable has not been gutted according to [D1g1t4l_G33k]. The chassis, CRT, power supply, and ISA backplane are original and still intact, and they still have all the parts to restore it to its original DOS 3.1 form.

What [D1g1t4l_G33k] did do is replace the 386x-based ISA SBC with a 2005 AMD LX-600 Geode at 366 MHz. Gone are the ISA data acquisition cards and 80 MB SCSI hard drive, replaced with a 32 GB compact flash drive. The floppy drive is functional, too. Now it sits on a cart next to the workbench running AntiX Core 19.5, functioning happily as an AVR development workstation.

Having an old luggable to mess with in the first place isn’t a requirement. We’ve seen a modern take on the luggable, and here’s one with three monitors.

This CRT Luggable Makes Sense

August 28, 2023 by Jenny List 3 Comments

There was a time when portable computing meant not a svelte laptop but a suitcase-sized machine that was really a slimmed-down desktop with a small CRT incorporated int he same box. They were heavy and unwieldy, but the computing compromises of using one at the time were less than with what served for more portable machinery. It’s a form factor which understandably has long ago disappeared, but that hasn’t stopped [Sdomi] from reviving it with a machine that packs plenty of modern computing power.

It’s a project that started with a monitor, a diminutive green-screen model which had previously adorned a CNC machine. It’s a composite model, so it’s driven from a VGA-to-composite converter. The computing power comes from a thin-client board that packs an up-to-date AMD Ryzen processor and 32 GB of memory, and the case is manufactured from oriented strand chipboard.

The result is a chunky but definitely practical and usable take on a portable cyberdeck, with the caveat that a composite monitor will not deliver the resolution some of us might be used to. We have to admit rather liking it, there’s nothing like the curved glass of a CRT.

It’s by no means the only up to date luggable we’ve seen, though more often now they feature an LCD.

TRS-80 Luggable Gets Fresh Face, New Gear

June 16, 2022 by Tom Nardi 10 Comments

It’s true that this TRS-80 Model 4P “luggable” was in better shape than many of the vintage machines that pass through the hands of [Drygol], but that doesn’t make the end result of its refurbishment and upgrade process any less impressive. After all, not every rebuild has to be a once-in-a-lifetime achievement.

No, the case didn’t have to get pieced back together by hand, and the board didn’t need to have half of its traces recreated. But the outer plastic was certainly in need of a good retrobright treatment, the keyboard was overdue for a cleaning, and the capacitors in the PSU were predictably due for retirement. After [Drygol] got through with it, the machine was back in like-new condition. But then, we can do a little better than that…

So into the refreshed computer went several community-developed modifications, including a M3SE expander that adds Compact Flash and Ethernet support to the TRS-80 and a high-resolution Grafyx video board. In classic [Drygol] style, every effort was made to integrate these upgrades as seamlessly as possible. After struggling for a bit to find a 5.25″ drive that would write a disk the TRS-80 would actually read, all the necessary files to get the upgrades working were transferred over, and the system was booting into TRSDOS.

We’ve covered a lot of [Drygol]’s restorations, and never get tired of seeing how these old and broken machines get a new lease on life once they come out the other end. Whether it’s a relatively easy task of swapping out some dud chips, or using every trick in the book to piece together what’s left of a computer’s case, they always show an incredible level of dedication and attention to detail that you can’t help but admire.

Old Portable TV Becomes Unique CRT Cyberdeck

February 28, 2022 by Dan Maloney 10 Comments

Remember the “suitcase” form-factor for PCs? In the time before latops, these luggable machines were just the thing for the on-the-go executive. OK, maybe not really — but the ability to have PC, monitor, and peripherals in a single package had real appeal, and a lot of that rationale is behind the cyberdeck phenomenon. So when we saw this retro portable TV turned into a cyberdeck, it really caught our eye.

Ironically, the portable black-and-white TV that [Lucas Dul] chose as the basis for his cyberdeck hails from about the same period in time that luggable PCs were having their brief time in the sun. Scored from eBay, the Magnavox TV/radio combo had seen better days, and required a bit of surgery to repair what might have been drop damage. With the CRT restored and the video and audio paths located, the TV got a Raspberry Pi, a small touchpad, and a couple of concealed USB connectors. The Pi’s composite output drives the CRT, with about the results you’d expect. The keyboard appears to be just about the right size to serve as a cover, but [Lucas] said that’s a future project.

Still, with the TV’s original handle acting as a stand, this cyberdeck gives off a real Compaq or IBM portable PC vibe. We’ve seen a few luggable-lookalike cyberdecks before, but none that dared use a CRT monitor. It may be a far cry from HDMI, but we really appreciate that [Lucas] chose this way rather than slapping in an LCD.

An All In One Cube PC For A 1990s That Never Quite Happened

December 20, 2021 by Jenny List 12 Comments

When a particular device or appliance is evoked, there comes with it a set of expectations over what it might look like. A toaster, a camera, a washing machine, or a PC, will all have their own accepted form factors, and it’s rare that a manufacturer is adventurous enough to venture outside them. In the world of PCs there was a brief flowering of this type of creativity through the 1990s, and it’s that time which [ikeji]’s cube PC squarely fits in. It’s a 3D printed PC with a built-in display, keyboard, and printer, and while some might categorize it as a cyberdeck we’d say it goes further, we could easily imagine a slightly more polished version being an object of desire back when a powerful machine carried an 80486.

Inside it’s no slouch, packing an AMD Ryzen 7 Pro on a Mini-ITX motherboard, and while the display is a mere 7-incher it fits neatly behind the fold-down keyboard. The thermal printer is maybe more of a toy, but it’s good to find that even a bleeding-edge motherboard still has a serial port on it somewhere that it can talk to.

While the build undoubtedly has a few home-built rough edges we like the idea, echoing as it does those all-in-ones from the CRT era. Unless you have a handy Minitel terminal you won’t find much like it.
