Custom PC Issue 232My Hobby Tech column this month takes a look at something cutting-edge and something vintage: the Jolly Module drop-in Arduino Uno upgrade and Shareware Heroes, Richard Moss’ latest look at a bygone era of software.

The Jolly Module is an interesting beast. Created by Gianluca Martino, one of the founding members of the Arduino team, it’s designed to address a very real problem: drawers packed with Arduino Uno development boards which have been made obsolete by modern equivalents boasting integrated Wi-Fi networking. Thus, the Jolly Module: pop out the ATmega328 microcontroller in the socket on top of the Arduino Uno and put the Jolly Module in its place and you can do everything you used to do with the added benefit of Wi-Fi connectivity.

It’s not a perfect device, by any means. Its pricing means that you could be better off buying something like a Raspberry Pi Pico W or an ESP32-based board, unless you’re tied into the Arduino Uno form factor already, while it doesn’t quite fit as well as it should – and strains the socket to the point where you can’t go back to the original ATmega328 chip. It’s clever, though, and for those with Arduino Uno shields to spare can mean a whole new lease of life for otherwise-abandoned hardware.

Shareware Heroes, meanwhile, is the follow-up to Moss’ The Secret History of Mac Gaming, which I reviewed back in Issue 196. This time, Moss turns his attention to shareware software – that bygone era before high-speed internet made distribution a non-issue, when the easiest way for a software house to get its wares in peoples’ hands was to encourage them to copy and distribute it among themselves. As with its precursor, Shareware Heroes is a fantastically well-researched tome and a delight to read – and comes with the added benefit of a DOS-themed website providing access to a full bibliography and reference database.

Finally, I also cover two bits of news in the column: Framework announcing the release of its first modular laptop design for Google’s Chromebook platform, and the launch of an upgrade module for the Clockwork Pi DevTerm (reviewed in Issue 222) which offers compatibility with the Raspberry Pi Compute Module 4 family.

Custom PC Issue 222This month’s five-page Hobby Tech column takes a look at the retro-style Clockwork Pi DevTerm portable computer, the HcX Floppy Disk Emulator tool, and Hex Loader – the first graphic novel I’ve seen in a few decades to arrive with its own tie-in game for the Sinclair ZX Spectrum.

The DevTerm, a follow-up to Clockwork Pi’s excellent GameSHell hand-held console, has been a little delayed. Having originally been due to land in April 2021, it’s only now gone through the review process thanks to the ongoing component shortages afflicting the industry – but it’s definitely been worth the wait. Inspired by classic portable computers like the TRS-80 Model 100, it’s a real anachronism backed by open-source hardware and open-source software.

That’s not to say it’s perfect: the top-end A-0604 model, as reviewed, is incapable of sustaining full-speed operation for more than a few seconds of load before throttling and arrives with the two high-performance cores entirely disabled; the display suffers from a glitch whereby the top four lines are entirely missing; and it took the community to make the tiny trackball less frustrating to use. The sheer joy of the device, thankfully, overrides these concerns. The built-in thermal printer is particularly wonderful, and was used to submit this month’s column – by post.

The HcX Floppy Disk Emulator review, meanwhile, was born from a need I had to image and retrieve data from some floppy disks which had been formatted for use with the Dragon Data family of microcomputers. Despite its name, the software isn’t exclusively usable by those who’ve splashed out on HcX hardware: it can load disk images, including stream captures from a KryoFlux, and provides a range of useful tools including an incredible visual floppy disk explorer – capable of even demonstrating the exact location and shape of damaged areas of a disk.

Finally, Hex Loader. A crowdfunded collaboration between writer Dan Whitehead, illustrator Conor Boyle, and letterer Jim Campbell, Hex Loader is halfway a love-letter to game development in the 1980s and halfway some kind of scathing indictment of consumerism and modern art wrapped in a mystical layer of sorcery. It also comes complete with a tie-in ZX Spectrum game, Combat Wombat – and you can’t say that of many publications released in the 2020s.
