This MIDI BoomBox Takes Floppies

You might have had a boombox back in the 1990s, but probably not like the Yamaha MDP-10. As [Nicole] explains, the odd little device played MIDI files from a floppy disk. Technically, it wasn’t truly a boombox because it lacked batteries, but it sure looks like one.

The box also had a MIDI input jack, but no output. For an antique gadget, it is pretty impressive, but maybe not much by today’s standards. Of course, what we really wanted to see was what was inside. [Nicole] doesn’t disappoint.

The boombox brains are a pair of Hitachi H8 3000-series CPUs. The boards actually looks surprisingly modern until you notice the lack of integration. There are separate ROMs, RAMs, a floppy drive controller, and, of course, MIDI chips. Apparently, opening the box up is a challenge so [Nicole] suggests not doing it unless necessary. We assume it went back together with no problems.

There are lots of tidbits about peculiarities in the device. There are also, of course, recordings of the output and some comparisons from other devices. A great look into an old and odd piece of gear.

Since it has an input jack, you could connect it to — oh, we don’t know — maybe some spoons? Or a hurdy-gurdy.

Retro Hackintosh Made From Retro Parts

Apple as a company, has staked most of its future around being a “walled garden” where it controls everything from the hardware up through the user experience. In some ways this is good for users; the hardware is generally high quality and vetted by the company creating the software, making for a very uniform experience. This won’t stop some people from trying to get Apple’s operating systems and other software running on unapproved hardware though. These “Hackintosh” computers were much more common in the Intel era but this replica goes even further back to the Macintosh era.

Originally [Kevin] had ordered an authentic Macintosh with the intent of getting it working again, but a broken floppy disk drive and lack of replacement parts turned this project into a different beast. He used the Mac instead as a model for a new 3D-printed case, spending a ton of time sanding, filling, and finishing it to get it to look nearly indistinguishable from the original. The hardware going in this replica is an old Linux-based thin client machine running the Mini vMac operating system, with a modified floppy drive the computer uses to boot. A hidden SD card slot helps interface with modern computers. The display is a modern LCD, though a sheet of acrylic glued to the front panel replicates a bit of the CRT curve.

Flux Is Your Friend For Archiving Old Floppy Disks

Nothing screams retrocomputing quite like floppy drives. If you want to preserve some of your favorite computing memories like that paper you wrote about the joys of the Information Superhighway, [Shelby] from Tech Tangents has a detailed dive into how to preserve the bits off those old floppies.

Back in the day, the best way to get data off an old drive was to fire up an old computer. Now, with new devices specifically designed for harvesting data off of old floppies like the KryoFlux and the Greaseweazle, you can get the full flux map of the disk. With this, you can build binary image files and actually pull files and duplicate disks from vintage systems.

Some systems, like PCs, Macs, and Commodores are well-understood and are simple to preserve, while others take quite a bit of work to figure out. [Shelby] walks us through some of the more common disk formats as well as some real oddballs like Microsoft Adventure which features inconsistent formatting as a form of early DRM (boo).

Want to do your own preservation? We’ve covered a couple different methods in the past.

Reliving The Authentic 90s Linux Experience

Installing Linux on a modern PC has never been easier. There are tons of tools available that will nearly-automatically download your Linux distribution of choice, image a USB drive, and make it bootable so you can finally ditch your bloated, privacy-violating operating system and get the free performance boost that comes along with it. This wasn’t always the case, though. In the 90s you had to take a trip to a store (or library) and buy (or borrow) a boxed copy of some variety of Linux on floppy disk or CDs, and then install it on your own, often without the help of the Internet. [Action Retro] demonstrates this process for us so we don’t have to relive the pain ourselves.

Complete with a 90s-era Pentium machine enclosed in a beige case, this is really the full 90s experience. He’s found a boxed version of Red Hat version 5.2 with everything needed to get it up and running and, after a brief issue with the installer crashing because it couldn’t figure out the ZIP disk drive, had another era-appropriate experience by erasing the existing Windows 98 installation. This was before automatic partitioning tools were widely available, so it was a real risk for beginner Linux enthusiasts if they were trying to dual boot.

With the installation complete, the X window system still needed to be set up, as well as making sure the settings for the old CRT monitor were correct. With everything finalized, the system can really be explored. It includes out-of-the-box some software plenty of us would recognize today such as GIMP and some other software we might not, like Netscape Communicator. It’s a real time machine experience to get this operating system running on period-appropriate hardware, and a lot of features of modern Linux systems can still be seen especially if your modern distribution of choice still requires a lot of manual configuration during installation. Old operating systems aside, this machine might be capable of running a modern Linux distribution as well, provided it has something slightly newer than a 486.

Preserving Floppy Disks

Time is almost up for magnetic storage from the 80s and 90s. Various physical limitations in storage methods from this era are conspiring to slowly degrade the data stored on things like tape, floppy disks, and hard disk drives, and after several decades data may not be recoverable anymore. It’s always worth trying to back it up, though, especially if you have something on your hands like critical evidence or court records on a nearly 50-year-old floppy disk last written to in 1993 using a DEC PDP-11.

This project all started when an investigation unit in Maryland approached the Bloop Museum with a request to use their antique computer resources to decode the information on a 5.25″ floppy disk. Even finding a floppy disk drive of this size is a difficult task, but this was further compounded not just by the age of the disk but that the data wasn’t encoded in the expected format. Using a GreaseWeazle controlled by a Raspberry Pi, they generated an audio file from the data on the disk to capture all available data, and then used that to work backwards to get to the usable information.

After some more trials with converting the analog information to digital and a clue that the data on the disk was not fragmented, they realized they were looking at data from a digital stenography machine and were finally able to decode it into something useful. Of course, stenography machines are dark magic in their own right so just getting this record still requires a stenographer to make much sense out of it.

Using Excel To Manage A Commodore 64

The “save” icon for plenty of modern computer programs, including Microsoft Office, still looks like a floppy disk, despite the fact that these have been effectively obsolete for well over a decade. As fewer and fewer people recognize what this icon represents, a challenge is growing for retrocomputing enthusiasts that rely on floppy disk technology to load any programs into their machines. For some older computers that often didn’t have hard disk drives at all, like the Commodore 64, it’s one of the few ways to load programs into computer memory. And, rather than maintaining an enormous collection of floppy discs, [RaspberryPioneer] built a way to load programs on a Commodore using Microsoft Excel instead.

The Excel sheet that manages this task uses Visual Basic for Applications (VBA), an event-driven programming language built into Office, to handle the library of applications for the Commodore (or Commodore-compatible clone) including D64, PRG, and T64 files. This also includes details about the software including original cover art and any notes the user needs to make about them. Using VBA, it also communicates to an attached Arduino, which is itself programmed to act as a disk drive for the Commodore. The neceessary configuration needed to interface with the Arduino is handled within the spreadsheet as well. Some additional hardware is needed to interface the Arduino to the Commodore’s communications port but as long as the Arduino is a 5V version and not a 3.3V one, this is fairly straightforward and the code for it can be found on its GitHub project page.

With all of that built right into Excel, and with an Arduino acting as the hard drive, this is one of the easiest ways we’ve seen to manage a large software library for a retrocomputer like the Commodore 64. Of course, emulating disk drives for older machines is not uncommon, but we like that this one can be much more dynamic and simplifies the transfer of files from a modern computer to a functionally obsolete one. One of the things we like about builds like this, or this custom Game Boy cartridge, is how easy it can be to get huge amounts of storage that the original users of these machines could have only dreamed of in their time.

Floppy Disk Sales Are Higher-Density Than You Might Think

Floppies may be big in Japan, but nostalgic and/or needful Stateside floppy enthusiasts needn’t fret — just use AOL keyword point that browser toward floppydisk.com. There, you can buy new floppies of all sizes, both new and old, recycle your disks, or send them in to get all that precious vintage stuff transferred off of them.

That delightfully Web 1.0 site is owned by Tom Persky, who fancies himself the ‘last man standing in the floppy disk business’. Who are we to argue? By the way, Tom has owned that address since approximately 1990 — evidently that’s when a cyber-squatter offered up the domain for $1,000, and although Tom scoffed at paying so much as $1 for any URL, his wife got the checkbook out, and he has had her to thank for it ever since.

My business, which used to be 90% CD and DVD duplication, is now 90% selling blank floppy disks. It’s shocking to me. — Tom Persky

In the course of writing a book all about yours-truly’s favorite less-than-rigid medium, authors Niek Hilkmann and Thomas Walskaar sat down to talk with Tom about what it’s like to basically sell buggy whips in the age of the electric car.

Tom also owns diskduper.com, which is where he got his start with floppies — by duplicating them. In the 80s and 90s, being in this business was a bit like cranking out legal tender in the basement. As time wore on and more companies stopped selling floppies or simply went under, the focus of Tom’s company shifted away from duplication and toward sales. Whereas the business was once 90% duplication and 10% floppy sales, in 2022, those percentages have flopped places, if you will.
