Reliving The Authentic 90s Linux Experience

November 8, 2023 by 65 Comments

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

September 15, 2023 by 36 Comments

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

June 8, 2023 by 16 Comments

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

September 21, 2022 by 53 Comments

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.

Floppy Disk Sings: I’m Big In Japan

September 13, 2022 by 66 Comments

The other day, a medical office needed my insurance card. I asked them where to e-mail it and they acted like I had offered them human flesh as an appetizer. “We don’t have e-mail! You have to bring it to us in person!” They finally admitted that they could take a fax and I then had to go figure out how to get a free one page fax sent over the Internet. Keep in mind, that I live in the fourth largest city in the United States — firmly in the top 100 largest cities in the world. I’m not out in the wilderness dealing with a country doctor.

I understand HIPAA and other legal and regulatory concerns probably inhibit them from taking e-mail, but other doctors and health care providers have apparently figured it out. But it turns out that the more regulations are involved in something, the more behind-the-times it is likely to be.

It’s RAID. With Floppy Drives.

June 30, 2022 by 38 Comments

There are some tings that should be possible, so just have to be tried. [Action Retro] has a great video showing just such an escapade, the creation of a large RAID 0 array using a pile of USB floppy drives. Yes, taking one of the smallest and most unreliable pieces of data storage media and combining a load of them together such that all the data is lost if just one of them fails.

Surprisingly the process of creation is quicker and simplier than we expected, with a slightly long-in-the-tooth version of Mac OS X making short work of the process. Starting with 30 USB floppies and a pair of large USB hubs, he whittled the pile down to 13 drives that would play nicely and RAID together. The sight of so many drives all lighting up together as the precious megabytes are filled with data is probably not one seen outside the realm of floppy duplication machines, which brings back bad memories for those of us in the consumer software business in years past.

Would you do this? Probably, but should you do it? Of course not, but then again he’s done it so the rest of us don’t have to. Here in 2022 maybe there are better uses for a brace of floppy drives. Continue reading “It’s RAID. With Floppy Drives.” →

PDP-11/34 Restoration And The Virtue Of Persistence

March 28, 2022 by 12 Comments

The wildly successful PDP-11 minicomputer was a major influence on the evolution of computing throughout the 1970s. While fondly remembered in modern day emulation, there’s nothing like booting up the real thing, as [Jerry Walker] explores in his video series on restoring a PDP-11/34. Examples of PDP-11 hardware are becoming increasingly rare, which makes restoration and preservation of remaining equipment even more critical. [Jerry] has gone to exhaustive lengths to restore his PDP-11/34 to working condition, painstakingly troubleshooting wire-wrapped backplane and replacing suspect ICs across the entire system. With scant documentation on some of the cards, it was often a matter of sheer will and technical know-how that saw the system eventually come back to life.

If you’ve got a couple of hours, make sure to check out the entire series of videos documentation the restoration over on YouTube. If you’ve ever thought about restoring vintage computers, this series offers an insight into the satisfying yet oh-so-tedious process of chasing down broken traces and faulty logic. Exorcising the demons from decades-old computers is almost never straightforward, but [Jerry] demonstrates that persistence can yield exciting results. After the break is the latest installment of this series, which shows the system booting into the RT-11 operating system from floppy disk.

If you don’t have the time or real estate to restore a real PDP-11, you might want to check out modern hassle-free replicas. Or, if we’ve piqued your interest in restoring minicomputers, don’t miss what we had to say about previous PDP-11 resurrections, like this PDP-11/04.
