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.

It’s Always Floppy Time!

February 9, 2022 by 9 Comments

On [Jan Derogee]’s desk is something that wouldn’t look out of place for many of us, a pile of computer magazines with a case of 3.5″ floppy disks on top of it. The causal observer would see nothing more than the detritus of a retrocomputer enthusiast’s existence, but stick around. In fact it’s a clock, and one of the most unusual ones we’ve seen in a long time.

How can a box of floppies tell us the time? Selected disks have custom labels that look as though they might be authentic game collections, but in reality are fakes that carry numbers alongside the game art. An ingenious system of cams hidden in the hollowed out pile of magazines raises the correct floppies to tell the time, hours on the left row and minutes to the closest five minutes on the right. The floppies are modified by the removal of some plastic and the disk itself, because early versions had a habit of shredding disks. A final touch comes in the form of a Nokia phone on the desk next to the clock which plays a tune in lieu of chimes on the hour. You can see the clock in action in the video below the break.

8″ Floppy On Your PC?

November 10, 2021 by 52 Comments

We should probably have a new metric for measuring mass storage performance: bytes per pound. An old IBM tape drive from the S/360 days, for example, could hold almost 6 megabytes of data. It also weighed more than a typical refrigerator. Today, a tiny postage-stamp-sized card can hold gigabytes of data and weighs — at most — a few ounces. Somewhere in the middle is the old 8 inch floppy drive. At its peak, you could cram about 1.2 megabytes on it, but even with the drive you could lift it all in one hand. These disks and their descendants ruled the computing world for a while. [Adrian asks the question: can you use an 8″ floppy drive on a PC? The answer is in the video below.

He didn’t do it on a lark. [Adrian] is getting ready to restore a TRS-80 Model II so he wanted to create some 8″test floppies. But how do you marry a 40-something-year-old drive to a modern computer? He had a few drives of unknown condition so there was nothing to do but try to get them working.

Arduino Nano Floppy Emulator For When Your Disk Is Not Accessible

October 17, 2021 by 15 Comments

Among the plethora of obsolete removable media there are some which are lamented, but it can be difficult to find those who regret the passing of the floppy disk. These flexible magnetic disks in hard plastic covers were a staple of computing until some time in the early 2000s, and their drives could be found by the crateload in any spares box. But what about today, when there’s a need for a real floppy drive and none is to be found? Enter [Acemi Elektronikci], with an Arduino Nano based floppy emulator, that plugs into the floppy port of a PC old enough to have one, and allows the easy use of virtual floppy disks.

Aside from the Nano it has an SD card and associated level shifter, and an SSD1306 i2c screen. Most of the Arduino’s lines drive the floppy interface, so the five-button control comes to a single ADC pin via a resistor ladder. He freely admits that it’s not a perfect cycle-exact emulator of original hardware and there may be machines or even operating systems that complain when faced with it, but for all that it is a useful tool. One of the machines that may have issues is the Amiga, but fortunately there’s a fix for that with a Raspberry Pi.
