Historically rendered 3D maps by Scott Reinhard

Historically rendered 3D maps by Scott Reinhard

I absolutely love maps and visualizations. I’m always on the lookout for cool new creations.

Scott Reinhard combines contemporary land elevations with historic maps to create three-dimensional environments of a specific region, city, or state. To produce the digital maps, he pulls elevation data from the United States Geological Survey, which he then embeds with location information and merges with the original design of the old maps.

Reinhard was introduced to the methods he uses in his digital maps through Daniel Huffman’s website Something About Maps. You can see more of Reinhard’s digital works on Instagram and buy select high-quality prints, on his website.

Attaching 5.25″ floppy drives via USB

Attaching 5.25″ floppy drives via USB

Floppy disks are a relic of the past these days. You can still see the odd 3.5″ floppy – and there are even still companies making 3.5″ USB drives you can plug into your system today. But 5.25″ floppy drives (360k and 1.2 meg variety) are much more scarce. So scarce, in fact, that you’re likely not to find any outside of an old vintage computer. Most modern PC’s since the Pentium don’t even have connectors, interfaces that support them, and I know of no vendors that make USB 5.25″ drives. Even worse, it appears starting in Windows 10, the floppy drivers were removed from the OS.

So what is one to do if they have old 5.25″ floppies they need to read? Turns out others have had the same problem – so you’re not alone.

Here’s some options:

  1. Find a service that will convert them – Usually for a fee around $5-$25 per disk.
  2. Buy an vintage computer from eBay that has a working 5.25″ drive.
    For PC’s, this means a 486 or lower computer. Almost all plug-in floppy controllers require a PC who’s motherboard has an ISA interface (not PCI). You must be careful because older 8-bit ISA floppy controllers (from the XT/AT era) often will NOT work in faster 386/486/Pentium ISA interfaces (even though they are supposed too and early 486 motherboards let you slow down the ISA interface clocks in BIOS). Vintage Apple, Commodore 64, and other computers can be found on local sales forums, ebay, garage sales, and swap meets. You can then potentially copy the data off and transfer to a modern computer using a network or a serial port transfer cable.
  3. Use a flux-style reader. These allow you to attach a 5.25″ drive to a controller board which then connects to your USB port. The big limitation is that you cannot interact with the disks via DOS or command line options. Instead, you need to read/write whole disk images or operate at the sector level. These readers do this by reading flux data. While this is more complicated, it is the method that archivists are using to backup disks. Reading flux data gives you the ability to read/write disks from almost any platform and in any format – even copy protected disks.
    1. GreaseWeasle V4 [NEW 2022]https://decromancer.ca/greaseweazle/
      Interfaces with 8″, 5 1/4″, and 3 1/2″ drives. Amazingly, it only costs $31 CAD and seems to get as good reviews as the Kryoflux. Definitely one of the cheapest options on this list. Since it extracts the raw flux transitions from the drive, any diskette format can be captured and analyzed – PC, Amiga, Amstrad, PDP-11, and just about any other computers as well as many older electronic musical instruments and industrial equipment floppies. They also include a wonderful array of disk reading/writing software utilities. The design is fully open and comes with no license encumberment.
      [UPDATE 10-2022] I bought one of these and could not be happier (lots of info here). It’s pretty sweet!
    2. SuperCard Prohttps://www.cbmstuff.com/index.php?route=product/product&product_id=52
      Seems like this is the new high-end champion. Not cheap at $99, but it gets regular firmware updates, can read an amazing array of flux data. Can be driven from a USB port or as a stand alone device. Supports duplicating disks that were written with the data starting and ending at the index pulse (the majority of all commercial programs were created this way). It also supports non-index copied disks and has an analyzer program that allows you to duplicate 100% of everything written on standard circular tracks, regardless of their relation to the index pulse.
    3. Kryoflux https://www.kryoflux.com/
      Used to be the holy grail of floppy readers, but not cheap at 105€. It is able to read all formats, save as a raw stream, or export to common sector formats like the Acorn Electron, Apple, Amstrad CPC, Archimedes, Atari 8-bit, Atari ST, BBC, Commodore 64, Commodore Amiga, MSX, IBM PC, PC-8801, Sam Coupe, Spectrum, E-MU Emulator & Emulator II, DEC RX01 & RX02 and many others.
    4. Device Side Data’s FC5025http://www.deviceside.com/fc5025.html
      USB 5.25″ floppy controller plugs into any computer’s USB port and enables you to attach a 5.25″ floppy drive. Even if your computer has no built-in floppy controller, the FC5025 lets you read those old disks. It also understands formats used by Apple, Atari, Commodore, TI, and others.
    5. Supercard Prohttps://www.cbmstuff.com/
      I don’t know very much about this one, but here’s a review and this page which contains a lot of useful information.
    6. DREM https://www.drem.info/
      DREM is a MFM/RLL hard drive emulator that can read raw dumps of a hard drive. It also allows you to read floppies. More here.

Cables/Adapters for connecting 3.5/5.25/8″ floppy drives to your PC:

Finding cables for your floppy drive can also be a pain. Here are some places you might look, but supplies and suppliers do come and go frequently.

  • CablesOnline http://www.cablesonline.com/ also their (ebay store)
    CablesOnline has a good selection of universal floppy cables for a very reasonable price.
  • IEC.net also has a selection of floppy cables, and can custom-make floppy cables for you.
    • They also have MFM and RLL hard drive cables (and can make them to order)
  • Dbit http://www.dbit.com/fdadap.html
    The DBit FDADAP board is a small adapter which adapts 8″ floppy disk drives (Shugart SA800 style bus) to work with the PC 3.5″/5.25″ floppy disk cable pinout. It has 34- and 50-pin connectors which can be connected to the PC floppy controller and the 8″ disk drive using simple straight-through ribbon cables (not included), and a 3.5″ style power connector for the on-board microcontroller
  • TexElec – https://texelec.com/product/8-inch-floppy-adapter/
    TexElec makes tons of retro computing dream boards (clone Adlib, IDE, floppy, and other controllers) as well as this 34 to 50 pin 8″ floppy drive adapter board that allows you to plug in 8″ floppy disk drives with a standard PC 3.5″/5.25″ floppy disk cable.

Dead/Discontinued controllers

  • Catweasel http://www.nishtek.com/cw.html
    Discontinued PCI board for connecting to floppies. Like other solutions, it doesn’t make drives show up as a drive letter – but rather lets you read raw formats for all sorts of platforms.

Crossing the Sahara in the 14th century

Crossing the Sahara in the 14th century

I have been fascinated with early stories of people trying to climb mountains, have early adventures through vast foreign lands, or cross the great unknown and deserted barrens.

Yet no stretch of land is so isolated, bare, and desolate as the Sahara desert. It’s hard for us to imagine the realities of traveling during the early centuries of modern civilization, but fortunately we have some documents from those periods. Some of which have been summarized and collected in a book called ‘The Golden Rhinoceros: Histories of the African Middle Ages‘, by Francois-Xavier Fauvelle.

First off, there were your guides. You had to travel in groups for safety from bandits and injury. Guides at the journey’s port cities had to be purchased to lead you across the desert. Deserts they knew fairly well because when not guiding, they might be the very raiders that would kill you on a different trip. They were often a shady lot that had little patience for the unprepared.

While today’s travelers complain about $4 bottles of water at the airport, the water situation was different for earlier Saharan travelers:

Then there was the problem of water. It would be even better to say the problem of thirst, your constant companion during the crossing. All travelers, all geographers say the same thing: the water is sometimes “fetid and lethal” and, Yaqut al-Hamawi humorously reckons, “has none of the qualities of water other than being liquid.” Such a beverage inevitably generates intestinal pains that make life difficult and sour the memory of the trans-Saharan experience. In good years, when there had been plenty of rain, water filled the rocky gullies, and people could drink and do laundry. In bad years, the burning wind dried out the water in the goatskins; consequently, a camel’s throat had to be cut and its stomach removed. The water it contained was drawn off into a sump and drunk with a straw. In the worst-case scenario, one could kill an addax antelope and follow a similar procedure to extract greenish water from its entrails.

We complain about uncomfortable airline seats for 8 hours while crossing the ocean at 30,000ft. Earlier travelers endured countless days/weeks of far worse inconveniences.

And then there were the small, but numerous and in the end obnoxious, daily inconveniences: the omnipresent fleas, which you would try to drive away by wearing cords soaked in mercury around your neck; the numerous flies everywhere there was a rotting carcass (i.e., precisely around the wells and the camps); and the snakes.

And then there was the ever present danger of dozing off, lack of attention during a stop, or just getting turning around in the maze of dunes to realizing you were separated and probably lost in the desert to die.

The caravan tempers these harsh conditions with strict discipline; it diminishes them through distractions. You will put distance between yourself and the column only at your own risk, the Berber leader must have said. Those who paid for the crossing would amuse themselves hunting addax, letting their dogs run free, and riding a bit ahead of the caravan to let their horses graze and to enjoy the invigorating wait. But the games, the intemperance of the city-dwellers, could cost them dearly. Even though caravans could be made up of hundreds, sometimes even thousands, of camels, one could quickly lose sight of them behind a curtain of dunes. A few centuries later, on the same stretch of desert, but from the opposite direction, a caravan of pilgrims lost two of its members in a row and yet noticed only a day and a night after they disappeared. Nobody dared go back to look for them for fear of being lost themselves. The author of the story concludes philosophically: “But our conscience was clear because we had warned them of the risks they were running by not abiding by the rules of the caravan.”

Sasha from Pyramiden

Sasha from Pyramiden

Pyramiden, located far above the Arctic Circle on Norway’s Svalbard archipelago, has been all but abandoned since 1998 – with only 6 year-round residents.

Aleksandr Romanovsky, who likes to go by the nickname ‘Sasha from Pyramiden’, has worked as a tour guide at the Russian settlement since 2012 when, he thinks, he was the only person to apply for the job. A loner by nature, Romanovsky has come to feel at home in this unusual, otherworldly place. He spends the time between giving tours and warding off polar bears enjoying solitary pursuits such as playing the guitar and learning Spanish.

Chicken for a pet

Chicken for a pet

We had chickens – and everything they’re experiencing is exactly what we did. Cats being afraid of him, their cannibalistic tendencies, and being a general jerk at times – all were the same for our chickens too.

Love it.

Slowing down the past

Slowing down the past

Hot on the heals of Peter Jackson’s They Shall Not Grow Old, restoration of old films using lots of fascinating new techniques is hitting mainstream. One of those technologies being to slow down the old hand-crank ~10fps movies that play too fast when put on modern ~30fps transfers.

Videographer Guy Jones slows down film from the late 1800s to early 1900s to more accurately match the speed at which modern footage is recorded and played. In addition to editing the pace of the century-old film, Jones also adds in sound effects to make the scenes more relatable.
