Why the hard drive is called C

The hard drive or solid state drive on your PC is called drive c, which implies the existence of a drive A and B. So what are drives A and B? What does the C drive stand for? Why is the hard drive called C?

Drive letters are a holdover from early microcomputers. The letters A and B went to floppy drives, so if you had a hard drive, it went to the earliest available drive letter, which was C.

Radio Shack fire chief’s helmet: a passive aggressive gift

One of my friends asked me about a toy space pistol his son found at a comic book shop that originally came from Radio Shack. I told him what I was able to figure out, and he said it made a pretty annoying noise. And that reminded me of my favorite toy when I was five. It was a Radio Shack fire chief’s helmet with a real working light and real annoying siren.

The Radio Shack electronic fire chief’s helmet boasted of a real rotating light and loud siren. Unfortunately, they forgot to recommend playing with it outside rather than indoors, which is probably why so many of them fell victim to sabotage and are scarce in working condition today.

Bing was a long running German manufacturer of inexpensive tin toys. Like many of its competitors, they were based in Nuremberg, Germany. Founded by two brothers, Adolf and Ignaz Bing, they remained a family owned company from 1863 until their demise in 1933. Originally a maker of kitchen utensils, Bing became a pioneer in what we today call model railroading, creating the standards we today call O gauge and OO scale.

Dorfan: Bleeding edge electric trains

Dorfan Manufacturing Company was a pioneering toy company specializing in electric and clockwork-powered toy trains. Diecast trains at that, which was state of the art when the company started in 1924.

Dorfan was an offshoot of the German toy company Fandor, founded by German immigrants Milton and Julius Forcheimer. They named the company after their mother and their aunt and were headquartered on Jackson Street in Newark, New Jersey, and operated from 1924 to around 1938.

Cyber Kill Chain vs Mitre ATT&CK

The Cyber Kill Chain, developed by Lockheed Martin, and Mitre ATT&CK (pronounced “attack”), are frequently compared, for obvious reasons. Both of them describe how adversaries attack computer networks. So when it comes to Cyber Kill Chain vs Mitre ATT&CK, which is better? It depends who’s asking.

Even the 1980s service manuals for the machine gloss over or omit disassembly. So here’s how to disassemble a Tandy 1000EX, such as to give the case a thorough cleaning.

American Flyer Trainorama backdrop

The question of backdrops, especially for a tinplate layout, is always a difficult question. Lots of commercial backdrops are available today, but modern backdrops often look more appropriate with scale models than with a traditional toy train layout. American Flyer’s Trainorama is a potential solution that works well with prewar and postwar style layouts.

The American Flyer Trainorama was a 3D backdrop, 9 feet long, lithographed on heavy cardstock by Niagra Litho Company. Its catalog number was 790 or 791, and it was only available in 1953. The packaging was a large paper envelope.
