This is generally a system-agnostic question, as I'm trying to build a feel for my world, and I can add to it whatever rules I need to later.

The world is a 1930s setting, very pulp/noir/steampunk-ish, but with magic in the mainstream, replacing and augmenting technology wherever possible. Things like blackpowder and electricity are considered a form of alchemy.

Eberron's lightning rail is a good example of this.

But I'm terrible at history, and I'm wondering what "modern" technologies existed in 1930. I've got:

  • cars
  • airplanes
  • trains
  • telegraph/telephone?
  • ships

and that's where I kindof stop. :( I want this list to describe "modern" technology right before the advent of computing (including calculators) and wide-spread use of appliances (I don't need a magic toasters, washingmachines, or vacuums).

Please help me (A) fill out/correct this list, and (B) are there any systems or settings which describe something similar? (Besides DnD's Eberron)

Thanks,

Because answers rely on historical rather than RPG expertise, this question is off-topic. (Additionally the request for systems and settings is off-topic as a game recommendation question.) A request for procedures and learning re: magipunk translation of period tech could be on topic, but that is not what this question asks for (despite the title). – BESW Jan 10 at 8:15

1930

Air Transport: Not much civil aviation. but rapidly growing; the 1932 DC3 will revolutionize air travel. Military aviation branching into three fields: Bombers, Transports, and Fighters; scout planes also used. Airships (Zeppelins, mostly) provide commercial long distance air travel.

Cars: Stock cars tended to peak at about 50 MPH. Most were still open wheel, many open cockpit, but that was changing rapidly. Horseless carriages, however, where pretty much gone. The interstate system is still 25 years off, tho' it's being pushed for. The US Numbered Highways system is young. Most urban roads not yet cement nor asphalt; fit stone and brick typical. Unpaved roads quite common
http://en.wikipedia.org/wiki/U.S._Highway has list of the 1925 US numbered highways.

Telephones: Direct dial not yet implemented in most areas, but rapidly being adopted. No long-distance networks for home phones in most areas, and where implemented, not universal access. Typical call involved picking up handset, cranking the handle to get the operator, requesting switch and line, and waiting for the switch operator(s) to connect you. Candlestick phones starting to fall from use. Households typically did not have phones; most calls were business to business, or payphone to business. Payphones existed in many neighborhoods; where direct dial not implemented, the operator had to listen for the coin tones. Phone booths becoming fairly standard in cities.

Special dedicated phone systems called Police Call boxes in use in many major cities. Often, they have a direct line to an operator, and a light for officers to know to call in.

Computers & Electronic Logic: Mechanical tabulators used in some industrial and government applications. A general purpose programmable computer designed but not implemented. In short, a missed opportunity due to lack of foresight. Dedicated mechanical computers being built into warships for fire solutions.

The earliest semiconductors are being developed; 1925 sees the first semiconducting Transistor patented in Canada.

Most electronic logic functions use vacuum tubes. The standard tubes being the diode (one way flow) of 1904, triode (source, output and grid/control leads - the amount of power to the control determines the fraction of the source flowing to the output), and Tetrode (which is a more stable gate than a triode). Fuses and mechanical relays were also in use in some cases.

While the technology was in fact sufficient to build many more complex circuits, including radio squelch circuits and electronic calculators, actual design of these was still a decade or more away.

Telegraphy: Mostly hand-keyed, still, but moving to strip-output. Teletype also in use, uppercase and a few symbols, 5-bit ITA-1 Modified Baudot code used, often printing to strips. (A telegram often would be teletyped, then the strips glued onto the telegram pad.) ITA-2 code was just being released in 1930. All transmissions in uppercase. Radiotelegraphy and radioteletype both known and in military use. Early facsimile transmissions for news wire photographs. In 1930, 3 designs in competition.

Audio Recording: Wire-recording known, but expensive. It's heyday was 1940-1945 (after which, tape replaced it). Direct to disk cutting of phonographs typical; phonographs mostly discs, not cylinders. Audio tape about to be invented in Germany. Optical encoding of sound on film developed; sound quality poor, but easily edited. Radio extremely common for entertainment; serials on phonograph disk pretty much the norm for national programs. Local production of radioplays from scripts also fairly common.

Video Recording: Almost exclusively on film, tho' television could have been recorded on wire. Television known, but not common, in the cities. Sets large, screens small (10+ cu ft for a 5" screen), monocrome, and usually live broadcasts. Films in theaters, often dual use with both stage and screen. Most had an organ or piano, as well, for accompanying the silent films, and many also had an amplified phonograph for playing the accompaniment discs.

Printing: Short runs (<500 copies) typically done using mimeographs (ink forced through a cut stencil onto paper) or the relatively new spirit duplicator, aka ditto machine (wax-ink on back of a master partially disolved by an alcohol solvent and physically deposited on the target page). Optical transcription for mimeographs known but rare, and possible but not documented for ditto.

Offset printing fairly standard for long runs, as is intaglio printing.

Dime novels common, in the now standard pocket format. Comics are often sci-fi or action oriented; some pretty brutal. Many news magazines.

Film & Photo: Talking pictures available, silent films still being made, but no longer drawing large crowds.

Color photography using several different methods possible; the two commonly available in 1930 were tripack film (3 layers of film, each sensitized to one color), and bipack (which was good for flesh colors, but not full spectrum). A third, the screen method, involved a filter with 72 colored (Red, Green, Blue) stripes to the inch, and rendered by a similar color overlay on the resulting B&W film. Also, 3-camera processes also used. If you see early color films, the three camera process was the standard in Hollywood well into the 50's.

Kodachrome is still 6 years off... so decent color cinema also 5 years off.

Color offset printing works best from the three-camera (or 3-strip) process.

Early color cinematography using three-strip negatives was being experimented with, but was not very successful.

Trains: Most trains are steam reciprocating engines, still. Some steam turbine engines developed, but not common use. Electric rail used in some systems, and some turbine-electric engines used. Diesel-Electric still 5 years off.

Boats: Some coal-fired boilers still in use; most commercial now using oil-fired boilers. Turbine-Electric possible, but not typically used. Metal hulls common; smaller boats often wood hulled. This is the heyday of liners for transport. (In 20 years, transatlantic air travel collapses the industry, resulting in cruise lines replacing travel lines.)

Portable Power Sources: small loads, especially portable radios and flashlights, use disposable batteries. Rechargeable batteries in use have a high tendency to be lead-acid batteries, exemplified by automotive batteries.

Large loads generally are produced either by gasoline engine dynamos (DC) or alternators (AC).

Field Radio: the first man-pack field radios are in development. Police radio-cars have receivers only; they still use the call-boxes &/or payphones to call the station. Most commercial boats rely upon field radios; most military battalion and higher HQ's have portable radio transceivers. Almost all field radios powered by batteries.

Home Radio: By 1925, mains powered radio receivers were available. Tetrode radios were replacing Neutrodyne triode radios, as well, resulting in much cleaner radio signals. Most household radios are still battery powered, but not for long.

Word Processing: The manual typewriter with inked ribbon is the norm. Correction typically by erasure. Carbon paper common.

Most documents hand written.

Forms common; local forms often mimeographed. City and state forms often bound offset-printing; a carbon sheet needed for duplicates. Some forms use up to 8 sheets, requiring heavy pressure. Ball-end nibs can be used on carbon forms, but produce a blotchy top copy; pencils used frequently. Typically, carbon using forms typed, then the individual copies hand-signed.

Pens almost exclusively fountain pens. Various nib types, including a ball-end nib, commonly available.

Pencils include the standard wooden pencil (with or without eraser), carpenter's pencils, and the lead-holder (now typically considered a drafting tool). Some early screw-type mechanical pencils also used.

Photocopies: called photostats, they are literally a photograph of a document. Special notaries offered notarized photostats, doing the developing themselves to maintain chain of custody until bound and notarized.

Electricity: Typically AC, and only in urban areas. Gaslight replaced with electric lamps. Rural areas usually still using kerosene lanterns and candles. Electricity mostly used for lights, radios, and motor-appliances (especially washing wringers and agitators in washtubs).

The electric refrigerator is often commercially used, but only just becoming common in houses. Frozen foods rare. It's replacing the icebox (which placed a block of ice above an insulated chest).

Cooking: a variety of types of oven and range top exist.

Urban users tend to gas ovens burning natural gas and/or propane, and similar stove-tops. Electric stoves and ovens exist; they are just starting to make it into homes.

In rural areas, and poorer urban ones, wood and coal are used in iron stoves for cooking; some had oven compartments; if no oven compartment, a large lidded cookpot of cast iron, called a "Dutch Oven" was used. This author has personally seen a 1' deep, 2' wide, 3' long dutch oven used at camping events to bake turkeys...

Fine cookware is usually cast iron and/or copper. Tin and steel is also used.

Motorized electric mixers are available, as are blenders. Few foods are frozen; refrigeration is common, but not universal.

Buildings: the steel-frame stone-facade skyscraper is known. Elevators are available, but only common in tall (5+ stories) buildings. Handicapped accessibility is practically non-extant.

Medicine: Limited antibiotics, limited anesthesia, limited valid pharmacology. Surgery is common, and survivable. Germ theory well known. The flu still kills; polio is deadly. Sexual diseases known and preventable, but most not treatable.

What this all means for Magitech

To replicate with magic, locomotion will be essentially unchanged on the ground, save for how the power is generated. If cheap enough, magic heating for steam engines will be commonplace. If movement magics are cheap enough, the whole engine will cease to exist.

Airships will be more like naval vessels if magic exists which can lift them; otherwise, magic motors on zeppelins will result in indefinite range...

Cars will probably be much more evolved; horseless carriages will have been developed earlier, and aside from a lack of engine, the development is likely to be about 50-100 years ahead, simply due to lack of powerplant constraints.

Electricity can be replaced with stand-alone magic items, IF magic is cheap enough. If electricity can be reliably produced via magic in units the same size as dry cell batteries, most electronics will be magically powered. If magic can produce steady mechanical force, then portable dynamos will replace many battery applications. (Remembering that AC was chosen because of lower transmission losses; most actual uses of electricity are best with DC.)

Radio and TV may or may not be replaced by magic items, depending upon how magic transmissions happen. Films, however, are likely to still exist unless image recording magics are common and tamper-proof.

If illusions are photographable, expect modern level SFX in B&W movies.

Written communication is likely to still be pretty much the same, save that automatic transcription is likely to be much better than real 1930's...

Medicine will likely be about the same point, or perhaps worse. With healing magics, many diseases will be treated by magic instead of medicine, and most physical ailments as well, at least for those who can afford it.

Thanks! It doesn't hurt that my BA was in history... – aramis May 25 '11 at 0:24

To me, it is more interesting to imagine how magic makes technology better. For instance how much faster would a train be if the boiler was magically reinforced?

Also, this question relies on how ubiquitous magic is. If magic is common, then nearly every item can be enhanced by magic. Otherwise, magically enhanced technology would be the domain of the rich.

Also, things like using hydrogen for a blimp would not be necessary, if you could use magically lighter materials. Therefore the hindenberg doesn't happen, and airships would still be a reasonable means of travel.

Magical communication would revolutionize empire building and guerilla warfare.

Magically assisted transportation would revolutionize the speed of commerce.

Also interesting, the failure modes behind the same technologies. In the first World War, soldiers would creep behind enemy lines to snip telegraph wires.

Since Zeppelins are probably powered by magic, a clever spy could use a ring of flight and a Dispel Magic scroll to blow one out of the sky.

Instead of every engineer walking around with a calculator, or a slide rule, it might be a token of divination.

Thematically, the 1800's use a lot of satin, brass, glass, and coal. For you, you might want to focus more on petrol, rubber, and aluminum. just different kinds of smells and textures. Think of very magic device incorporating at least one of these.

Wikipedia is pretty good for this sort of thing. In their article on the 1930s, there's a subsection specifically devoted to technology which lists of of the advances of that decade. Changing the year in the URL easily gives us the 1920s, 1910s, etc.. Granted some of the tech they list is more mundane than you're interested in (e.g. toasters, zippers) but some of it is a bit greater in scale (e.g. radar, nuclear fission).

I didn't even think of that... wow. Thanks! – Stephen Furlani Jan 21 '11 at 20:52

Have a look at Phillip Pullman's His Dark Materials he has an alternative modern history with some good names for modern technologies.
