There's booting from a floppy and then there's booting from vinyl

So we know it's possible to build records from the pre-microprocessor days so if at any point distributing software for something like (or maybe the OS itself) becomes an issue, it's possible to cover some bases with a 45 RPM 10" record

I'm sure the EPROM can be replaced with hardwired functionality

This specific example has a kernel

@cypnk This used to be more common than you might think.

Back in the 1970's several magazines experimented with this format for distributing software.

@profoundlynerdy Since radio is very old, I wonder what the practical considerations would be of distributing software over AM/FM

I'm guessing noise will be an issue, but if it's taken slow enough, even binary can be sent practically over the span of several minutes to an hour

@cypnk This has been done, too. There was a TV show in the 1980's that had software for the BEEB distributed over audio at the end of the program.

I don't recall the name of the program, but there are YouTube clips. I'll update this thread if I can find it.

But, yeah, you could send data over #shortwave (slowly) via #Morse code if it could be represented as [A-Z] [0-9]. The z-base-32 encoding can do this, I think. I don't think uuencode is up to the task.

@cypnk @profoundlynerdy Right, radio works but just shipping cassette tapes was much cheaper and more reliable. It's not hard to bootstrap up to tapes, and they're useful read/write devices.

@profoundlynerdy @cypnk I mean didn't a lot of old pcs load from tape, even if not using that standard

@a_breakin_glass @cypnk Yes. This was more common in the 1970's than the 1980's and later (in the US). It was quite common in Europe on 8-bit platforms almost into the 1990's.

There were tons of pirated games on fast-loaded cassette tapes for the C64 targeting the European market for example.

@profoundlynerdy @cypnk Also this:

I remember hearing BASIC programs get distributed on the radio and finding the sound unpleasant.

@reinderdijkhuis @cypnk Dude!

Do you know about more of these? I'll let TOSEC know so that it can be properly cataloged.

@cypnk cassette recorders still exist (and are making a resurgence thanks to hipsters, which might prompt re-investment in making higher quality decks - magnetic tape is cheaper to distribute than vinyl, and FM radio can be used to transmit the audio for computer data (this was done by several European public service broadcasters at various times in the 1980s)

@vfrmedia I just had a ridiculous idea that I think should be tried at some point

Public performances of xylophones using frequency-shift keying to "send" software

If the musicians are good enough, it's possible to send E.G. BASIC or some variant of DOS via street performance

@cypnk I know the west german WDR ComputerClub TV show in the 80s had some clever system with the very metal sounding name "hard-bit-rock". It encoded BASIC programs into a couple of scan lines of the video signal. If you had the right filter you could then record them onto your Datasette. Here's a slightly hazy translation about the show:

@praxeology @cypnk

Britain's BBC also used the spare lines in the vertical blanking interval (also used for Teletext) to transmit software, the BBC Micro's Teletext adapter (and other devices) could work with it but none of that hardware was cheap. The technique is still used today for the various digital text /graphics services other than linear TV and radio that are transmitted via digital video broadcasting in Europe..
