It seems you can use an Olympus digital voice recorder in place of a cassette recorder for data storage on old computer systems.

Hey this works with a normal mono microcassettes..
Hi,
When you record with the digital voice recorder, do you use MP3 or WMA ?
I have the Olympus VN-702PC voice recorder and I have been trying to record/load programs for my Sinclair Timex 1000 with no success.
I use low sensitivity recording mode and WMA 32kps
Thank you.
Just found these 2 video gems Julien. And I immediately thought of an application. Record all your accounts passwords and pin numbers in the sharp. Then voice record it onto the Olympus. Save that onto your computer and convert it to mp3 and then a hex file. Get an EEPROM and burn that hex file onto that. Then break of all the pins and put the chip into a small plastic container. Cover the UV window up first. Make a necklace out of the EEPROM and wear it around your neck. Super convenient and ultra secure. Well at least that would have been the way ppl would have secured highly sensitive data in the medieval computer times 😀
Australian, right?
The printer reminds me a lot of my old Game Boy Printer that could print out pictures from the Game Boy Camera and certain other games. It sounds and behaves exactly the same, except the Game Boy Printer started printing a lot quicker.
probably waits a while cause needs to heat up…
Another secret I'll let you in on…a 48 kbit 44,100 hz Mono MP3 file is enough to store a 9,600 baud Group 3 telephone fax. I have a graph_paper.mp3 that I play into the fax machine and can get graph paper on thermal paper whenever I need it.
I commented on a previous video. And that sound is very decodable, i believe i could decode that with ease. It sounds like (well it is) packet data. Commonly used amongst us amateur radio operators.
What and how will it print if we mix up the file in audio mixer software, with some flatulence sounds or other weird sounds?
I think we forget just how atrocious the dynamic and frequency range of cassette tape was – even with expensive hifi decks and brand new chrome tapes it was still p*ss poor, so I'm not really that surprised it works. Be interesting to see if an mp3 would work or whether the psyco-acoustic modelling would just trash the data.
It's great when you start having a moan about a piece of equipment (the thermal printer in this case). Hilarious to listen to. It reminds me of the video you did on the solar power bank.
That would work well for pirating (backing up) a game of Space Invaders on the Commodore 64 datasette.
