This could have gone to the interesting and funny stuffs topic. Because it is interesting. |

Here's another similar design: https://zxjim.blogspot.com/2011_06_01_archive.html?m=1 |

Just a brand new test popped up.
It was REALLY much faster than the tape or the 1541. I suppose the loading speed is equal to a 10x fastloader on 1541.

Well, I guess that these adapters are still technically limited to the Datassette bitrate, they cannot be faster than that, except for any fastloader mechanisms.
Anyway I have replicated both of these adapters. They are totally untested, but if anyone wants to have a go, I can provide gerbers, etc.
(I guess you'd still need the TAP file for the cassette loader, or you can use them anyway with any audio source on your own.) |

@SukkoPera
Again, you surprised us all 
Two comments:
1) On ZX Spectrum there is a similar project, you can use eg. iPhone to load any program literally for seconds, with a special tool compressing the TAP files.
2) And yes, the method used to "turbo-tape" a program should be available here, but with a better quality and more stable source (no flutter, no wow, higher signal/noise ratio) the loading speed could be much higher.
(here I want to mention the sinclair QL microdive could load files with 10-15 KB/sec speed
"Unfortunately" right now I am in so many differnet projects, I cannot offer any testing. Not to mention my non-existing skills |

Well, you shouldn't be surprised, by now everyone should be aware that I care for preservation!
Of course the easiest thing to do would be to convert those games to TAP and use a Tapuino to load them, but reconstructing old HW is fascinating to me.
The second project I linked is credited to "ZXJim", so it could be the same guy who made the Spectrum adapter.
Anyway, I might throw these into the next PCB order, as usual, if anyone wants to help with the testing, just say so . |
