Re: [M100] Virtual cassette idea

A while back I had the idea of having an Arduino decode and bit-bang the cassette port protocol on my T102. As with all of my projects I got distracted, never finishef, and ended up using the MIDI cable for its intended purpose. It seems a more efficient way of storing what is honestly a tiny

Re: [M100] Virtual cassette idea

I have to agree that it is possible but in my experience not reliable. Maybe it boils down to the device. I have an mp3 player that I was using and it works sometimes and not others very frustrating. On Sunday, July 30, 2017, John R. Hogerhuis wrote: > > > On Sat, Jul

Re: [M100] Virtual cassette idea

Interesting. That would explain why I am able to use ts-dos.mp3 on my phone, but the volume has to be all the way up. If it is a single step down it doesn't work. And someone else couldn't get it to work at all from their different phone. Also in my case, at first I tried using a stereo-to-mono

Re: [M100] Virtual cassette idea

I think the problem is voltage level from common audio devices is not high enough. Need to have at least 2vpp. Most devices put out max 1. On Friday, July 28, 2017, John R. Hogerhuis wrote: > I think it would be cool. > > You could also do this a smart phone app. > > The

Re: [M100] Virtual cassette idea

I think it would be cool. You could also do this a smart phone app. The cassette file I/o has the advantage of being integrated into the rom. That's why I made CloudT emulator interface with google drive and such via hooked cassette I/o commands. -- John.

I keep messing around with Ted Rossin's circuit & s/w. the website is gone but i saved the files a few times and archive.org has a recent backup of the schematic https://web.archive.org/web/20170302024947/www.tedrossin.net46.net/Electronics/Pic/Schematics/CassetteInt.jpg if the circuit

Re: [M100] Virtual cassette idea

Jeez, storing a huge WAV file for the several hundred encoded bytes reminds me of the cryo-flux approach to backing up floppies vs FC5025 which reads floppies like floppies. How about "encoding" the audio into a file, then playing the saved encoded file back as audio? More work for sure, not

[M100] Virtual cassette idea

I'm running an idea through my head and I'd like to bounce it off you guys. The idea is to create a virtual cassette recorder/player. Possibly for my T102, but also for the pocket computers that I have. I've found this
