repetto74 Posted September 14, 2017 Share Posted September 14, 2017 I would like to build the cassette deck cable to hook the Ti99/4A to the cassette tape recorder. I have a link to the schematic here : http://mainbyte.com/ti99/hardware/cables/cassette.html so MIC and Speaker will need a 3,5mm MONO audio jack but what about the Remote port ? Which kind of jack do I need for this input? This is smaller than the 3,5mm input. Thanks Rick Quote Link to comment Share on other sites More sharing options...
ti99iuc Posted September 14, 2017 Share Posted September 14, 2017 you probably need for the Polarity Converter Plug to use your tape recorderhttp://www.ti99iuc.it/web/go?AN865T Quote Link to comment Share on other sites More sharing options...
sparkdrummer Posted September 14, 2017 Share Posted September 14, 2017 Yes, the cassette control plug is smaller than an 1/8" one. I would suggest not soldering the leads until you have tested the polarity to make sure it shuts the motor off properly by the computer. One more thing, I have one of the newer GE models that has a stereo jack for the earphone and the computer doesn't like it much. If you're using an older recorder you should be ok.

With stereo jacks always best to use a stereo to mono adapter or splitter and use one side Sent from my LG-H830 using Tapatalk Quote Link to comment Share on other sites More sharing options...
repetto74 Posted September 15, 2017 Author Share Posted September 15, 2017 Hi Guys, The cassette recorder is old yes, dated around beginning of the 80's so it should be fine and ouputs mono only. I will build this cable and test it then to check it is properly working . Thanks Rick Quote Link to comment Share on other sites More sharing options...
repetto74 Posted September 27, 2017 Author Share Posted September 27, 2017 (edited) Hi Guys, Just for you to know, I did built the cable and it is working properly except that the TI99 cannot manage to control the datassette motor so I need to manually record and stop when required :-) Anyway I friend has picked up a couple of days ago a TI99/4A at a local garage sale with the original datassette cable and REM adaptors so he gave them to me .

Saya Posted June 6, 2020 Share Posted June 6, 2020 repeto74: Would it be possible to load the ti994a programs with a smartphone (by reading your wav files) with the original cable? Quote Link to comment Share on other sites More sharing options...
wierd_w Posted June 6, 2020 Share Posted June 6, 2020 (edited) Theoretically possible; Use something like VLC that can blast the headphone jack's volume outside the "Safe for headphones" volume levels, otherwise the TI wont successfully read. Your typical media player observes this safety limit, but in this case, you want it to blow the roof off. (also, the post you are replying to is like, 3 years old?)

Saya Posted June 6, 2020 Share Posted June 6, 2020 (edited) the ti994a tape recorder has components that are connected to the ti994a. CRU bit 22, 23, 24, 25 and 27 which must inform the TI on the link between the two. it would be necessary to recreate a cord with these bits etc ... etc Edited June 6, 2020 by Saya 1 Quote Link to comment Share on other sites More sharing options...
wierd_w Posted June 6, 2020 Share Posted June 6, 2020 Keep in mind that there is an open ground condition on the microphone lead. It can be "ghetto" resolved by bridging the grounds between the speaker and microphone jacks. If you don't sort out that open ground condition, there will be a terrible hum when attempting to get data from your external source (such as your smartphone), and the read will fail.

Saya Posted June 13, 2020 Share Posted June 13, 2020 (edited) I went through an ordinary pair of speakers (hanging around in the garage), put the volume of the smartphone at bottom two notches. set the speaker volume to level 7 'envirion', eeeeeeeeeeeeeeeeeeeeeeeet altavista baby !!!!!!!!!!!!!!!
