humeur Posted November 5, 2020 Share Posted November 5, 2020 Who among you has ever found a sticker where it is rated "CS1 Only" by removing a TI99 / 4a. Qui d'entre vous a déjà trouver un sticker ou il est noté "CS1 Only" en démontant un TI99/4a. Jean louis 1 Quote Link to comment Share on other sites More sharing options...

HOME AUTOMATION Posted November 5, 2020 Share Posted November 5, 2020 If you look at the picture of the QI's board. You might notice that there are only enough driver components for CS1. Oddly, I seem to recall using a QI that supported both CS1 and CS2. Quote Link to comment Share on other sites More sharing options...
Ed in SoDak Posted November 5, 2020 Share Posted November 5, 2020 (edited) Makes me wonder if the user manual for it had CS2 references deleted. Edited November 5, 2020 by Ed in SoDak Quote Link to comment Share on other sites More sharing options...

You might notice that there are only enough driver components for CS1. Oddly, I seem to recall using a QI that supported both CS1 and CS2. If the schematic represents the final product, the QI board lacks the motor control circuitry for CS2 and pins 6 and 7 of the cassette port are not connected. However, the audio output channel is shared between CS1 and CS2 so you were likely able to save to CS2 without motor control. 1 Quote Link to comment Share on other sites More sharing options...
HOME AUTOMATION Posted November 8, 2020 Share Posted November 8, 2020 Come to think of it better ...I was only using CS1. Quote Link to comment Share on other sites More sharing options...
fabrice montupet Posted November 8, 2020 Share Posted November 8, 2020 Bonjour Jean-Louis, Pour pouvoir t'en dire plus, il faudrait une photographie détaillée de la carte mère, au niveau du port K7, pour voir si une modification a été apportée. 1 Quote Link to comment Share on other sites More sharing options...
