My interface is different from all those in circulation, because it only uses 3 chips and not 4 like all ! Two versions were made, the first (V.1.0) with the horizontal connector and in 2021 the version (V.2.0) with the 90 degree connector, completed by the 3D printed shell.
Description: SCART Interface V.1.0
This interface allows you to connect your European TI-99 / 4A to the TV via the scart. Once the TI-99 / 4A is connected to the TV and turned on, video switching is automatic, the audio output is stereo, as well as the ability to connect to an external amplifier.

This interface allows you to connect your European TI-99 / 4A to the TV via the scart. Once the TI-99 / 4A is connected to the TV and turned on, video switching is automatic, the audio output is stereo, as well as the ability to connect to an external amplifier. The difference compared to version V.1.0 is the complete compatibility with LCD TVs, in addition to the drastic reduction in price.
