Display controller first test run. Proof of the ability to control all functions of the display.
Display controller "all options" test run:
•
Switching between two Kernals (SX-64 and JiffyDOS).
•
Switching between two drive numbers (8 and 9).
•
Test of the Reset functions.
•
Test of the volume control.
•
Test of the display control functions.
The Firmware of the Display-Set ( JD567M03 (Board) / AT056TN52 (Display)) must be patched to activate the S-Video input. In order to do this is it necessary to reprogram the MX25L4006E chip on the display PCB with the attached firmware.
However even with the regular Composite Video input of the TFT-Display-Set is the picture quality much better than the original CRT-Display of the SX-64.
TFT and amplifier power consumption test.
Measurement of the power consumption of a replacement amplifier and the TFT Display. The power consumption stays always way below 0.5 amps. The original CRT display with the build in amplifier and speaker consumes up to 1.1 amps.
Speaker and Amplifier test run.
The final speaker, pre-amplifier and amplifier combination.

All necessary information and data to make the SX-64 modification as shown here are included down below in the downloadable "Project Files".
This page presents a modification for the Commodore SX-64 that makes it possible to replace the poor quality CRT monitor with a modern TFT monitor with a really sharp picture.
Originally this page was only meant to present the controller board for the SX-64 TFT conversion. Over the course of time, however, the site has somehow become the main point of entry for those interested in the TFT conversion. Therefore, the focus has now shifted more to collecting, bundling and preparing all the information and data necessary for the modification.
The whole project began when AREA51HD, a member of the German Retro-Computer Board Forum64.de, started tinker around with a TFT display. Through his reports in the forum, more members jumped on the topic and over time this mod has evolved.
It now contains an Extended Reset Circuit as well as a Kernal and Drive ID Switch in addition to the TFT Conversion. Optionally, an improved sound module can be installed.
