No breaking news : - The new seal for red tube is curing (need one week for full curing), that was not easy to free the tube from the housing... but I won.   - And a good thing : the tubes mount well with the HT lead downside, so I can fit this set of 120MHz video amps  Robin |

Things going well on Barco n°2 : Red tube is back, and the new video amps works well too. And scheimpflug support mounted.  Robin |

Finally got my J20 mod on the older controller working : after some checks, it was not outputing one of the signals, because I missed a connection on the SN74AC74 and left the "/Set" input pin unconnected... (should be on Vcc)   So it works well with the 808S SEMU, but is still incompatible with the 909 SEMU, I don't get what's different. At least with the controller, I don't have anymore the PLL issue and can work at 45+KHz H frequencies. Robin |

If so and its not working then perhaps it has something to do with the controller as it did not originally have the j20 connector so perhaps its not the same as one that does. |

Hello,
Yes I did, I even used the EPROM from the fully functionnal controller, and it's still the same.
I tried having a look with a logic analyzer the SEMU<->Controller parallel communication, but that's pure binary, not human-friendly at all ; I won't be able the dig this way.
Something else is different from these generations of controllers..
Robin

Yep, I fully agree, but they are rare and struggle to find one !
(and the second SEMU 909-Style too, anyway)
