  • Hi,

    I have installed Mk3 and after initial confusion and disappointing results it works great:)!. Peace of advice for all: flash latest firmware, it made huge quality improvements for me. Also, after choosing one VGA mode for all and a little bit of fiddling between live configs and a tool to save them I am happy as a pup;).

    However, I have removed my RF module and used this spot to install monitor connection. I had to trim a PCB a little but outcome is AWESOME! I think that you should consider making it a bit narrower and a little bit reshaped to make it an easy job for everyone. (I am using space beneath FDD for my CF card adapter to be accessible w/o opening the case)

  • The adapter-PCB must be fully symmetrical, so both outputs can be used, and the PCB is pushed equally strong in it's place by the lower shield of the A1200 when mounted in the recommended spot.


    That said, please post a picture or two of your modification, so others have an idea of the amount of work that needs to be done. I previously made the suggestion in the German part of this forum to use the adapter PCB upside-down (solder side up) in place of the modulator, so it automatically avoids many parts.

  • All it took was filing PCB to be narrower and fit in place and small cut on the shield and housing to accommodate screws of VGA port. If I put it upside might be even easier. Symmetrical design if PCB is VGA port width would work perfect. I have put insulation between PCB and Amiga motherboard.

  • I guess the approach "solder side up" is a better one. This does not only look like it needs some "cleaning up", but it will most likely always remain at an angle, even pushing against one of the electrolytic capacitors.

  • When I grab some time I will tidy it up (trim a bit more if needed). I will try solder side up too. I am looking to get new case which has VGA hole instead of modulator. In any case If PCB is width of VGA connector it would be easy fit.

    Yes, I mounted it briefly solder-side up with the 4-letter port sticking out the RF modulator hole. Fits absolutely beautifully - had it not been for the VGA connector resting right against the caps behind it. Since I did not like the way the insertion force could/would push on the caps I decided not to mount it there for the moment.
