Re: Help with Composite out

I should probably post on the general forum for any other US'ers to see what the back of their motherboard looks like. I appreciate your continued feedback on this. I keep learning more and more about analog video, which is kind of crazy across all the standards including composite, component, ega,...

Re: QLiberator decompiler

I am continuing to rename the vars in the new decompiled QLiberator source. Here is a snippet ... 1090 REPeat tokens 1100 IF NEXTLINE THEN 1110 EXIT tokens : REMark NEXTLINE means End Of Program has occurred 1120 END IF The way that NEXTLINE is being used, it appears to return End_of_Program. Being...

Re: Help with Composite out

Unless there is something very different about the video out on the US version of the QL. Someone in the past has made a lot of modifications around the video socket. I suspect they cut the signal from the modulator to the composite video out (because they did not need it) and used the freed up pin ...

Re: QLiberator decompiler

I will have a look into these things. Line 4310, yes that looks like a typo on my part when converting the GO TO's back into REPeat loops Line 16300 must have confused me a bit, as I put that REMark there. It can be quite hard trying to tidy up the decompiled code , identifying REPeat, NEXT's and EX...

Re: QLiberator decompiler

Back to Disk Mate 5. I got a bit side tracked, and forgot that I had not posted the decompiled sources for Disk Mate 5. The zip file contains the original Disk Mate 5.10 source, and my version 5.11 which has the reference to the FileInfo 2 command 'FEX' changed to FI2_CALL. And so need s FileInfo 2,...

Re: Help with Composite out

Now that I"m running off of NTSC color composite, the picture is better than RF. At least some of the artifacts do go away (like most of the shimmering). It still has the shadow effect where, for colors, the image is echoed a millimeter or two to its right (and there is no adjustments on the m...

Re: Microdrive failure after felt pad detaches - ideas?

I know you say that the tape head looks clean. But try cleaning it with a tape head cleaner, or isopropyl alcohol. It may be that some dirt you cannot see is stuck to the head.

Re: Help with Composite out

All those resistors tacked onto the board under the video socket is not normal on a UK QL. It may be that a previous owner has tried to reduce the 5 volt RGB signals to 1 volt signals. Which are required by some monitors or TV's. This is usually done by a couple of resistors in each line in a QL RGB...

Re: Help with Composite out

When I use pin 9 of the MC1377 and ground off of the RGB connector (pin 2) I seem to get a color PAL composite signal (when using the composite connector on the TV, my TV seems to briefly display what type of composite input it gets) that basically looks pretty close (as crappy) to my RF signal -- ...
