Re: QLiberator v3.43

Would be interesting to hear Martin, if his de-compiler seems to change "SELECT ON" things to "ON...GOTO". No it does not. Qlib is the only program I have come across that uses ON..GOTO. I remember having to figure out how it worked, and wondered why it had been used instead of ...

Re: Speedscreen

I have now got the config program to run through the decompiler without errors. It needs some tidying up, but I have had a look at the checking for the master bit. It looks for MDV1_CONFIG_TASK, even if it says otherwise on the screen. I think It tries to do an OPEN_NEW In Qemulator flp1_ and mdv1_ ...

Re: Speedscreen

I had a look at the config program yesterday afternoon, I've updated some of the decompiler library files, but not yet got an error free decompile out of it. But I noticed the bit about placing the original in flp1_. It's followed by a couple of Procedure calls, I think the first one is just waiting...

Re: Microdrive Formatting Failures/Observation

I don't know if it would be of any help, but my MDI driver http://www.dilwyn.me.uk/utils/MDIdriver108.zip has a SuperBASIC program to read raw sectors from a cartridge, and store them in memory. You could try to read a cartridge that has failed to format, and see what if anything can be read from it...

Re: Speedscreen

I don't think I have Speedscreen, Only Lighting. I've just downloaded the Speedscreen demo form Dilwyn's site, but it doe's not look like there is a config file there. If you want me to try to find what the decompiler is having problems with, I would need a copy of the config program.

Re: Speedscreen

Is the configuration program compiled SuperBASIC? if so you could try to decompile it and work out why it does not think it is the master disk.

Re: QL Art

It looks like mdv1_ is in the commands at the bottom, but there is no cartridge in the mdv1_ slot.

The screen display looks like some kind of a demo is running. Could this actually be the PC Four Archive running. As I think that had the TSL language built in, like Xchange.

Re: Help with Composite out

Interference when using the Microdrives is not unusual. The metal plate fitted to the back of MDV1 is supposed to help reduce it. But I always saw some interference when using a TV.

Is this a QL text editor, or a Windows one. If it's a Windows one, it might not have the correct line termination of just a Line Feed.
