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 mo...

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 RG...

Re: Help with Composite out

Finally question. I've read that it's important to add some sort of protection (zener diode?) to keep zx8301 chip from unwanted monitor feedback (static) as it can blow the chip. I've only ever used RF and I'm guessing that it somehow protects the chip since I've unplugged the rca connector for deca...

Re: Help with Composite out

So I finally did the mod. What I discovered is that color composite is indeed NTSC. What gets confusing is when I use color composite and press F1 for monitor my cheap monitor can't handle the signal, gives me a crappy monochrome picture and says PAL. So Martin was correct, the monitor was just gett...

Re: EasyCircuit v2.01 (German) now Freeware

Tried running the basic program on QLAY2 (I also use QLA2K when I want sound but it kind of messes too much with audio) and got some weird errors: 150 GLOBAL a% Is that a QLiberator thing? 240 Ax$='<<QCFX>>01 This line started with that but was over three lines and had unprintable characters. It als...

Re: QL Case Heat Warp

I have put two small plastic feet, self adhesive, IKEA style, they fit small circular marks on the bottom. Did that help prevent the bending? I'm wondering if I should put some support on the bottom middle of the case so it barely puts some upward pressure on it (maybe barely lifts the left side by...

Re: EasyCircuit v2.01 (German) now Freeware

P.S. I believe it was written in SuperBASIC and then compiled as an exe with SuperCharge. Would be cool to see the actual SuperBASIC program and run it. Compiling probably sped it up but with the faster machines and emulators it would probably run pretty decently form source. Also, how do old execu...

Re: Designing 3-D cases: vDrive & Q68

Here is vDrive design #2. Note that if you aren't that interested in the vDrive (or the modified vDrive that this case is being made for) then these designs and examples may not be that interesting. However, take note that I tried to recreate the QL theme on the lid and I'm learning as I'm going and...

Re: Help with Composite out

I haven't used my BBQLs much with composite colour, but I remember the picture quality was quite poor. Lots of dot crawl and definitely not suitable for a 80x25 screen. On the other hand, the monochrome picture is rock steady. I'm still using my green monochrome Philips monitor of almost 35 years w...
