Video quality revisit
Hi, A few months ago I posted about my dragon behaving poorly with a cheap composite to hdmi converter. I eventually switched out the converter for a different one after testing the machine with a TV that had proper composite in, moved on to sorting out other bits of the machine. The new adapter was...

Adapting PC Joystick
Hi all, I've been working on converting a PC joystick to work with the Dragon, having picked up an old Quickshot Skyhawk with a 15 pin connector for very little on ebay. I've now got it working, but given that I didn't find much info on this when I googled before I thought I'd outline the steps here...

Re: Dragon 32 jumping to buff mode spontaneously?
I'd be interested to see how the Retrotink works out. In the meantime I now have a proper green screen but a couple of annoyances remian. The colours are a little washed out I'm getting some 'bleed through' of the image to the right of the centreas well as occasional very short flickers. Would it be...

Re: New Member, long time Dragon 32 owner
Regarding means to load software, you can take a look at the CASduino if you want to load tape images, or the DragonMMC, CoCoSDC or Drivewire, if you want to load tape/disk/rom images, either from a SD card or from a modern computer. Out of interest which of DragonMMC, CoCoSDC and Drivewire would p...

Re: Dragon 32 jumping to buff mode spontaneously?
I'm now somewhat convinced that this is an analogue side issue. I've managed to test the unit on a different screen with built in composite (previously I was using a composite to HDMI adapter). This has stayed 'green' for a good half an hour. My guess is the adapter, being a cheapy, is being a bit m...

Re: Dragon 32 jumping to buff mode spontaneously?
Thanks for the hint, I'll take a look. I think this is a rev 2 board, so there's a pot by the power header, but that looks to be the only one. I guess there may be a recap in my future then.

Re: Dragon 32 jumping to buff mode spontaneously?
One further development, holding reset for a few seconds then releasing has got it to show as normal for at least a little while, before flockering and jumping back to 'orange'.

Re: Dragon 32 jumping to buff mode spontaneously?
Leaving it sat, powered off on the bench for a bit has got it to life again! Pictures attached. The fuzziness is the composite to HDMI adapter I'm using I think, though I'm getting occasional flickers I don't get with other input devices. The attached images show the screen on power up and a quick b...

Re: Dragon 32 jumping to buff mode spontaneously?
Predictably thus far today it refuses to display anything, though I hear the tape relay clicking. MOTORON/MOTOROFF doesn't seem to be doing anything while it's not displaying. I haven't seen random characters on the display that machines with bad RAM manifest, though the first time I got a picture o...

Re: Dragon 32 jumping to buff mode spontaneously?
Thanks for the reply. I'd somewhat assumed this was not a problem at the analogue output end of things because the 'buff' palette matched buff mode so closely. I guess my main question is if it's worth getting hold of a new VDG and/or SAM and trying them? The SAM's socketted so is an easy swap, but ...
