Re: MDV Software Reclamation

I saw that with regard to the pointer to int. I can't remember why on earth I had to do that but Digital C was a weird beast if I recall. So the rand function needs to return a long integer and it seems that's how Digital C handled it. It's an implementation of Small C and I do have James Hendrix's ...

MDV Software Reclamation

So I wrote a few pieces of software back in the early 90's. Some personal and some professional. The professional was really for the Apple Mac market but I didn't have a Mac at the time so I wrote it specifically on the QL using Digital C's compiler and then later ported it to the Mac (it was actual...

MDV Dump

I've been reclaiming some documents, software. and SB & C source code from old MDV's and after re-felting they still seem to have an occasional bad sector. I was able to use mdvedit (or is it opdedit?), which I found in the In_Out_Kit_v1_05, to go through sector-by-sector on the MDV and reclaim ...

Re: Q68 Crashes

Can you clarify two things: a) how long is longish and b) what were you specifically running (i.e. which interface and were you running something you created or did it just freeze up on its own)? I've had mine up for hours with no issues (bought it a few months ago) but only poking around the variou...

Re: RGB to VGA

It's just that on the QL, it's absolutely easy, as it only has max 8 colours (That is, R,G, and B are either on or off). On computers like the Spectrum that have an additional brightness signal that you need to mix into the R.G, and B signal, it is a tad more complicated. Tobias Thank you Tobias, t...

Re: Random QL glitch: no video signal and refuses to boot

If putting it back to BBQL doesn't fix it then yes, replacing chips is the easiest. You could put a volt meter on to see if signals are flowing but that requires a bit of knowledge of which pin on which chip wants what -- not impossible but you have to read the circuit diagram for the motherboard an...

Re: RGB to VGA

I haven't heard anyone on this forum who uses that above SCART-to-HDMI also need to create an analog RFB signal. Adrian is pretty technically savvy so I doubt he screwed something up. Are we sure the QL RGB is digital? Edit: this was the video: https://www.youtube.com/watch?v=HpfrelhokKQ You do. Wh...

Re: RGB to VGA

QL outputs RGB in digital form, the VGA signal is specified for an analog voltage which allows a lot more colours - at the very least the QL signals need to be attenuated to hit the levels for RGB So I was watching Adrian Black (Digital Basement youtuber) play with the SCART-to-HDMI converter (the ...

Re: Q68 Serial devices

Derek,

I offered $6 per unit for two and the shipping went from $10.10 to $10.72 so they will give discount if you buy more...in case you choose to stock up and maybe give an option for the Q68 for those that want to use USB. I will post here how well it works once I received them.

Re: Random QL glitch: no video signal and refuses to boot

I have not yet opened my QL (lack of time). But sure, the first thing I will try will be to check the socketed chips. Hopefully it will be just that. I will let you know. François Have you had any luck fixing yours. It's been almost 2 weeks and mine hasn't glitched since so the deduction that futzi...
