Re: QL PSU

The AC to DC gives the 15V DC No! The QL needs 15V AC ! Be careful! Sorry about that I forgot even though I measured it myself a month ago. :oops: The AC makes it awkward & expensive these days since small transformers seem to be a thing of the past. The 200 mA current is also high so not such ...

Re: QL PSU

If you want to knock up a PSU you could use an AC to DC module and a DC to DC. The AC to DC gives the 15V DC and the DC to DC gives the 9V the only problem is the connector to the QL. :roll: I was looking at these boards for something else with different voltages but the principal is the same and ch...

Re: How do you make a QL emulator?

Hi Norm I'm not following you here, sorry. QT for example, comes with everything you need for cross platform development in C++, as does wxWidgets. I don't see what you think is missing from the "environments". Ideally I want compile once run on anything not compile for each OS. :) I haven...

Re: How do you make a QL emulator?

Thanks guys it sounds like I shall have to stick to FPC that I prefer and maintain compiled copies for each OS. I prefer FPC to C & C++ . The so called cross platform languages don't sound like much use if they require other environments not standard in the OS or there is the possibility of bein...

Re: How do you make a QL emulator?

Hi Norm From the previous discussions I thought someone would just say Python or Javascript that seemed like the choices. :roll: The app on computer or phone is only going to be used to set parameters on a piece of hardware & start or stop it. I want one app that runs on any platform so there is...

Re: How do you make a QL emulator?

I see from the discussion you guys have used lots of languages. If I wanted to write an app that uses a serial port or wireless and could run on any device what language should you use? The app is not time critical it is just for set up purposes like a remote control and bare in mind I have a brain ...

Re: PCI Express video

I can not imagine any of the QL emulator authors being interested in such a job. I am not asking anybody else to do it I am looking at my options and what I might be able to do. Do you want a different OS to be the base of your machine, so you can emulate in software? Maybe what I require is alread...

PCI Express or Pi zero QL replacement possibly

GAME OVER Would you like to play a different game? I don't like games I like progress. :) At the moment I have a dead QL and looking for an easy alternative to either a fix or replacement. I assume everybody has been through everything I am likely to think of and dissuade me from stupid thoughts bu...

PCI Express video

There has been some discussion of using PCI but what about using a PCI express connector or interface so the internal ram based video can be eliminated and a bottom end PCI video card used instead. The QL CPU could write to a high speed serial line like a one line PCI express connection instead of w...

Re: How do you make a QL emulator?

I've probably written some 100.000+ lines of assembler in my days and I'm quite fed up with it. Me too and a classic example of zero progress. Python is pretty much the new Basic now. Another person reinventing the wheel. Why? Higher level languages should in theory promote a more structured approa...
