Re: Pyramide Software - Some Freeware

I have been trying again to get Tridim to run in QPC2. I can get the Manipulation program to run. But I am having problems with the main Tridim program. Tridim crashes at odd places, and does not usually finish starting itself up by drawing the menus. I have a couple of questions I was wondering if ...

Re: PSU alternative?

The PSU http://www.dilwyn.me.uk/docs/hardware/QLperip.zip shows the 16 AC as a separate winding with one end connected to the 0v (GND) line. If as Silverter says, there is an error in the service manual circuit, So that the + and - 12 volt circuit would make sense. Then the AC signal arriving at the...

Re: PSU alternative?

I was looking at the circuit diagrams of the +/- 12 volt supply on the QL and the PSU trying to figure out how they work. The PSU circuit states that it's a 16v AC winding on the transformer. On the QL circuit the +/- 12 volt regulators use the 9 volt DC line as a ground/reference? You can get plus ...

Re: PSU alternative?

As I said above, you would need two transformers. One with a 15V secondary On the contrary, the service manual says: " supplies 9 volts d.c. at 2 amps and 44 volts peak-to-peak a.c. to the board input on connector ". Is this a mistake (or a big misunderstanding of mine)? 44 volts peak to ...

Re: QL not working

The RGB pinout is shown in the service guide. It's been a while since I owned one of these, but the splash screen starts first, with the F1 / F2 prompt, and if you don't hit any keys for about 30 seconds, the screen will default to TV mode - a blue screen and pink cursor. The left hand Microdrive w...

Re: Pyramide Software - Some Freeware

Hi Martin, that sounds like someone has hard coded the screen base address to me! Cheers, Norm. If you are referring to the QPC2 problem. It may have something to do with it. Although I ran QPC2 in 512x256 QL colour mode, so the screen address should have been in the right place. But I do have corr...

Re: Pyramide Software - Some Freeware

I have just done some experimenting with Tridim on Qemulator, and I have found that if I run Tridim in 128K memory mode, the program draws OK. But in 384K memory mode it draws corrupted.

Also in 128K mode, you don't seem to have to wait the 20 seconds for the menu items to appear.

Re: Pyramide Software - Some Freeware

I'm going for a release of Tridim, it contains the following.. English and French versions of the program as Qemulator mdv and Floppy disk images. The Floppy disk images have been patched to use FLP rather than MDV. English and French user manuals in LibreOffice and PDF formats. The English manual h...

Re: Pyramide Software - Some Freeware

Another update. Image9.png Image10.png Image11.png I have attached an English translation of the program, and a user manual. Both are still a work in progress. So don't take them as finals. I have only translated the Boot programs and the main Tridim_exe so far, So let me know if you find any bits o...
