Re: Some new W10 devilry

I had this problem https://qlforum.co.uk/viewtopic.php?f=19&t=1916&p=16875&hilit=screen+saver#p16875

Can't remember if this was QPC2 version 3 or version 4. But I just don't use the screen saver any more.

Re: Status of QMON

I've got a English QMONII manual, on pink paper. It's a Digital Precision one, so I don't know if its the same as Olifink's.

On the back page it talks about updates for version 2.06

Just say if you would like it scanned (file type/resolution), or I could try to OCR it.

Re: QPC2 on Second Screen

When I 'upgraded' from a Windows XP PC, to a new windows 10 PC about a year ago. I was getting weird, similar sounding problems with QPC2 after the PC's screen saver came on. I'm pretty sure it was screwing up with QPC2 V3.xx, not sure about QPC2 V4.xx. In the end I just switched the screen saver of...

Re: Possible problem with cloned SGC and Minerva 1.98

Issue 5 QL, with Minerva 1.97, An original Miracle Systems Gold card with ROM version 2.32 Interesting. Do you have any means for reading out the complete 2.32 ROM? If not, can you SBYTES the area $1C200-$1FFFF after boot and send it to me? Cheers, Marcel Here's an SBYTES, 15871 bytes, is that righ...

Re: Possible problem with cloned SGC and Minerva 1.98

I decided to try to replicate your problem. After a lot of trouble of trying to get a QL to work, and find a microdrive cartridge that still worked. Power up, F1, LBYTES mdv2_filename,131072 And I do not see the problem, It works as expected. This is the set up... Issue 5 QL, with Minerva 1.97, An o...

Re: Possible problem with cloned SGC and Minerva 1.98

Another bit of a shot in the dark. There has been mention of POKE!!53 to change interrupts in the IPC, Is this a Hermes thing? Are the three of you seeing this problem all using Hermes? Also in my last post perhaps I should have said... Does the same thing happen if you try to LBYTES outside of the ...

Re: Possible problem with cloned SGC and Minerva 1.98

A few odd thoughts. I don't have the Minerva source code to hand. But I think that normal loading and scatter loading use the same routine to actually read the sectors off the cartridge, So it does not sound like a timing fault in reading the sectors. I don't know if its anything to do with slave bl...

Re: Possible problem with cloned SGC and Minerva 1.98

I have been comparing my MDI driver and Minerva source codes. But I cannot see any difference where I thought the problem was.

So I had a search in the forum https://qlforum.co.uk/viewtopic.php?f=19&t=683&p=4979&hilit=minerva#p4979 from when I was hunting it.

Re: Possible problem with cloned SGC and Minerva 1.98

Hmm, looking over the list I suspect the scatter load of the MDV device driver is broken on later Minervas. Further experiments now show that it always crashes when you LBYTES a file that is exactly 4096 bytes or bigger. Too late to investigate further, but the bug will be in dd_msvsc_asm I guess. ...
