[quote="Derek_Stewart" The best way to remove ghost image of the other side of the scanned page, is to adjust the scanner Gammer and Brightness / Contrast settings. [/quote] Edit: Christian had already written that. Nope! Simply put a fully black paper (or even better card) on the back sid...

Wow! I know a bit of QL-Hardware!

But here ... I'm out of order...

It seems to work in high colour mode on my HD monitor too. Just remember to QPC_QLSCREMU 4 first. Also from me: Thank You Jochen Hassler for the nice EXE of Psion Chess! Thank you "pjw" for the tip with "QPC_QLSCREMU 4", works great, see screenshots. PsionChessOnQPC2_3D_FullyMul...

Theres a version that comes with QLE that works fine in QPC2. Its not PE, but it doesnt misbehave nor does it take over the system. Both 2D and 3D seem to work ok. And it still beats me most of the time ;) Thank you! I have found it on QL/E and it runs perfectly, unfortunately here only with QL res...

Have now downloaded Psion Chess for DOS (it's easy to find with Google). HORROR! Does not run in Windows 10 on XP it only runs fullscreen and without colours AND with an horrible upscaled resolution ("pixelig"). As far as I can remember on the QL it looked really great in 3D mode - on DOS ...

Warning: QLC (Lattice C 3.02) has one really horrible bug in stdio.h. When it returns EOF (which must be an int - that was always so, even in K&R C), it returns a char. As char is signed on the 68000, when the character code FF (decimal 255) exists in a file, it is sign extended and EOF (-1) is ...

Thank You Marcel!

Very nice program, lists even the name of the REDIR device from Phil Borman.

Thank you, would be a way, but I find it too cumbersome. Perhaps I try to write a Machine code program, which scans the open routine of all device drivers for vector 122 (IO.NAME) and afterwards looks for the next jsr call and look 6 bytes afterwards for the name. Will most probably be more complica...

Is it possible to get a list (e.g. in a string array) of NORMAL device drivers? For directory device drivers this is quite easy: 10140 REMark create string array with list of directory device drivers: 10150 __sys__dirdevs%=0:DIM __sys__dirdev$(19,10) 10160 dd=PEEK_L(VER$(-2)+72):REMark get pointer t...

Thanks a lot, all suggestions seems to be interesting !
