Hello, A question about file transfer - is it safe to mount a QXL.win file on a Q68 SD card directly in QPC, or will this cause fragmentation? If this is possible it would obviously be the ideal method of file transfer between PCs and QLs. D. Yes, it is possible and will not cause fragmentation (ne...

We have tested Sernet at 115.2k - worked perfectly fine.

Anything beyond that is currently missing OS support (and thus, a real application).

Giorgio, yes, a job can change its name, if it is prepared to do so. Some programs change the job name to the file that is being worked on - QD, for example will display the file being edited as part of the job name. It is, however, close to impossible to change a jobs name "from the outside&qu...

2G007 ULA aging, something I have not thought of yet. If ever needed to be reengineered, we only have documented amplifier reading cascade, a block diagram with amplifiers for writing is not documented to my knowledge. I would expect the stock of available MD ULAs to last way longer than the availa...

Also, newly created jobs inherit the table from the creating job, not the owner job. Of course, if that job goes away without clearing JB_TRAPV you're in big trouble when an exception occurs... That sounds a bit like a system design fault to me, even if it's documented in the Technical guide (p. 14...

Something along the lines of (Untested, no QL at hand...) (i.e. POKE_F and PEEK combined) should work. POKE_F is part of Turbo Toolkit.

NB - I consciously changed the variable types from INTeger to F.P. in the formal parameter-list to highlight another 'curiosity' (and bone of contention for typed-data purists...) of S*Basic - namely that the types of x and y are inherited from the types of the actual parameters passed at run-time....

I'm also trying to figure out how to make use of more than 8 colours on QPC2. I know there are SBASIC commands COLOUR_PAL and COLOUR_24 to change the palette but I'm looking for documentation to do this from machine code. Any ideas? . Just realized this apparently was never answered. I am pretty su...

Most exceptions stack the following data on the SUPERVISOR SP, or A7 in the exception handler: 4(A7) = PC value that caused the exception. 0(A7) = Status Register value at exception time. That's three words in total on the SSP. Last sentence is correct, but doesn't fit your layout: address for PC s...

Up to issue 5, this jumper pins were there - After the QL ROM story had settled, they removed it in issue 6.
