Re: Vertical screen interrupt

Agreed. The web page I pointed you to describes exactly that minimum of the system you need to keep "alive" to achieve what you want - Remember the Vectors to the ISRs are in ROM that you cannot modify, so you need to live at least with some OS code handled to get your hooks called. Tobias

Re: Vertical screen interrupt

radastan, there isn't exactly what you're looking for. (Like an interrupt vector you could bend to point to exclusively call your own routine) The 50Hz interrupt is basically the engine driving the QDOS multi-tasking and hardware interrupt handling, so anything fiddling with it is close to heart sur...

Re: Extended expansion connector...

For new peripherals, if drivers can be developed maybe only USB should be supported for new peripherals devices? I'd estimate the likelyhood that USB drivers will ever be written for the QL below 1%. USB would almost certainly mean another little computer running the USB drivers, and connecting to ...

Re: New Online Chat

Derek,
probably not a good idea - I wouldn't want to have my random personal blah-blah recorded and replayed a hundred times by people I wasn't talking to at that moment. If something really important is discussed, I guess someone will bring it forward into the forum itself.

Just my 2 ct.

Re: Foreign keyboard

Dilwyn,

Definitely german, as it has a qwertz layout, carries the ÄÖÜ umlauts and the "ß" (which would be missing on a swiss one, although I'm not sure there ever was one...).

Re: C cross compiler

And, to increase the choice to two:

There is a Linux gcc cross compiler for QDOS on the same site:

Re: SDHC adaptors...

Rich, Perhaps the answer here is to avoid the reference to native mode completely in the main user manual, as it could be confusing. A separate appendix or even manual would be ideal to concentrate on native access and maybe the technical aspects of how the driver layers work together, so that other...

Re: SDHC adaptors...

Rich, thanks for the comments and best wishes to Simon. I am sure Peter will have one or the other things to say on design decisions (There's always a "different way to do things", IMHO. Sometimes it's better to just use what you have at hand and have something that works instead of trying...

Re: QL-SD Card Interface

Documentation says don't use with Gold / Super Gold card as it isn't compatible. What about a Trump card? "Not compatible" regarding non-working GCs and SGCs is probably not quite the right term - There is actually no obvious principal reason why it shouldn't - But that doesn't help the f...
