Hi Martyn, - I've noticed that the scout appears to have some data encoded into it (some variation of the NET ID?), even though it appears to be completely ignored, however can this data be used to reliably differentiate between the standard protocol and TK2 protocol? Jason Jason, what's in the sco...

Tomas, The S-Basic reference Manual has a pretty extensive and detailed explanation of the OUTLN command - I don't think I can do any better. What needs to be mentioned is the difference between a primary (#0 in most cases) and a secondary window, because OUTLN sets different limits on them OUTLN #0...

How might detecting this tie in with detecting and enabling caches on the 68000, 68020, 68030 and 68060? Enabling cache on a 68000 is REALLY hard. Detecting it is even harder ;) In earnest: You don't detect cache on a 68k CPU (some cache modes make it impossible to be "seen" by the CPU it...

I was hoping to divert some of the QDOS drawing routines to screen1 from within machine code. As I read somewhere, long word channel ID encodes screen{0,1}, possible? None of the original QDOS drawing routines could actually draw to screen 1. And I doubt they can be made to do so from the outside. ...

Typical non-Minerva applications that make use of the second screen need do the following: Allocate any needed memory from the system Go into supervisor mode and never leave it again while the second screen is in use. Note that implies that your program will take over the machine entirely. ... and ...

Pre-1990 systems/OS had the huge disadvantage that there was no common printer model/driver architecture built into them. So, every application had to come with their own printer drivers (for any model in the market, which was a huuuuge task). Today, most printers aren't even intelligent enough to p...

But don't confuse the SD cards - neither will work with the other's media.

Another reason why it would do well on a separate CPU.

The keyboard is handled by a separate CPU on the QL
