Moving LK1 from South to North does affect the display. According to the technical manual, that is the 32/64k switch. Yeah it swaps the top/bottom 32K so in theory may have demonstrated different fails (though you'd tested RAM). By SAM, do you mean the 783? Yep, so pin 14 of the SAM to pin 34 of th...

ROMs check out. But I don't recognise that failure... Couple of random thoughts to check: make sure there's a jumper across one half of LK1 (bottom-right), maybe try moving it to the "other" side. I think if it were not present at all you'd see something different though. Check E/Q from SAM are gett...

Yes. For the most part, you can sort of get away with CLEAR200,20000 but I think there's something to do with the operation of VAL() that can overwrite that extra byte. So stick with CLEAR200,19999. The stack then begins below the allocated string space - seemingly minus another couple of bytes (whi...

Next release will let you just "-no-cart" for the same effect.

Would be useful to have an option - cart none and have it behave as if there is nothing plugged in.

-no-machine-cart should do the job - each machine has a default configured, that option will deconfigure it.

I've pushed out a snapshot build here that might do the right thing: https://www.6809.org.uk/tmp/xroar/

BTW is there any reason why windows *NEEDS* to have -C in addition to the flags? I'm presuming that -C is telling xroar to do something it only needs to do on windows? So why not do it automatically for flags that need it? Or at the very least tell the user that they might want it? As getting no fe...

Running with -v 2 will show the actual path for each rom loaded, so in windows you'd run xroar.exe -C -v 2

(That's the case for the current version, 1.7 is long enough ago I can't remember if anything to do with that would have changed).

Not without a little extra trickery. On the CoCo, Extended BASIC inserts a RAM hook for CHROUT that performs this "return to text mode", and you can work around it with POKE359,57 - POKEing 126 to return to normal behaviour. But because the Dragon has a combined Extended BASIC ROM, they felt no need...

Excellent news. I should be able to come, and though I'm not sure anything I have is terribly exciting, a table to put it on would be useful
