Re: Sam the Little Spaceman

That's Norman's docs that say "preserved after TRAP#4" - Other's don't. I guess that's more of an observation than a system commitment. From a JS disassembly I can determine that A1 isn't preserved at all. The only thing a TRAP#4 does is to set a bit in the job header, which is read by th...

Re: Sam the Little Spaceman

Its a documentation bug if anything. The official documentation, ie QL Technical Guide, now QDOS/SMSQ Reference Guide, has always stated that A1 gets smashed during the IO.OPEN call. The QDOS/SMSQ Reference Guide is now in version 4.5, available from Dilwyn's cornucopia. While its not perfect it wi...

Re: Another noob question: ROMs

AH never had the "dongle" - These were "PM" and "FB" (jokingly purported to mean "PreMature" and "Full of Bugs", but actually, the initials of developers were used, I think). If you download a PM ROM, for example, from Dilwyn's site, you'll see it o...

Re: Returning values from a basic extension function

I finally managed to debug my basic extension... it turns out that there are some name table entries with a name pointer of FFFF, and things went screwy when I tried to follow them into the name list. They are SBasic variables of some kind (maybe unused or invalid or something?) , so obviously when...

Re: Dr. Jim's QL Dumping Ground

QLAY and QL2K need the NFA.ROM for emulating file access, SER and PAR ports and the like. This ROM is usually located at $C000. Qemulator doesn't need this as the functionality is already built-in. You can specify Toolkit II as a second ROM in QLAY/QL2K at address $C0000 (note 4 zeros rather than 3)...

Re: QL on the Raspberry Pi...?

I have a Raspberry Pi model 3B which runs the ARM v7 version of uqlx successfully at a speed about 100 times the original QL.
Have no idea though whether it works on the original Pi. I suspect it will be somewhat slower but still faster than a BBQL.

Re: The background to my presence here

Yes, my mistake. But even windows directories with a qlay.dir file do not work in QL2K. I tested it with the sample directory from Qlay2 dir win1_ returns "not found" when win1_ si mapped to the sample directory WIN, which has the qlay.dir file Have you imported the file names using qlayt...

Re: The background to my presence here

Aaaaaaaaaaall right, enough talk of football and running before I can walk... Am I being dense here, or is there no way to change (admittedly unregistered) QemuLator's aspect ratio? If I set the Zoom under "View" to either 100% or 200%, the pixels aren't of a consistent size. As I underst...

Re: Trying to initiate TKII

Hello, I'm working with an original BBQL to which a Cumana floppy interface (1.16) and Miracle Expanderam (512K) are attached. I'm trying to launch TKII from floppy using the following command right after power-up and F1: 100 base=RESPR(16384):LBYTES FLP1_Tk2_Ext,base:CALL base The TK2 file definit...
