Re: QL / PASCAL

Just as an info, maybe someone is still interested I definitivly am :) That was - at least in my opinion, and I think I deserve one :) - not exactly a bug in vlink , but rather was a missing work-around. It's an age-old bug in QDOS that it will allocate the stack of an executable whose load-size is...

Re: QSTAR 2

Dilwyn,

That's one of the (the main) reasons why I'm not sure whether the header preservation methods we have devised over the years are really of any help at all or just create even more confusion. I sometimes think it 's the latter.

Re: Plug-in ROM without $4AFB0001 Header

The EPROM was apparently used as a means of copy protection. Had I done that, I'd likely have coded the EPROM contents as position-dependent, which makes it next to impossible to simply load the EPROM contents to some other address and run it from there. EPROM_LOAD is indeed SMSQ/E only (to work pro...

Re: Plug-in ROM without $4AFB0001 Header

I was wondering if anyone could confirm, please, that if a ROM at $C000 does NOT have the $4AFB0001 header then the QL does nothing with it? i.e. no initialisation code gets run etc. And therefore any program that wants to make use of whatever it has in it, HAS to call routines in it directly pleas...

Re: QSTAR 1

Really nice game, Andrei, and nicely polished presentation! I did know it as a demo program ("D-Star") for the ZX Spectrum that is part if the SDCC C Compiler, but yours has much nicer animation, fonts and color. Couldn't find much of a flaw in it except maybe that the animation delay you ...

Re: Psion Abacus

You're doing it right. To my knowledge, there's no simpler way to execute MOD in Abacus

Re: Get yourself a bargain (not) - £800 for an untested QL

Anyone who buys off of AliExpress ever go 5 or 6 pages deep and find $5 items for like over $1,000? What is going on there? I had to replace a mini AV-to-VGA converter that you can get for about $4, and I was trying to fit things into a "$10 and get free shipping" window and kept looking ...

Re: Get yourself a bargain (not) - £800 for an untested QL

Could be my attempt at selling my QL stuff when the best wife of all asks me to get rid of some of my old computer crap. "well, I tried!" :)

Re: Floppy problemsve.

Actually, a floppy drive connected to the controller, even if connected the wrong way round, shouldn't prevent the QL from starting. Maybe the PSU has aged and has problems providing the Amps properly?

Re: PiStorm

Stupid question, but how is an emulated processor on a real QL going to be better than an emulated processor in sQLux or similar? Since the emulated Io is superior to genuine IO in every way, couldn't we just make a QL-fitting carrier board for a CM4 for the QL case? That question is very valid, bu...
