Re: QPC Print

I run it as a virtual printer (as described in the manual) via a Fritz!Box WLAN router, works perfectly.

Re: Return of Y2K Bug?

I wonder if anyone has come across any QL software which falls foul of this through using 2 digit dates? I remember the Sinclair version of "Cash Trader", which had this problem (later corrected by more recent versions, non-Sinclair). I wasn't able to install the freeware version on QPC2 ...

Re: Spotted on eBay

Not my auction, but today I spotted a QL complete with GST 68K OS. https://www.ebay.co.uk/itm/Sinclair-QL-complete-with-GST-68K-OS/283757528122 Does anyone know how many of the GST boards were made? Do you have to have the GST ROM board, or is there a way to softload the OS on a QL? Very interestin...

Re: QLiberator decompiler

I have been doing some work on renaming variables and proc/fn names in the new decompiled QLIB_BAS source. The idea is to make it all readable and understandable. I'm not altering the code in any way, just doing the renaming. So far I have renamed about 80 out of 400. This is all a guessing game, t...

Same with the first hardware Atari emulator from Futura Datasenter, they just supplied a QDOS disk for patching your saved ROM code.

Re: Reverse Engineering

I think, you should ask the copyright owner (mostly the author). If the source code is lost (DM5 or QLiberator), perhaps they are very pleased, if you are able to help them out.

Re: QLiberator decompiler

Oh, 3 seconds compared to Martin 's 2 hours with Qemulator? Can't understand this. What's about those Turbo lines? You should use a clean OS, without any extensions.

Re: QLiberator decompiler

Just try it, you're welcome ;) But that alone doesn't work (in that procfun). The main problem is, that they do not set global variables for the use of the screen sizes even though bigger ones existed in the Atari drivers during the development of QLiberator.

Re: QLiberator decompiler

BTW: The window MOVE takes place in "procfun34401", if someone wants to investigate, "var0388" is true, if PE is available. Inside procfun34401: IF PE then WM_Sptr and WM_Rptr are both called, else an inkey$ loop is entered where the cursor can be moved around. When ENTER is pre...

Re: QLiberator decompiler

Perhaps, we will sometimes understand, how QLiberater and its runtimes manages this (if someone disassembles the runtimes and can really understand, how it all works). For me, it would be interesting to know, if there are similarities to SBASIC as the compile times are the same, if QLiberator compil...
