So far there are two events in Gothenburg that I'm aware of. The first one is Datastorm , Feb 5-7. It is an international C64/Amiga demo party which has been sold out for months but who may take individual visitors at the door. The second one is Retrospelmässan (April 24). It will be a video game tr...

CSM is a higher level format, preserving only the data instead of pulses. I think cbmconvert will extract PRG out of those, which will lack info from the tape buffer but otherwise contain pretty much the same info. I'm not sure how CAS/CSM translates to the T64 format, but I agree those files are qu...

Is it at all possible that the sd2iec/uIEC could emulate two drives in one device, i.e. 0: and 1: ? If so, it could've been setup with game disk into 0 and save disk into 1. It would be quite natural on a PET but unusual on a VIC.

Hm, doesn't anyone of the VIC-20 demo coders or VICE developers for that matter have a NTSC VIC-20? :shock: Several of us mortals have, but even with the hardware at hand it could be hard to determine what to look for and make test programs. Previously I offered tlr to borrow my NTSC VIC if he thoug...

Dragos makes a mention of the extensible firmware interface (EFI) which is a layer between hardware and operating system. It replaces the good old BIOS, and EFI implementations can be much larger and more complex. EFI removes the old 1980's PC limitations modern BIOSes tend to build upon. I suppose ...

Speaking of ports, a while ago I begun working on a line-by-line conversion to machine code of Ten Ten, but I didn't get very far. Perhaps someone else wants a try, someone who is even more motivated and skilled in machine code than what I am. Not that the program needs to get any faster and the maj...

Perhaps HP, Dell and all the others consider that CPU you mention too expensive for their customers, while Apple users have no problem paying premium money? After all that is what they've been used to do for 20 years or so. But you'll agree if that dual Nehalem PC shows up, hardware wise the CPU ins...

Ok, perhaps bad choice of word. Forget "flag", call it selector instead. Of course I might write ON F+1 GOSUB .. but it is almost even more cryptic.

Well, my case of thinking was that more advanced subroutines would be called upon successful or incorrect input. Perhaps whole moves will be performed, routines that may even get called from other parts of the main program. In that case, it would make more sense to break those routines into subs and...

I'm most excited about some sort of support for other assemblers. For a while now I've been meaning to try SSS, but I'm unwilling to drop DASM in favor of the CC65 assembler.

Good question. The ON X GOTO/GOSUB will only branch on X>0, so F=0 would bypass both the error message and the greeting. Thus F=1 from the beginning would assume the user made a mistake, and setting it to 2 (in this case F=F+1) simply upgrades the branch from error to greeting.

The biggest issue I have with Apple and its Macintosh are the "benchmarks" they liked to run in the 1990's, in a time where the PC world was in a crazy Megahertz hunt. Obviously PowerPC is clocked at lower frequencies than your average Pentium, but it got absurd at the point when Apple ins...

Personally I prefer INPUT with strings A$ and then apply some VAL() or possibly ASC() function to get a numerical value from it. In that way you won't get ?REDO FROM START if the users inputs a non-numerical value. 10 input "1 or 2";a$ 15 a=val(a$):f=1 20 on a gosub 200,210 25 on f gosub 1...
