Denial

You as a board admin might be able to push numbers up or down as you prefer. Personally I've grown tired about post count hunting but sometimes deletes my old posts whenever possible and people are pointing out who is posting the most.

From time to time, there still seems to be some interest from small industry or home scientists to get hold of a VIC-20 to interface with other equipment. I've been asked once to sell my VIC to one of those. In this context, the bigger C64 is not as attractive, as it has more complex timing and thus...

Bah. Would that be me, I had sorted all the carts after manufacturer and serial no before taking a picture, alternatively tried to put some pattern. They don't even seem to be sorted alphabetically.

Hm. My Othello game in the MiniGame compo 2002 was a quite advanced example of aritmetic math, converted directly from a Basic listing. Maybe I should put some more effort in commenting the assembly listing and put next to the Basic one. It could be interesting from a ML learning point, although I'm...

Oi, quick answer from Wayne. He had already acquired two Microair cartridges from his February ad, so he was not desperate to get a third one. This makes me wonder how uncommon it is, or maybe because he asked in an on-topic ham radio forum lead to more hits than if he had asked in any general VIC p...

Ah. In 6502 assembler, all additions (ADC) and subtractions (SBC) are done with respect to the carry flag. This is one bit in the processor register which remembers if the last operation was greater than 255 (the maximum value a byte can hold). There are a few more flags who work in similar ways to ...

Probably you plug the leads from a ham radio (amateur) into it and use it to tune in and search for other people on the radio network. According to this review of the C64 version, it is one of the best ham radio devices ever made, outperforming even today's hardware: http://www.eham.net/reviews/deta...

One of my friends in school had a dad who was into amateur radio and I think had interfaced it with the family's VIC-20 (which also was equipped with a Buti Plus cartridge I once borrowed). I don't know how he interfaced the radio though, probably through the user port rather than cartridge port lik...

I would like to become more disciplined, and try and at least do 15 minutes of working on programs, every day. Nah, then it almost turns into something you do for a living, although you don't make money out of it. Not even if I'm unemployed or retired, I think I would find the joy if I was working ...

I think the documentation (as always when it is open source software) is very weak. The included documents are sometimes outdated or applies to a different platform than the one you have, and the website is slightly unstructured with a haystack bug- and knowledge base. Maybe it is the price one has ...

Heh. It is a raw program file, neither a tape, disk or cartridge image. Thus, it will not easily autostart. I have now put a slow-loading TAP image on the web page: http://www.mds.mdh.se/~dal95acn/vicfiles/antiair.tap It could even be used with mtap or some tap2wav converter for those who like to st...

Technically, the VIC-I outputs the following frequencies: 36874 ($900A), freq=(Phi2/256)/(128-(PEEK(36874)+1 AND 127)) 36875 ($900B), freq=(Phi2/128)/(128-(PEEK(36875)+1 AND 127)) 36876 ($900C), freq=(Phi2/64)/(128-(PEEK(36876)+1 AND 127)) where Phi2 is 4433618/4 Hz for PAL or 14318181/14 Hz for NTS...

Theoretically, frequencies of musical notes follow a mathematical structure involving the 12th root etc. After assuming the frequencies put out by the VIC chip follows the mathematical formula, one could calculate the tone values and store somewhere instead of using DATA statements. However, reality...

I think there might be one or two bugs more - the only way to win is to appear right before (not hitting) the aircraft, and if you do, you still get a message about losing. Also, sometimes you will be able to escape a bomb as the two pass by eachother simultaneously. I'll see if I can come up with o...

Here is my entry - Anti-Aircraft Challenge, a direct port of the ZX Spectrum game with the same name which I submitted for the CSS Crap Game Compo 2003. If you prefer to download it instead of typing it in, you can get it here . Unfortunately I broke the rules by ending up with 25 lines. If we were ...
