I used to provide the complete Chipdir in zip format but the .tgz format is about 30% smaller and much more standard and almost all of the mirror sites use Unix anyway and almost no PC user knows what .zip is anymore and how to handle it, so... But if anybody asked I could provide a zip version. I also provided emailed versions in parts some years ago. By the way, instead of dwelling on the past, and as Martin rightly remarked: We should handle information as information and not as a screen-formatted product, and therefore I have been trying to think ahead and studied web services and pondered ways to provide the information in the chipdir as 'pure' information (like in the form of XML). Some of you may remember my experiment some time ago of offering a pin-matching script to find similar chips. Once I had to explain regular expressions however, that dampened my enthousiasm and I figured that there were more useful ways to spend on the chipdir. By the way Martin, didn't we email earlier about how sites should be adapted more to the blind? I remember emailing with someone at the westcoast of the USA about keeping the Chipdir blind-friendly and although I try to do that I suggested that he should ask the Lynx people to filter out all the Javascript stuff as they should (or interpret it as they could). I try to keep my site as fluff-free as possible, but it's not a blind-people only site and we can't ignore progress.
