Welcome to the WUDSN ursel home page

WUDSN ursel - or short WUDSN - is a demo group founded in 1991. There is an explanation why the group and the site are named like that, but that's a different story you can find in the FAQ. For the time being it should be sufficient for you to know that I, Peter Dell aka JAC! am one of the members ever since. I have created this web site to offer my tools and productions and to share the fun I have had for more than 20 years now with my Atari-8 bit computer and other classic computers. To learn more about me and what I'm doing, check out this personal interview that I gave for ANTIC - the Atari 8-bit podcast.

The!Cart available again in the A.B.B.U.C. Shop

Thanks to the support from the A.B.B.U.C., a new batch of The!Cart is now available in the A.B.B.U.C. Member Shop for the price of 75 EUR. You need to be registered in the A.B.B.U.C. forum and your member ID must be linked to your account. If that link is missing, just PM one of the A.B.B.U.C. forum moderators.

A very important warning: Don't use RespeQt versions from late 2018 up to 5.3 when flashing your The!Cart. Use AspeQt instead. Or use RespeQt version 4 or a previous version from https://github.com/ebiguy/RespeQt/releases as they are working properly. A fix for the current RespeQt version is in the making.

Atari Action! and Atari Action! Editor update released

I had received some requests for improvements to the standalone Action! editor. So I have decided to finally make it an integral part of the Action! project. Here's what has changed:

  • The Action! program is now called "ACTION.COM" in all disk versions.
  • The Action! editor is now included as "ACTIONED.COM" in all disk versions.
  • The Action! editor now has a build date, just like Action! itself.
  • The Action! editor documentation is now included as "ACTION.TXT" in all disk versions.
  • Disk version for DOS XL added.
  • Passing command line parameters to the Action! editor now also works in DOS XL.
  • Incorrect status text output has been fixed in the Action! editor.
    There had been some places in the source where ASCII/ and ATASCII was mixed up.
  • The README.TXT file on the disks now has correct EOL characters.

Feedback, especially regarding the documentation and editor are welcome!

Prince Couple Patricia 001. and Peter 011.

Since November my wife and I are acting as princess and prince of carnival in our town. We're partying hard and shout "Da je!" all the time. That's is why you don't hear much from me recently on the Atari forums. I'll back after we return from the Betty Ford Center in some weeks ;-). So who's first to spot the 3 Atari related things on our official picture?

Silly Venture 2k19 Video Invitation

Once again Grey made it! Cool to see the original designer RJ Mical promote the party. Massive thumbs up. I've never owned a Lynx, but the hardware combination is really nice. I always thought it was using a 65816 - until Heaven told me it also has a 6502 ... and beat me with releasing a demo for it first! Visit http://www.sillyventure.eu to read more about the party - and see you all in Gdansk!
