Tonight I've found this page, lots of old devices, appears that the download links that are hosted on the hosting site (exquisa.de) are still active and available.
http://www.exquisa.de/Rabarber/SEITEN/N ... _devic.htm
(EDIT March 2016: This link is gone - site is now at http://www.exquisa2.de/Rabarber/SEITEN/ ... _devic.htm).
There are no less than 17 pages of devices here; each page accessible by the drop-down at the top of the page.
Specifically, the first few pages ('seite'), the devices hosted on:
- pulsardevices.de
- planetz2.de
seem to be dead... web.archive.org doesn't appear to have file content for these old sites either...
My lord the world was a gaudy tasteless place back in the early noughties! Some harsh looking gui's back then!

I've reaped the available files across the 17 pages, trimmed out the ones labelled 'demo', zipped them, and put them up on my dropbox here:
https://www.dropbox.com/s/q9en6c6xv4pu8 ... isa.de.zip
I've not categorised nor tested any of them - so use at your own risk.
At least with the web pages above, you will be able to find the brief description, and a picture of the gui...
No doubt at least most of these come from a time with the old Preset system etc.
Here's a full list. Every file is a .zip, unless otherwise indicated...

No doubt, there'll be crossover here between what Mr. Arkadin has listed on pages 1 and 2, and all of guppy's large and most extensive classified and non-classified devices on page 4 (archive files still available), here:

If I am breaking any rules or any developer agreements, please let me know, and I will remove those offending items from this list, and from the zip.
Since deviceplug-ins.com is gone for a while, wonder if we could get his freebies (at least) collected together?
Here's the last good snapshot from webarchive - it won't have pulled the zips tho...
