Hey y'all-- didn't expect such a big response! Sorry I haven't been around as much, but it does give me a lot to come back to! Yes.. WSI was the weather data and software solutions side of The Weather Channel until the IBM sale in 2015 or so.. WxPro hasn't been in use for a long while (or supported, of course, since it's an IRIX app), last evidence I could find of it in use was 2013. To answer the person asking for what I know, WxPro itself was the software used to generate weather maps and other graphics found on The Weather Channel and various other news stations. TWC used it up until 2008, and like I mentioned, I've found videos of it in use as late as '13.. makes me think it's possibly still out there somewhere. And it seems it *might* be, based off some of the replies... I appreciate y'all stepping in and being detectives! I will definitely see what I can do about the machine on the reddit post.
Yes, that's my YT channel, and yes, techknight (who's in the same group as I am) does also have an XL. Our group has done a lot of work with the XL over the years, including data recovery. The only issue is that--unfortunately--the XL never came with WxPro on board! Its rendering process was, however, very similar to WxPro as it also did not render graphics in real time.
