Hi, I need univos.zip right now, but Brandonw seems to have removed it, and I can't find it anywhere else.
If someone has a copy of it on their hard drive or knows a mirror for it, please help me.

Thanks in advance.

Brandon says he's just reorganizing his files, so UnivOS may be back soon. If you tell us what you need it for, perhaps we could help you find an alternative.

Hi,

I have a TI-84+ and I'm finding that my friends are abusing the (left)(right)(on) effect as well as the (2)(8)(on) and (5)(8)(on), and as a result my calculator gets cleared almost daily. So I set out to downgrade my firmware to something less than 2.40; I've got a copy of the 2.21 operating system but it refuses to validate. That's why I'm looking for univos, maybe it will let me install 2.21 on my calculator.

If there's a better alternative I'd like to know.

I don't know why you wouldn't be able to downgrade the OS normally. However, if you can upgrade to the latest version of TI-OS (2.43) you can use this patch to make PTT do nothing: http://www.ticalc.org/archives/files/fileinfo/418/41803.html

My patch (the one suggested by Dan) is not enough, it doesn't patch [ON]+8/2. The other patch is on Brandon Wilson's server. You'll have to wait until he's done reorganizing, though.

I think it's called PTTP. The file's probably called PTTP.zip, if you want to search for it on the interwebz...
