Hi,
do you keep your old OS versions somewhere, or do you trash it? I keep "TextLiner OS", PortixOS 0.4, "DexPortixOS" and Patlock 0.0.1 binaries on separate floppy disks, the original sources at my external HDD. Just for old time sake, after 10 years to tell: "this was my first OS... 2005"

I keep old disk images around for exactly the purposes that you mentioned but I find no need to keep around old source trees. That is what CVS or Subversion are for: If I need to see how I coded something in a previous version, then I'll just use one of those tools.

EDIT: Speaking of nostalgia - 100'th post.

In the US, it's a good idea to keep them around -- just in case you ever need to prove copyright issues. Blank CDs are cheap.

I have copies all the way back to the wee baby DiNS v1.01a

The only code I'm really missing is that from Mattise 2.0, which was never released anyway and is mostly in the CVS and SVN on Sourceforge. Everything else I still have - and still use at times. The old Mattise 1.0 network stack is still useful now (mainly the ne2k driver and the ARP code at the moment) .

I've got a lot of copies of the source tree I don't even know now which version is newer which is older It's easy to compare two copies for version, but it's not to hierarchize a few dozens from oldest to newest. Do you know of some directory compare app which does this efficiently?

I keep the old sources somewhere in a maze of folders and files. hope I never have to look for them, I might get lost!

Nowadays, with so large HD space, why get rid of anything?

I embed my old files in to OneNote along with pages of hand written scribble describing it all.

i keep evry thing in my hard disk and also in my gmail...

I should have someting on a 5¼" floppy somewhere

I've kept every version of my OS, mostly for humbling purposes. I wince every time I look at that folder.

Have all my old DexOS vers backed up on CD-R, from the day i started.

I have just about every bit of code I've ever written, including old versions of my OS and my OSDev attempts prior to that (all of which were awful :p)
