I have built a c++ library for reading binary spec files from inst packages on my github. I have some irix 4 packages to throw at it, but a few of them elude my reversing efforts of what format exactly is used.
Together with the mydb program here , it should indeed be possible to cobble up some irix 3/4 gendist together.

Link to that github?  Here are some patches to mydb.c for extended functionality:

I'd like to see if we can use gitea on IRIXCE.org for this. Github doesn't even work over http. I'm going to be applying some upgrades and configuration fixes to it tonight and tomorrow.

I think that it's rather unfit. to use a service that doesn't even try to cater to older machines.

You can also use source hut or something.

(I'm applying updates to gitea!)

[dexter1]

Link to that github?

It's over here

Thanks for the mydb update. The tool is a bit crude (so is my specfile program ;-) ) but it does give us some lead on how irix4 packages are built up.

[Raion]

Looks good guys.

I'd like to eventually make something, I guess we could call it "libtardist" which could be used as a basis to make package creation programs.

[hbent]

In the meantime, please enjoy putty and doom, which should really be all you need to get started in life.  Both are mips2.

[Raion]

I'll make a repo for these if hbent wants these packages.

I have 4.0.5 on the Indigo R3k (and, if you want to be even older, 3.3.2 on the 4D/25), but frankly I'm too lazy/ time pressed to do much on either. Use them mostly as "progression of IRISes" type stuff, but don't even have much of anything beyond the demos that runs on the 3.3.2 box.
6.2/6.5 is much easier.
