You most welcome :)

This may require more/different tests. From real life experience, VIA C7 
CPU with 512MB RAM on Mini HP couldn't breathe Lubuntu but had no issue 
with Xubuntu 12.04 LTS

The oldest CPU that I have is P2 and that is definitely not for daily 
use but rather to be kept at a Museum or something like that :)

These my other CPUs that I have:


Both handle Lubuntu with no problem except with movies with 720p 
resolution or so.

Last time I had Celeron was 10 years ago or more so not sure about the 
Lubuntu 14.04 how well can work on that CPU.

In short, I think P3 is hopeless unless someone can prove the otherwise. 
It might be a waste of time to prove it.

We all know that it is a challenge. We're in 2014 and we are talking 
about older than 10 years old CPU. 10 years ago (2004) none of today's 
technologies were available. And, at the same time, it also seems that 
none of the old technologies are available anymore. We're talking here 
about the 'normal daily computer usage'.

As for special cases, that is something else.
Example: theoretical experience to prove the very minimum and how far 
one could go. These tests are useless for the users but it is just for 
curiosity or fun.

If FOSS/Linux Communities have some data/figures of how many 'very old 
machines' are still alive as of today, our mission could have been much 
easier and shorter. As long as we are doing all that blindly by assuming 
'there are' very old machines somewhere over there is not 100% helpful.

Here is another suggestion from me ;)

How about a Wiki Page called: *Special Cases *to be created under:

On that page, users with very and I mean VERY old machine can list their 
hardware details (a must) on a column and on the other column states 
whether Lubuntu was installable on their machines or not? then another 
column to state whether Lubuntu is usable on their machines or not?

By achieving that, you provide 'real' experience for 'real' people with 
a proof that on a specific old machine, Lubuntu was installable and usable.

This will work as a check-list for very old machines that is below 512MB 
RAM and P4 :)

I'd be glad to create that one if you guys like the idea :)

Also, on that page, you can list the requirement that is for less than 
512MB RAM - the same that your original email has: 

So, this page:
Should list few lines - as I suggested earlier: 

While the new one:

Will list the other lower/minimum requirements and that table which the 
users will fill every time there is one successful story to share :)
