I think doing sage developement and testing on a machine with just 512 MB is not a good idea. Sage is a ressource hog and it will not work. I think it is better to use a good 64 bit machine with lots of RAM and either dual boot it to a 32 bit distro or use virtualisation as mentioned. Quemu is fine, although virtualbox/VMware could be substantially faster, i.e. better suited for testing purpose.
For the sake of completeness: This is the link to some debian based installation images wich are fine tuned for very low spec machines, also going back as far as debian squeeze for really old hardware. I do not recommend you try them for sage developement, because it will not work with new sage code. But if anyone wants to revitalize some old machine this might be the best option. It is completely built with debian live, but has setup and code from puppy linux, which is very light. https://debiandog.github.io/doglinux/zz06other.html best regards john.c...@gmail.com schrieb am Dienstag, 17.
