Greetings,

I have a very old laptop (486 - 4mb ram) that I want to write simple
java programs on. Is there any version of Java for Dos still out there?

Thanks

You might be able to run Linux on that machine, it's tricky, and you
need to use non-graphical installers, but you could easily run java from
that. Just make sure that you use as little boot loading stuff, and use
a small kernel. There used to be a small memory HOWTO.

You could install an older JDK from
<http://java.sun.com/products/archive/>.

I'm assuming that your laptop has Win95/98 (I can't imagine a DOS-only
laptop). The Windows installer requires a graphical OS.

For the Windows version of J2SDK 1.2.2 it's recommended to have at least
32Mb. See
<http://java.sun.com/products/archive/j2se/1.2.2_017/README.html#system>.
For JDK 1.1.8 this maybe less, but I couldn't find any info on this.

If you want to compile/run commandline progs only, 4Mb might be
sufficient (but only just).
