Apache has a reputation for being flexible and adaptable, and here's the proof: someone has compiled the Apache source code and is running a Web server on his Playstation 2 (albeit running Linux, not the native PS2 operating system):
"I've been a regular user of Apache now for about a year, 1.3 and more recently 2.0. Recently Sony released a kit to turn their PlayStation 2 console into a fully featured Linux machine (hard drive, Ethernet etc etc). This kit has been gaining great popularity amongst the Linux community, and several users (such as myself) have already decided to use it as a webserver :)
"Anyway: to get to the point: the PS2 only has a 300mhz MIPS processor, and the compile time for Apache is quite hefty. Another discouraging factor for any would-be Apache on PS2 users is that compiling "anything" can be quite a daunting task for many people. For this reason, I've decided to provide compiled Apache 2 binaries for download.
"These are currently available from http://www.phi-web.co.uk/ps2-apache/ and I will endeavour to provide the binaries for each new release of Apache 2 within a day or so of it "emerging". I just thought I'd let you guys know about this potential (admittedly small) market for Apache. With any luck, by making binaries for it more high-profile, more people will purchase the PS2 kit, and hence get interested in Linux."
