Both Mozilla SpiderMonkey (in C, C++) and Google V8 (in C++) should 
(cross-)compile for Linux on IA-32, i.e. Intel 80386 and compatible 
architectures.  (Windows XP and later does not run there.)  However, I do 
not think that alone gives you disk I/O, too (AFAIK, XPConnect is part of 
the Gecko DOM API instead).

I agree that an ECMAScript implementation for Intel 80286 and earlier will 
have to be hand-crafted, perhaps based on that code, as there are 16-bit 
versions of Netscape Navigator 2.0 (which introduced JavaScript 1.0) in the 
evolt.org archive, but the SpiderMonkey source code was essentially 
rewritten when it went open source, and you would need Java and LiveConnect 
for disk I/O unless you write it yourself.
