Talk:Ancient UNIX

V5 vs SysV
To the well-meaning person who redirected the V5 link to UNIX System V: Unix versioning is rather complicated, and differs radically based on what part of the family tree you're talking about. Fifth Edition is actually a Research Unix and predates the earliest versions of SysV by over a decade; as far as I know it was never released commercially, and operated at only about 50 sites. (Frankly, the only freely available SysV version, OpenSolaris, would probably plow a GBA into the ground and bury it. V5 is far more lightweight.) Haikupoet (talk) 04:12, 5 December 2007 (UTC)

Compatibility layer vs. Emulator
I made an edit to change a piped link to not go to compatibility layer, but instead go to emulator. I think it's just important that people know the difference between these two things. An emulator recreates the hardware to be emulated in software, and some examples are SIMH and QEMU and AppleWin and MAME and VisualBoyAdvance. However, a compatibility layer is a different thing entirely. It does not emulate hardware, it just changes system calls from one format to another. E.g. one example, Wine translates calls to the Windows API into native Linux calls, and the FreeBSD OS has a compatibility layer for older GNU/Linux applications which translates Linux calls into calls for the FreeBSD kernel (often simply called kFreeBSD). This Talk: Page edit may be directly in violation of Talk page guidelines, and if it is, I'm sorry, but I'm trying better to be bold, and I think that knowing this (and that Wikipedia has articles on both things) is important not only to the well-being of this article, but, like, a zillion other ones. --Cogburnd02 (talk) 20:31, 14 July 2010 (UTC)
