The PS/2 Server 95 *definitely* didn't use the Pentium Overdrive. The
machines were available with 60MHz and 66MHz P5 chips. Later, there was
added a Type-IV CPU complex which came with a 90MHz P54C, a different
CPU socket (obviously) and different firmware.
The document you linked has none of the "server grade" PS/2s in it.
Peace... Sridhar
Having been at
IBM and working on the PS/2 series of systems, I can
tell you that the PS/2 systems were first with the Pentiums from IBM.
In particular the PS/2 Model 95 was the first. It was also the first
PS/2 to support> 16MB of RAM (I know 'cause I did the support in AIX
PS/2 for it...was fun having a 64MB system at the time...8 8MB DIMMs).
It was *well* before 1995 (as I moved to Austin in 1995 and hadn't
been working on PS/2 stuff for at least 2-3 years before that). The
ISA based machines (of which the PC330 was) came later.
So, was the Pentium you used in the 95 a P24T? I'm just trying to
get a handle on the order of things. The PS/2 guide:
http://www.lenovo.com/psref/pdf/ps2book.pdf
seems to say that all PS/2s used the P24T CPU, whose "official" Intel
release date was in 1995, whereas the original P5 Pentium was
available in 1993.
