Make up your mind, is it Tandem or is it mainframe? :-P

Come on Drew, no baiting...
You know that some people even call NT boxen "Midrange" computers...
Maybe the criteria is based on weight: If I can carry it - Personal Computer If I need a hand truck -- Midrange If I need a forklift -- Mainframe
Sounds about right to me. ;-j

Your criteria has to be modified
to take into account the reduction in size for hardware over the past decades. Many brands of mainframe are now small enough to be moved by hand cart. We really could get into quite a discussion just trying to define a midrange computer, if any company classifies their equipment as such nowadays.

Didja miss the ;-j
I remember the infinite thread discussion on what was a mainframe and don't want to go there again.
Call it what you want. Everyone (personal and corporate) has a definition of what is "mainframe", "midrange" and "personal".
Here, in just this data center, we have a IBM 3090 (?) mainframe with 36tb of data. And a "midrange" (over 500 Sun boxes) with 98tb of SAN data. And over 1400 NT (2003, 2000, NT) boxes with and unknown amount of storage.
How do I know what's a mainframe? The boss told me. ;-)

I did miss the ;-j
but you're stretching definitions to fit your own opinions.
"over 500 Sun boxes" does not equal a "midrange"; they're 500 INDIVIDUAL machines networked together to equal or beat a "midrange's" overall capabilities. And "1400 NT (2003, 2000, NT) boxes with and unknown amount of storage" are nothing more than just that - INDIVIDUAL units networked together. Cumulatively, their computing capacity easily tops one individual "midrange" computer, but that's understood.
So when you call up IBM and say, "Please send me a midrange computer" do you expect 200 units delivered to your door, or do you expect just ONE computer to be delivered?

Correction
The "over 500 Sun boxes" was not meant to imply one midrange. Each, loosely termed, application may have anywhere from 1 to 25 Sun boxes. Each Sun box cluster (even if only 1 box) is considered a midrange system.
The 1400 NT boxes are again either stand-alone or clustered to support applications. None of which are considered midrange. The USPS email system runs on NT boxes. (Special application prints out the email, puts a stamp on it and delivers in to your desktop ;-j )
If I were to call IBM for a midrange, I'd expect an iSeries (a.k.a. AS400).

How about basing it on the crash test?
If it doesn't crash, even if you set off a grenade in its innards; it's a mainframe.
If it does crash, but infrequently, it's midrange.
If crashes are common, it's personal.
And if crashes are routine, it's Windows.

Dunno about that
I've known people who've caused the mainframe to crash, requiring an IPL. It does take practice to get that "good" ;-j

I've only seen a midrange crash once.
Once, in 6 years, with an AS/400 - someone tried out a dodgy, seldom-used serial line debug program.

I've already made up my mind
and so did the company 13 years ago. I won't comment any further.

I don't have a horse in this race
jbrabeck's description above makes about as much sense as any other distinction I've heard.
