au has a Qlogic SCSI adapter (might be onboard). 'a' has an Adaptec.
VGA card is also different.

Doesn't the 'au' have b-cache, whereas 'a' doesn't? 'a' model was sold as
an NT workstation.

The A was sold for NT only with an Adaptec AHA2940UW and a crappy Powerstorm
4D10T (NT only)

The AU shipped with a Qlogic QLA1040B (later ones came with QLogic on board)
and I believe the lowest config for VMS and Unix was the Powerstorm 3D30

I was under the impression that they all came with the 2mb cache module
plugged on the CPU board but I could be wrong

From what I have heard the Cache didn't make much difference when running NT
but made a huge difference when running Unix and VMS so the concept that it
didn't ship with the NT system makes sense

Oh - and also Bill Gates got a chunk of Royalty on the -A's sold !

When Tru64 v5.0 boots on my -A, it says "no b-cache". I would be interested
it obtaining one just to see if it makes any difference. But I don't know
if the -A can physically accept it.

The 500a can take an external cache module, so I assume the
433a also can ( the only difference should be the CPU ). If you open the box
up and look at the motherboard there's a space between the CPU ( with the
massive heat sink on it ) and the bank of memory connectors. You should see
an edge connector in this area ( running perpendicular to the memory
connectors ) - that's where the cache module goes.

Adding the cache module speeds some things up considerably
