Happily for me I don't do stuff

I just about remember the SystemPro machines. One of my bigger clients
in my first job got one, but they hired a full-time guy
And of course, if your server dies, then the array can be mounted on
any other box with the same OS and you can retrieve data from it --
which is far more difficult if a hardware RAID controller dies, in
which case you might need the same firmware revision etc., and
possibly onboard controller

Funny story about that - I just setup a Systempro XL at home to play with. It
is fully decked out w/ dual processor 50MHZ 486s
ATA? That long ago?
Sorry, IDE like. Forgot the terminology. You could put 4 drives on a
controller, then two controllers per unit (EISA was cool).
Possible but unusual in a server, I would have thought.
What OS, just out of interest?
I think it was SCO Unix.
A single box? Oh dear.

I have never used a SW RAID solution (except for a RAID 0 on Win2K3 for the
boot drive) and have used HW
Now in terms of the most MANLY system I worked on, that would be the
NCR3550 we had at the IEEE Computer Society. When I arrived in 1993 it
had been donated, but was doing nothing with 4 486 CPUs in it and a
weird copy of AT unix. I took one look at the 256 bit interleaved
memory architecture

MS LanMan was Microsoft's networking OS of choice before NT. The base OS I
believe was based on MS OS/2 1.31.
Wiki has some more info: en.wikipedia.org/wiki/LAN_Manager
I have a copy of it somewhere. Here is a picture of the

Hi all --
Picked up a board advertised as a "4mb memory board" for a VAX-11/750.
It's made by Dataram and I'm unsure of the model number, based on photos of
it. I just noticed that rather than being a hex-height board that goes in
the memory backplane, it looks like a board that goes in the main

Obviously now you need to pick up a VAX 8000 system.
That does seem to be the most logical next step, yes :).

I think I have a load board for one somewhere ... No idea
