Nope, it's a simple cage with a 4-slot backplane with extended bolts that
'plugs in' to a bigger enclosure, which might be the brown box you're
talking about - I might have just the innards. Any clues on what it actually

Not a problem, assuming either this MVI or my MVII still work. Since I got
them from a retired DEC engineer they must be field circus diags; from what
I remember the customer ones were only 2 disks (format being one of them
IIRC) whereas these ones are upwards of 6 or 7 disks. There's at least 6
sets of them too.

I'm most interested at seeing what version of VMS is on the MV I......It's
got over a meg of memory so it could be 4.5 or 4.6. 5.x wouldn't run with
less than 4 would it?

Looks about right, it's just the labelling that's confusing since they've
got the required, optional and library sets with different 'total' numbers,
ie 12/32, 13/32 etc when there's clearly not 32 disks in the set.

heh! I'm desperately trying to remember if the BA123 box I thought was my
MVII (well, it was the company's back in the late 80s) was actually upgraded
by me to be an MV 3400 or not. I know I got a BA213 (?) 'real' MV3400 cab to
house the boards in its later life but I can't remember if I restored the
MVII to its former glory.....grr....I know exactly where the cab is so I'll

As an aside the MVII back then ended up being called 'fruit' because it was
paired with a 3100-10 called 'nut' to form the 'fruit&nut cluster' :) The
MVII was replaced with a 3100-40 (whose motherboard I've still got ) called
'dough'. You can guess the rest.

No bother.

I'll make it a priority once I've finished building the cupboards in the
alcoves in the living room :) Bloody B&Q [1] with their warping
