Well, ok, if your list was intended as a "first
VAX" only list, then
That is what I believe the OP was asking for,
It's not exactly like a workstation or a PC.
That is surely a Good Thing :-)
The 6000 series are quite big cabinets and as a
first VAX it's hard for me to
see the great advantage over a microVAX or a VAXstation.
They are small compared to a VAX-11/780. The 11/782 would become very big, and use even more
power. Not that an
11/780 are small to start with, but we're talking about roughly doubling
the size and power consumption here... Not to mention being a very odd
Yes, it's close to being a pair of 11/780s running in parallel.
machine from a multiprocessor point of view as well.
Not something I
would recommend unless you are seriously interested in that specific
machine.
Nor would I, but if I had the space (I don't!) I would love one...
.
The 11/730 and 11/725 are probably among the last
machines I would ever
Sure it's slow, and there is a major design misfeature -- I mean who seriously uses
DRAM as a control store, and then has to halt the CPU to refresh it every few ms. But
IMHO fitting the complete VAX CPU onto 3 hex boards using standard ICs (apart from
the memory ECC which used the same gate arrays as the 11/750) is an interesting, at
least, bit of work.
want to have. We all have different dreams... The 8650
is sweet. I could
possibly like a 9000 even more...
As I keep on saying, and I hope the OP considers this, the ideal VAX depends
on who you are. As I want to get inside the CPU with a logic analyser, there are
really only 2 series for me to consider. One large, the other slow. As I am short
of space and not time it is obvious what I looked for.
