  Hello all.  I looking around for a Logic Analyzer for
doing (mostly) DEC
 QBus/UniBus stuff.  Being the way I am I want something with enough lines
 to handle the most of the signals so I'm guessing something with roughly
 80-ish channels.  I think that lets out all/most of the USB based LA.  I've
 looked around and it seems the the HP/Agilent 16700 series (16700B/16702B)
 are probably what I want.  I've also seen the 1670G which also seems quite
 doable.  I've seen a lot of posts at the EEVblog and it seems I missed
 possibly the golden age of 16700 LA by a few years price-wise.
 What I'm wondering is if there is something specific I should be looking
 for, or opinions on which LA is more suitable.  Or even if there is a
 different make of LA to look for.
 Thanks in advance for your help

Where are you located? That can have a large impact on the cost of
acquiring a large 16700-series logic analyzer. For example, I have more of
those than I need in the Seattle area. A local deal might work out well,
but if shipping is involved that can quickly get too expensive.
If bench space is limited, a 1670G takes up a lot less, and is completely
self contained and easier to move around and set up. On the other hand, a
16700-series is more flexible, and if you have space to set up an external
monitor you can see a lot more data on the screen at the same time without
scrolling around.
