Nor me. My festest PC is this much-hacked 5170. A PDP11/03 would easily 
beat said PC (running a PDP11 emulotr). As I have a real 11/44 and 11/45 
available,. it's obvious which I'd use.

That's apart from the fact that I am primarily a hardware person. I want 
to be able to connect a logic analyser to the ALU outputs, single-step 
the microcode, and so on.

Ditto, but Unibus, if you see what I mean. I got a load of Unibus comms 
stuff in a clearout (DMC11s, DMR11s, KMC11), a DB11 repeater, DW11-B Qbus 
translator, most of the common-ish serial cards and disk controllers, and 
so on.
