Those days
fooling with the hardware were fun, but now
that there are emulators that can run about 100 times
the speed of a PDP-11/73, for an RT-11 software addict
like myself, the hardware has become much less important.
Doesn't work for me. Sims are useful but the fastest PC I have
is a 1g celeron. They aren't that fast and often a lot less
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.
reliable as the OS supporting them can be cranky.
I still have two xerox paper boxes full of Qbus cards, hardware
is easy.
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.
