Yes, just so. I learned about that one decades ago.

Modern technology is not only cheaper, but it's faster and uses less
power--and is usually more flexible.
I suspect that a PDP-11 in FPGA is quite a bit more reliable than the
real thing--and when you're done you have a nice abstract description of
the hardware in VHDL format.
And yes, I have a pile of old CMOS/ECL/TTL logic.
Remember when CMOS logic was new-- +15V Vdd and 1MHz top speed?
