The software question is important, may make older
equipment "unsuitable" even if the box itself is capable.
I got a lot of mileage off the HP8561E that I pulled off
the red tag ("uneconomical to repair") shelf of my last
employer's headquarters lab, to try and fix up for my
remote office. Turned out to need one video trim pot
tweaked (deep inside the multiple planes of TTL series
logic boards) and I got a 6GHz classic specAn for nada.
But hardcopy and data transfer, got no clue.
