"You can network most scopes these days

I searched for " floppy drive to LAN converter" didnt get any hits.
"Tektronix 547, now what??" a 547 never came with a floppy drive.
"There's a better chance that my jar of hair gel will spontaneously turn into a high speed WiFi ADC." havent heard of that one. have heard of porcine aviatrix though.
Hosts transmit and receive, are they hard wired to only see mass storage devices?
1998 HP and TEK scopes had floppy drives [ some of them]
I know Tek is/was notoriously cheap and stingy with the connectivity on their lower-end scopes, what scope model do you have? On the other hand, a scope in 1998 with a floppy would almost certainly have a serial port?
You can't connect two low-level devices like floppy controllers to each other that way. The floppy interface is at the level of sending stepper motor commands, sensing track zero, and having the bitstream from the heads. That's it.
The scope's computer expects to have 100% total control over the mechanism. When the scope writes to a floppy, it expects to spin up a piece of round plastic and pumps out a bit stream to the heads, with much participation from the OS to figure out where to write what.
It's quite low-level.
