Reminds me a bit of a HP mainframe I was an operator on in the mid 80s. We had essentially a paper/typewriter style terminal so that it would record all input and output direct to continuous paper that would be saved for auditing if needed.
Type a command, read your book until you heard it print a response, go read the response and do the next step. Repeat.
I had similar on a VAX 11/750. The LA120 DECwriter was connected to the system via a serial port mux adapter.
One night the mux adapter glitched and reset itself back to defaults, which turned on local echo, so it reflected 'login:' back to the VAX, which responded with the password prompt.
This prompt was reflected too, giving an incorrect password response...which was reflected back to a new login prompt...etc..rinse, repeat all night.
Everything was printed on the LA120 until the fanfold paper ran out.
I came in the next day and could not see the LA120 due to the amount of paper on top of it.
Type a command, read your book until you heard it print a response, go read the response and do the next step. Repeat.
