DOS

Brothers! Tell me, dark, where on the Pentagone you can find a DOS signal, otherwise
SD is tired of cracking when the floppy drive is working.

The signal that connects TR-DOS (goes to ROM) you invert and get what
you need (in fact, it is on the controller and is usually formed on TM2),
mix according to the OR scheme with /IORQ and feed it to all external devices, except
the drive controller, i.e. It turns out that all the peripherals are turned off while
accessing the controller.

PS. I can’t describe it in more detail, because... I have Leningrad-1
