emulators

Let the earth be down to you, All...

Comrades, could you recommend a good Spectrum emulator?
One that would work with Sinclair disks. And then there are about 100 floppy disks with toys for the good old ZX, I wanted to remember the old days when Pentagon 2 was the ultimate dream... :) And, alas, there is no software... :( There was some kind of emulator, but it didn’t work with disks, it was necessary to format the disk on it, and
then on Sinclair itself, rewrite what you need onto it... And where can I take a live Spectrum in our
difficult post-perestroika time? :) Mine is long gone... :( Someone help with advice, or, even better, with the program itself...
The echoes of my gratitude will echo throughout the echo. :)

You are welcome, All. Welcome to die. With beast wishes, - Andrew...
