I copied Io.sys, Msdos.sys, and command.com to drive A:, but the machine still won't boot.

IO。SYS needs to be copied into specific sectors on the floppy; just copying it over is not enough. Use SYS。COM to make a boot disk. MSDOS really only needs these 3 files to boot.

For DOS systems like PC-DOS, ROM-DOS, and PTS-DOS, the three required files are IBMBIO.COM, IBMDOS.COM, and COMMAND.COM.
