WHICH specs?

If you're asking about the disk format:
They use a similar logical structure with different parameters; mutually
incompatible, but same idea for DIR structures. (I use the same
subroutine for both, with different variables)
Both use 300 oerstedt ("360K") diskettes.

If you are asking whether you can install a second (or replace
original) drive:
YES.
It is an "industry standard" flopy drive. You need to use a drive that is
300 RPM, and can properly handle 250K data transfer rate ("180K" or
"360K"), such as Shugart/Matsushita/Panasonic 455, Teac 55B, etc.
Only thing to watch for would be termination and drive select.
