No. The original disk for the altair before they became Pertec Computers
was an 8" system using two boards of TTL. I know I built three of them in
that era and debugged a few more. All if the later Pertec machines with
minifloppies had a board that used a 1771 plus a raft of ttl.
I might add the Pertec controller was sold before the Pertec aquired MITS.
