But I'm pretty sure it was designed by Commodore.
The Apple Disk ][ was also made by Alps after a while, and it was known for being a very good drive.
FWIW, my first computer was an Apple //c, 1MHz 65C02, 128 kiB RAM, and ONE floppy drive. The keyboard was shorted out, making typing an adventure, and the floppy controller wouldn't work right with a second drive plugged in (the internal drive would drastically speed up, and the external drive would run at the correct speed, but constantly run.)
Oh, and I first used it in 1991.
