I found this in the 9000 series 300 Configuration Reference Manual:

The 9885M/S are 500 Kbyte 8-in flexible Disc drives. The masster drives are
GPIO interfaced. THey are no longer supplied, having been replaced by the
9895A.

Interface and Command set GPIO, unique
Seek time 267 ms average
Average Latency 83.3 ms
Transfer Rate 23 Kbytes/sec.
Formatted Capacity 499200 (per flex medium)
Bytes per sector 256
Sectors per Track 30
Tracks per surface 67 (plus spares)
Surfaces per drive 1
Format options none
Media 9164-0105 (box of 10)

There are some more details of interfacing to the series 300 Basic and
Pascal systems using a 98622A Option 002 GPIO interface.

I don't have easy access to scan anything; there is more information about
the 9895A in the book.

I have a 9885M, but no manual for it.
