The S/32 has two storages:

- Control Storage:
This storage is 4 kiloword large and contains micro-instructions for the S/3
instruction set emulator and the IOS. (The S/32 CPU is hardwired, not
micro-coded)
These micro-instructions have all a fixed length of 16 bits.


Have you been able to successfully extract the microcode records from a S/32 
IPL or diagnostic floppy?

I noticed that the first track is very different, with very long sectors 
compared to the
rest of the disk.
