262:. The System/32 processor utilized a vertical microcode format, with each microinstruction occupying 16 bits of control storage. There were 19 different microinstruction opcodes, however certain microinstructions could carry out different operations depending on which bits were set in the rest of the microinstruction, meaning that there were about 70 distinct operations available in total. An optional set of

The System/3 emulation performed poorly, which led IBM to implement performance critical parts of the SCP operating system directly in microcode. The later System/34 and System/36 systems addressed this problem by using two different processors - the System/32 CSP architecture was used exclusively
294:(MSP) which implemented the System/3 instruction set directly in hardware without microcode. The use of microcode to implement instruction set emulation as well as performance-critical operating system components had some influence on the design of the microcode layers in the later

Only one side of the 77-track floppy diskette was used. Each track held 26 128-byte sectors. An extended format was offered by IBM, and it permitted 512 bytes per sector. Even so, that came to an 8-inch floppy holding less than one third of a megabyte.
