Abstract: The functions of two virtual operating systems (e.g. S/370 VM, VSE or IX370 and S/88 OS) are merged into one physical system. Partner pairs of S/88 processors run the S/88 OS and handle the fault tolerant and single system image aspects of the system. One or more partner pairs of S/370 processors are coupled to corresponding S/88 processors directly and through the S/88 bus. Each S/370 processor is allocated form 1 to 16 megabytes of contiguous storage from the S/88 main storage. Each S/370 virtual operating system thinks its memory allocation starts at address 0, and it manages its memory through normal S/370 dynamic memory allocation and paging techniques. The S/370 is limit checked to prevent the S/370 from accessing S/88 memory space. The S/88 Operating System is the master over all system hardware and I/O devices. The S/88 processors across the S/370 address space in direct response to a S/88 application program so that the S/88 may move I/O data into the S/370 I/O buffers and process the S/370 I/O operations. The S/88 and S/370 peer processor pairs to execute their respective Operating Systems in a single system environment without significant rewriting of either operating system. Neither operating system is aware of the other operating system nor the other processor pairs.

Abstract: Opposite phase outputs of a pulse width modulator (12) are connected to a transformer (18) primary winding (N1, N2) with a centre tapping. Collectors of two transistors (22, 24) connected in phase, are connected to the input voltage source (V1). Two secondary windings (N3, N4; N5, N6) with opposite winding sense are connected by one end of the transistor (22, 24) bases, and by the other to the input of a filter (28). Emitters of transistors (22, 24) are connected to the tappings of secondary windings (N3-N6).
