The System/370 continued the tradition of the prior System/360 by expanding the instruction set, and adding the new ability of virtualization. It ran a variety of software, such as MVS, and the newer VM/370.
The System/370 was supplanted by the S/390.
- Sixteen 32-bit control registers, in supervisor mode only
- Sixteen 32-bit general purpose registers
- Four 64-bit floating point registers (could be paired as two 128-bit floating point registers)
- 24 bit address space for a maximum 16MB of RAM (later models: 31 bits)
Well thankfully there seems to have been some games....
The 370 can be emulated by the following emulators:
