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.
Specs
- 24 bit address space for a maximum 16MB of RAM (later models: 31 bits)
- 16x32-bit control registers, in supervisor mode only
- 16x32-bit general purpose registers
- 4x64-bit floating point registers (could be used as 2x128-bit floating point registers)
Games
Well thankfully there seems to have been some games....
Emulation
The 370 can be emulated by the following emulators:
