Bochs (pronounced "box") is a portable IA-32 and x86-64 IBM PC compatible emulator and debugger mostly written in C++ and distributed as free software under the GNU Lesser General Public License. It supports emulation of the processor(s) (including protected mode ), memory, disks, display, Ethernet , BIOS and common hardware peripherals of PCs .
It was a single-chip implementation of the eight-chip POWER2, integrating 15 million transistors on a 335 mm 2 die manufactured in IBM's 0.29 μm five-layer metal CMOS-6S process. The first version ran at 120 or 135 MHz, nearly twice as fast as the POWER2 at 71.5 MHz, with the memory and I/O buses running at half speed to support the higher ...
Some VM/emulator apps have a fixed set of OS's or applications that can be supported. Since Android 8 and later versions of Android, some of these apps have been reporting issues as Google has heightened the security of file-access permissions on newer versions of Android. Some apps have difficulties or have lost access to SD card.
Apps wanting to access files or folders outside that on the SD card, are required to use Android's own system file selector. [14] Due to this limitation, guest OSes running on, emulation, platform virtualization, or compatibility apps are no longer allowed to access files outside of their own SD card Sandbox.

In 1974 IBM started a project to build a telephone switching computer that required, for the time, immense computational power. Since the application was comparably simple, this machine would need only to perform I/O, branches, add register-register, move data between registers and memory, and would have no need for special instructions to perform heavy arithmetic.
