Post subject: | Burroughs B5500 in the browser |
. Emulator in the browser. (You would need to read up on how to operate the machine!) It's a very interesting machine from 1962. Brochure here. From the notes: Quote: The Burroughs B5500 was an innovative computer system. Released first as the B5000 in 1962 and then, with minor improvements and a new disk subsystem, re-released as the B5500 in 1964, its design was a radical departure from other commercial systems of the day. Many of the concepts that it embodied were being worked on and implemented by others around the same time, but it is difficult to think of another system that pulled so many new concepts together and made them work so well in a commercially-successful product:
Variable-length memory segments Hardware bounds checking Unified integer/floating-point numeric format Designed for and programmed exclusively in higher-level languages Designed for and managed by a sophisticated operating system, the Master Control Program, or MCP Multi-programming (multiple tasks sharing the same processor) Multi-processing (multiple physical processors sharing common memory and I/O) Automatic memory allocation and address relocation Automatic memory segment overlay (what we now call virtual memory) Use of labeled file media and automatic assignment of labeled file media to requesting programs (what we now call automatic volume recognition) More photos and some videos: http://www.retrocomputingtasmania.com/h ... ughs-b5500 |
