The 3B2 was a small, multi-user UNIX computer introduced in 1984 by AT&T. It was the primary porting platform for UNIX System V Release 3, but has since faded into obscurity. I built a full system emulator to allow running unmodified UNIX SVR3 software for historical preservation. This project involved a tremendous amount of reverse engineering both hardware and software, as internals documentation was unavailable. Additionally, WE32100 assembler and disassemblers had to be written from scratch. It is released as part of the SIMH historical computer emulation framework.
Symon is an 8-bit system emulator, including full emulation of the 6502 CPU, 6551 ACIA, 6522 PIA, 6525 CRT controller, RAM, and ROM. It is released under the MIT Open Source license.
