NO$X51 v1.5 is released. This project started back in 2001, at that time it's been emulating 80C31/80C51/P8xCE558 single-chip 8-bit microcontrollers, which didn't have too much pratical use as it didn't emulate whatever peripherals (like tape decks, washing machines, servo motors, temperature sensors, etc.). As of 2018 it turned into a fully fledged AMT630A emulator with 320x240 pixel TFT video, and standard 3KEY keypad input, allowing to create/debug AMT630A software...

NO$X51 Features:
The program includes CPU-emulation, assembler, disassembler, debugger, eeprom upload function, this wonderful package can be downloaded.
