monsonite / SIMPL_04_19
Created April 20, 2019 14:19
// SIMPL - A Serial Interpreted Minimal Programming Language
// Inspired by Txtzyme - by Ward Cunningham
// This version runs on Maker Uno with speaker on Digital 8
// SIMPL allows new words to be defined by preceding them with colon : (Like Forth)
// New words use CAPITALS - so 26 words are possible in the vocabulary
// Words A-F have been predefined as musical tones - but you can write over them
// A word can be a maximum of 48 characters long
// Type ? to get a list off all defined words
#define bufRead(addr) (*(unsigned char *)(addr))

SIMPL- with EDSAC virtual machine grafted in!
// SIMPL Interpreter for MSP430 Launchpad MSP430G2553 - with EDSAC Simulator grafted on!
// An experiment in minimal computing simulated on an MSP430 launchpad
// Really a dreadful hack, done on a very hot day in Greece - I'll get my coat.......
// SIMPL provides a shell to allow basic communications with EDSAC simulator
// Teraterm is a convenient means of sending files to the SIMPL machine

Test code for Arduino Z80 ROM Emulator
//--------------------------------------------------------------------------------------------
// ROMulator 3
// Compiled using Arduino 1.65 or later
// A customised vesrion of SIMPL to allow RAM and Z80 bus to be exercised using SIMPL.
// Address is st using a pair of 74HC595 shift registers
// Data is passed through a 74HC245 bi-directional bugger
// TRISTATE line when raised isolates the address and data registers from the Z80 bus - allowing it to run
