This is a COCO TANDY Computer fake interface emulator for Z80. I have fully invented and programmed it from the Coco Tandy interface. I have implemented some functions: MEM to show fake ram memory : ). NEW enter, to clear screen CLS 1 TO CLS 7 enter, to change the 7 border color CLS enter, to come back to green Now you can play 7 notes from PLAY STR1 TO PLAY STR7 enter ,to play a music note SONG to play a song. if you write 10 PRINT HELLO WORLD enter, you get a BASIC answer. I have added a real Calculator. you can call it writing CALCULATOR inside the OS. There are some mathematical functions +, -, *, / ,^,%,TAN,COS,SIN. you can call them at the operand entry. Added a functional COPY - PASTE of my invention function to use it write COPY enter, then the words you want to paste and PASTE enter. writing PASTE 2 you can repeat the PASTE every time you want. Added a Guessing little game inside the emulator write GUESS1000 enter, then yes in short letter to play. Added a Chronograph that counts numbers from 0 to a number set by user. Write KRONO to call the Chronograph application then write a number then return, after the count you will be again in the OS interface ready to write another command or letter. Added a Reset keystroke to come back to the initial screen. the keystroke is RESET * enter.
