Instead of turning a clock into a vintage Mac, I turned a vintage Mac into a clock!, I though it would be fun given its #MARCHintosh The program can be downloaded here: https://github.com/retrotheory/BigMaclock

It supports US/EU month day order AM/PM, Invert display, 'grey' background and alarm function, it also has dynamic sizing so it will look correct on bigger screens

Once upon a time, in a far away land called Compaq Portable III, there were 3 tantalum capacitors that thought they were resistors. This did not bode well for the silly caps,and two lost their heads. Once replaced , the land of Compaq Portable III was happy ever after. THE END
