and its assembler startu code
https://pastebin.com/3rG2eiWD

i found this on an old dvd that was part of company assignments. it seems to be a demo of multicore use in plain dos.
im not a programmerso i dont know where to post this the nerd way but it contained a binary and it at least does not crash and prints a heartbeat.
enjoy
