[1] MIKBUG was distributed by Motorola in 1974[2] on a 1 K ROM chip part number MCM6830L7.
It requires 128 bytes of random-access memory for operation.
It assumes the presence of a terminal that the user will use to issue commands.
Callable functions include input and output of a character on the terminal, input and output of a byte in hexadecimal format, print a string terminated by EOT, and terminate the current program and return control to MIKBUG.
Listings of MIKBUG and MINIBUG monitors are available online.
