One of the outstanding features of the SWTPC 6800 Microprocessor/System is its use of Motorola's Mikbug firmware package stored in the MCM6830L7 ROM. It is through the software stored in this ROM that the user may use the control terminal to initiate various functions such-as load programs, execute programs, dump programs and print or change the contents of the CPU registers. Motorola's Engineering Note 100 describes in detail the operation of the Mikbug ROM.
