Does it have a serial interface and memory. In which case it was probably programmed in Assembler. 
When I started with 6800 board and 256 bytes of memory, and toggle switches to load it I used to hand assemble the programs to get the hex/binary.
I soon got bored of the toggle switches and built a little box with an old calculator keyboard and display and some TTL so I could enter data quickly.
