Do you not have the manual? The M980 manual is on bitsavers.

I have the slightly earlier M900 model, by the front panel they're quite similar. I've used it for programming 2716s, although it's been a few years. IIRC it's an ASCII-format protocol for RS-232 serial, so you just have to have a terminal program you can dump a file through.

Be careful about the hardware communications interfaces. The 9-pin D connector labeled 'serial interface' is not the RS-232 serial standard. There were several firmware and hardware communication options. Do you have the pro-log adapter, or are you making an assumption about what's there?  My unit had the RS-232/serial firmware option but was missing the RS-232 adapter, so I had to build one (can be done with just a MAX232 IC).
