Data entry man at gas station has been taking inventory for 30 years

He can type numbers faster than I can read them!

Incredible data entry

I slowmoed down and calculated about 80+ WPM at 5 per word. Although it's all numbers so even faster. He said he had been doing this for 30 years! People that came into store would stop in their tracks and watch this guy with their jaw dropped. At first I thought is this for real and it was!

I couldn't figure out what make that portable data entry terminal is. I suspect it's quite old, but my shame is complete. Anyone know what model it is?
