yesterday I rescued this old relic just before some people here at work was preparing to through it out. I had not seen it before, (or anything like it for that matter), but thought it'd be fun to see if I could get it working again. After an hour or so of tinkering it has fired to life. I have many questions. What is the vintage of this machine? It seems to basically work but it seems to have some sort of number in a shift register or something as i can not figure out how to clear it. If I add 100+100 then press total I'll get a huge number. Any chance of someone forwarding an instruction manual? Thanks, Jeff
