And regarding the location of the first store, 98 Carlton Gore Road, Newmarket, Auckland. It is likely the phone number is no longer good, so I'll keep that to myself - even though the copy of the '82 catalog I uploaded and have linked to elsewhere may have all that for you. I have here the brochure that was printed with the advertising blurb and specifications, the company listed is Compucation Systems in Tauranga. Where Dad bought our machine all those years ago. So looks like it took them a year or more to get through-out the country.

I've referenced in another post, but I recall Terry has a copy on his website too.
