\nI never had a HP65 but it was what my HP67 was based on and wow it looked like a great calculator.<\/p>\n

The keyboard layouts were very similar too.<\/p>\n

The f, f-1, and g keys became f, g, and h.<\/p>\n

There was extra writing added because the new g key was no longer labelled f-1 :
\n– on the HP65 f 9 was square root, f-1 9 was un-square root i.e. square
\n– on the HP67 f 9 was square root, g 9 was square
\nIt was no longer obvious so HP added x2<\/sup> next to the square root sign.<\/p>\n

The writing also moved from above their keys to below their keys.<\/p>\n

Aside from a few minor changes on the second row, the keys remained in familiar positions.<\/p>\n

You can see a HP67<\/a><\/p>\n

So, why did people upgrade from the HP65 to the HP67?<\/p>\n

There were lots of really good things about the HP67 and just as many reasons. A couple of obvious ones were: more memory and bigger programs. But, for many, these weren’t reasons to ditch the great HP65 – merely reasons to get a HP67 too.<\/p>\n","protected":false},"excerpt":{"rendered":"
