The HP-85 was a logical extension of the HP Calculator line that added a bigger screen and more storage to stronger calculating ability.
By including BASIC with the machine they also added programmability. With the addition of "option drawers" the machine was as expandable as any other on the market.
The HP-85 in my collection came to me in a custom built box that easily outweighs the machine, but protects it well.
The case has two sections. The upper opening gives access to storage for tapes, documentation and spare paper
There is a lot of documentation. This is only a small part of it.
Inside of its lower compartment the Hewlett Packard 85 is covered with a nice HP cover.
