Hewlett Packard HP-85 Computer

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

Inside of its lower compartment the Hewlett Packard 85 is covered with a nice HP cover.

I have just aquired a huge collection of HP-85 machines and rom pacs, software, hardware and manuals of all types. I have not even begun to sort through it all yet. If you have a specific item you need please contact me at the above email address. I have software on 5.25 disc, disc pacs, new tape cartridges never opened and a bunch of other stuff I will be sorting through in the next weeks including cables and interfaces.

These were called calculators as a sales/marketing ploy. Buyers were having trouble getting purchases for computers approved. However, companies more easily allowed for the purchases of 'calculators'.We actually still use am HP-85 to run a piece of equipment at our facility. Very reliable after 24+ years of service.
