Hewlett Packard

HP-85 Computer

tested 

 (see pics)

some yellowing due to age

 good component condition 

The HP-85 came in versions with 16K or 32K of user program RAM. The HP-85B which was introduced featured the Mass Storage and I/O ROMs built-in. For faster access, an electronic disc was also included in the B version. This disc held 32K bytes (in addition to the 32K of main memory) as shipped but could be expanded up to 544K bytes with plug-in modules. The Series 80s allowed subroutines to be executed from mass storage devices so the electronic disk made it possible to write large programs that ran quickly. 

A great addition to your vintage computer collection.
