The HP-86 contained all the features of the HP-85 but was not portable. A user had the option of using an external monitor via a built-in interface. |
The HP-86 personal computer
offered users more options and expandability than the HP-85,
which had been introduced two years earlier. In addition to an interface
for an external monitor, the HP-86
also had built-in interfaces for two HP
9130A disc drives and a Centronics-compatible printer for additional
system configurations. For video output, users had the choice of
a 9-inch or 12-inch monitor, both of which were available from HP.
The HP-86 came standard with
64K ROM, which was expandable to 576K, and 48K RAM.
The amount of RAM could be expanded with the HP Model 82900A CP/M
System Module, which contained an additional a 64K RAM and plugged
into the back panel of the HP-86. Its addition allowed the use of
software designed for the CP/M operating system.
