The H11 is one of the first 16-bit personal computers, at a list price of US$1,295,[2] (equivalent to $6,050 in 2023) but it also requires at least a computer terminal and some form of storage to make it useful.
[3] The H11 featured:[4] Initial memory limitations restrict the selection of system software, but the system RAM can be expanded to 32 kWords * 16 bit.
Many PDP-11 operating systems and programs run without trouble.
The system will also work with most DEC PDP-11 equipment, including many Q-bus compatible peripherals.
