NorthStar - 48k Dynamic RAM
Board
There were three versions of the HRAM
board: The HRAM-64 with 64K bytes, HRAM-48 with 48K bytes, and HRAM-32 with 32K
bytes. The only significant difference between these boards is the amount of
memory they contain. All three versions incorporate parity error checking and
bank switching capabilities.

There were slight jumper differences
between the boards, but the one manual was used for all 3 boards.
The manual can be obtained
here.
