Hi folks,
Looking for documentation on the DATARAM DR-118 16Kx12 core memory for PDP-8/e. I have
the documentation on the DR-118A which is for the PDP-8/a. It is probably similar, but
would love to find the right version.
Anyone have such thing?
Thanks
Eugene

I don't have an answer for you only an additional question.
Since the E came out before the A and DATARAM made a board for the E, and
quad boards from the E would work perfectly in the A why would you make a
board specifically for the A? Did they make a Hex board version of it for
the A? Was the E a two board set?
Hope you find the documentation.

From what I have seen, yes. There is a Hex version of
this board for the 8/A. the product for the E was a 2 board set. Each pair of boards had
16k X 12 bit. So two pair of boards are required. I have two pair but have some stuck bits
I need to figure out.
