I have acquired a Measurement Systems DM6400 64k dynamic memory card. I need to find the manual for the card. Searches on the Internet have turned up nothing.

What I have learned so far is that Measurement Systems made a DM6400 non-bank select card and a DMB6400 bank select card. The DMB6400 manual describes several different configurations for the card with switches and headers to allow the card to work with several different processor cards. There are, of course, differences in switches and headers between the cards; so, I can't use the DMB6400 manual. Just plugging the card into my test setup gets no results.

My test setup consists of an Ithaca Intersystems series II MPU80 processor with a simple monitor program and a series II VIO I/O card plus whatever memory I am trying to test. The DMB6400 manual mentions an Ithaca Intersystems cpu as one of the possible configuration options so I am hoping that the DM6400 can also be configured for it. I am aware that the reference to the Intersystems cpu may be referring to a series I cpu and not a series II. I am hoping that will be clarified in the DM6400 manual.

Thanks,
Phillip

Thanks for the response John. However, as I stated initially, there are differences between the DM6400 and DMB6400 boards. There are several more switches on the DMB6400, so trying to use that manual to configure the DM6400 would seem to be fruitless. But if I am missing something, please let me know.
