[vcf-midatlantic] Info Needed: DATARAM DR-111 PDP-11 Unibus 16KW Core Memory

Looking for any information and/or documentation on DATARAM DR-111 (assembly 61101) 16Kx16 core memory boards for the Unibus. I've got four in unknown condition, one with a clearly destroyed 8T37. I have a large format scanner with ADF and can digitize print sets if necessary. Thanks, Jonathan
