Hi Gang - long time no type. I'm just looking for any insight or experience with a Sperry + Univac core memory card 90536-7128081-00 D Looks to be a later generation core module, lots of 14 pin dips with numbers like 7427, 7438, MC7524, 7502, 7503. card itself is 10.5" tall, 15" wide with 3 connectors along the bottom, each connector has 2 rows of 28 contacts (48 * 3 contacts in all) on .1" centers. This instance is in clean condition - I'd love to build an interface to it just for a crazy fun project. Chuck cswiger(a)widomaker.com
