Avail: 50-pin cables/rack-panel/connectors for unknown system

Hi, (hoping this version makes it past the classiccmp filter :) Free to any home: (pick up in Cupertino, or pay shipping) two 5 meter (?) cables, with female 50 pin AMP connectors on both ends (three rows of holes: 17, 16, 17). The cables have tags reading: 422-0018-018 REV C RMH one 19" panel (about 1.5" high) with two male 60 pin connectors (matching the ones on the cables). These two connectors are wired to two long ribbon cables (3 meters?) that both end in 50 pin card connectors of some kind. The male connectors on the panel are labelled J1A and J1B. These were bundled into a surplus purchase, and have absolutely no connection with the computer I got! thanks, Stan Sieler sieler(a)allegro.com
