My Ampex card is a not-very dense full-length card with LSTTL and one 2732 EPROM. Connection is made by a 25-position dual row (0.1) header poking through the rear bracket. Probably cheaper than any D-sub or "Centronics" type connector of the same pincount. IIRC, the PC Megastore also included a streaming 1/4" tape drive in the same box. According to Infoworld, the MSRP was about $3775. Disks weren't cheap in 1985. Ampex used the "Megastore" tag on a bunch of things, including their memory-as-a-fixed-disk for minicomputers. --Chuck
