They were remote power monitoring stations, kind of like an electric meter but with a bubble memory drive with a bubble memory cart plugged into it. We got lots of carts, too. This was about 10 years ago. They came from the State of Washington IIRC. I was surprised to see them. Before that the only bubble stuff we had seen came from Intel. IIRC they were of Japanese mfg., I don't remember if they were Fujitsu but it is possible. They used a removable 128K memory module, about 3/4X1X2 inches in size that plugs in and out of a socket on the drive. They were remote power loggers. Someone showed up, pulled the bubble cart, replaced it with another and took the just pulled one down to the office and read it. Paxton Astoria, OR
