They actually worked off of a wide (5 or 6 inches) magnetic tape on a single reel. This was presented to the system as a 3330V device type. When accessed, the robot arm loaded the tape cartridge from its cell inside the unit to a reader and staged it to 3350 from where it was accessed. De-staging was the reverse of the process.

You would specify the X, Y and Z coordinates of the cell you wanted to check. A fun trick was to make it tap the window and startle bystanders. > > I still have a bunch of the tape cartridges - they make excellent paperweights, and nobody knows what the heck they are. :-) > ------------------------------------ Hello! Makes sense. Last year I was at a seminar that your company threw on the subject of server sprawl and how to avoid it. They showed some excellent photos of their labs. One of them contained a representative of System Z, the presenter commented that the rep was there, of course he didn't actually come out and say why. I then asked in an a carefully phrased way about the participation in the division that supports external mass storage arrays. And since the last time I checked, that division does work with System Z, it made sense that the fellow was there. Everyone there found my way phrasing an interesting one. The presenter thought, and this is when the seminar ended, that I was a plant. Since I wasn't a spiderplant, I did indeed confirm who I was. He just stared at me as if I was backed up by the crowd from those movies. ----- Gregg C Levine [email protected] "This signature fought the Time Wars, time and again."
