Here are some of the specs for the 251 and 296.  These are from a Seagate rag
that they will probably send to anyone describing most all of their products.
It is Seagate Publication #1000 (I have Rev G, Aug 15, 88).  Try calling
800-468-DISC or 408-438-6550.  Personally though I am partial to Conner
Peripherals, 408-433-3340, who have 20, 40, 100, & 200 meg drives.
