I think the spring you mean is located at roughly where the two 'arms' of the levers holding the heads meet. It's there with some red glop on one end and appears to pass from one side of the lever assembly to the other. I can see the upper end of the spring.. but not the lower end. Will have to find an inspection mirror to peer underneath. The upper end has some red glop on it. I'm a little nervous about removing the head assembly. Without an alignment disk and software to run it, I doubt I'd get the heads back to where I could read 'em. Thank you for posting the jumper list. Very much appreciated. Regards, Mark

While I'm on the subject, I'm trying to get a few drives to work on a Big Board II a friend gave me. He gave me four 8" drives, 3 SS, one DS. Two are Memorex SS which don't work at all, one is a SS Siemens which works perfectly, and a DS Siemens which sorta works. I mean sorta because it does not step backward nor does it home when needed. I have the strangest feeling that the drive went south somewhere and I don't know what to look for. But, like I said, I have a couple of other 8" floppies which do indeed work, one a Shugart SA-851, and a Qume Qumetrak 842. I'd like to know how to jumper these two buggers so they could work with the Big Board II aside from drive select which any idot who knows what he/she/it/other is doing. I have some docs, and it doesn't say a thing how to jumper the drives. Also, does anyone know of software for the Big Board? From what I understand, it enjoyed a great deal of popularity in the Netherlands, and they wrote lots of stuff for it. Many, MANY thanks in advance.
