Author Topic: Ball and Disc Intergtrator as a variable speed rewind Paul G. Thompson The Weenie Man Posts: 4718 From: Mount Vernon WA USA Registered: Nov 2000 posted 01-10-2003 04:22 PM                     Anyone try to make one of these? Do you think it is practical? Seems to me if it worked in electro-mechanical computers 45 years ago, it should work today. Getting highly polished hardened steel disks could be expensive, though. But that could be the only major down side except for the movable ball carriage. What do you think?  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 01-10-2003 07:57 PM                     Paul, Do you mean the Ball and Disk integrater as used in the MK1 fiire control computer but adapted to a rewind??? Are you related to my Uncle Rube? Mark  |  IP: Logged Paul G. Thompson The Weenie Man Posts: 4718 From: Mount Vernon WA USA Registered: Nov 2000 posted 01-10-2003 08:26 PM                     Yup. I forgot what the CP designation was, but it was the BDC of the old ASB-1A the Navy A-3D airplanes had.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 01-11-2003 04:20 PM                     Yea, there's a whole web site on that...now if I can just find it again.........it also covered the MK1 computer in great detail.
