Folks, I have three boards with no clues of origin or schematics. Two of them have a reed relay, 8 transistors, 3x 7400, 1x 7410 and 1x 7476, coded 90461. The third one has 9 transistors and one UA747, coded 90406 I also got a couple of KR50 mechanisms, so it will be nice to know how to drive the magnets to adjust the force. Any hints welcome! jon, ea2sn / ae2sn _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/listinfo/tentec |
