XTF-A The XTF-A front panel can be obtained making very small changes to the Hit Buffer front panel. The two holes for the HB central and the bottom connectors must be made larger to host the two Honda L1 Trigger connectors. The position of the lower edge and of the left edge of the connectors are kept constant, with the upper edge and the right edge shifted due to the larger size of the Honda connectors. Hit Buffer XTF-A Upper edge of the bottom connector: 2.870 3.625 Horizontal width of the bottom connector: 0.300 0.323 Position of the DS led: 2.830 3.585 NO HOLD LED Upper edge of the central connector: 7.170 7.915 Horizontal width of the central connector: 0.300 0.323 Position of the DS led: 7.130 7.875 NO HOLD LED Everything else must not be changed. We expect to build 3 XTF-A boards. XTF-B: The XTF-B front panel is almost equal to the merger: Modifications: a) Only 1 LED on the top (PWR) b) Only 2 LEDS on the bottom (BRD 0/1) aligned horizontally like the AM board ones c) No hole for the Test Point d) The name for the 6 connectors is: OUT 1, OUT 2, OUT 3, OUT 4, OUT 5, OUT 6 We expect to build 5 XTF-B boards. By the way, I am not sure if we asked Chicago to buy some Honda connectors for the XTF-A board. Do you remember anything about this order ? Thanks, Simone
