This article contains notes on installation of a Roger Beep inside an Icom IC910 transceiver.
This is a proposed solution, I have not performed this modification.
CAVEAT: Any modifications that you make to your transceiver are entirely your own responsibility. Owen Duffy takes no responsibility for the accuracy of this article, or for the outcome of your modifications. Modification of a transceiver may have implications for original warranty.

Fig 2 shows the module installed in an IC910.
Fig 3 shows a candidate for connection of the Roger Beep module near the back of the MIC jack.
The proposed modification is to cut the PTT track near J6 on the display board (see Fig 3), and to connect the RB PTTin and PTTout wires each side of the track cut (PTTin goes to the J6 side of the cut, and PTTout to the L5 side of the cut). The rest of the RB connections can be made to J6 connections to the display board (RB ground to J6 pin 8).
Before finally tucking the module into the transceiver:
