Yes, this is very scientific The two cameras are connected to the electronics by only quite fragile flat wires, so best to keep the tape that I put. Once you have the frame grabber card, you need to connect the camera to the card with the cable that @tboysen sent you. Then find a way to power the camera with +/- 15VDC and 5VDC (about 0.5-1 Amper each). With the Hamamatsu HCImage software ( https://dcam-api.com/hamamatsu-software/ ) you should see both cameras and be able to take images from both cameras. If you switch to TDI mode you need to select “internal trigger” (on the HiSeq the FPGA generates the trigger). Remember you will only see some lines as this is a line camera - you should see changes in brightness if you cover the slit . I tested this and it worked for me. And then you can start playing with drivers.
PS: ChaosLooper is also on it’s way.
