The problem with the silicon film product is that it had no interface to most cameras - nearly all cameras. A sensor is not like film. Film is 'always' ready to capture electrons, which is why you have to keep it dark before and after exposure. A silicon sensor is electronic and requires electronics to 'turn it on' and to 'move the pixels' off of the sensor and into storage. Just inserting the silicon film module into a film camera simply won't work. There is nothing to tell the sensor electronics when to 'turn on' and start capturing electrons. Likewise there is nothing to tell it to stop and 'read-out' the pixels. A digital camera's shutter is tightly coupled with the sensor electronics. There is a hellova lot of firmware executed when the shutter release is pressed. The last part is triggering the sensor 'ON' just before the shutter starts to open, and triggers it off just as the shutter closes so that the pixels can be read out of the sensor as quickly as possible. There are no controls like this when sticking a silicon film module into a film camera. The company managed to 'Rube Goldberg' up an interface to a couple of film cameras, but it was obvious that the thing would have no future.
