@cypnk @320x200 Is the fact that car-radio-sized transceivers fit into 5¼” drive bays a happy coincidence, or were PC component standards influenced by automotive standards beyond the use of Molex connectors?

@acb @320x200 I think it's just coincidence. Most of those radios fit ISO 7736:

Which is really intended for vehicle radios (and a lot of mobile CBs tended to fit this or under single DIN)

But drive bays are usually 146mm wide

transceivers looks really similar to the FM radio that installed on cars XD
