The Outbound Laptop Model 125 (ca. 1989 Mac laptop clone) uses a Citizen brand PC type laptop floppy drive. It reads and writes 800K Mac floppies as well as 1.4 MB floppies on both platforms. However, it has a controller card on the end of the floppy drive. The main components of the floppy controller card are an 85C30, WD37C65, WD92C32 (confused as to why this is there, since the 37C65 has a data separater built in), an LS624 voltage controlled oscillator, a Xicor X9103 digital potentiometer, a 27C256, and a GAL16V8. There's a little bit of other standard 74 series logic on board as well. My main obstacles to cloning the thing is an affordable source of the WD92C32 and the time and method to extract the logic of the GAL. I find it interesting that back in 1989 someone had already found a way to make a PC floppy work as a Mac floppy, though with a double handful of chips. I'm not quite sure what kind of interface the Outbound uses to the floppy drive, though. Obviously, there's no SWIM chip in the Outbound. So did the original designer (Doug Swartz?) cobble up a SWIM from 74 series logic or does the controller on the floppy negate the need for the SWIM? The thing that particularly arouses my curiosity is that the Laptop 125 has no SCSI port, nor external floppy port. But it has a Hirose brand DX10-28 connector (looks a lot like a mini-centronics). That connector can interface to an external floppy or external SCSI controller. The interface point for the external floppy is the 85C30. The interface point for the SCSI controller is a 53C80. So I wonder what the Outbound is using for signals on that 28 pin connector that will work for both of those interfaces and make some kind of sense to the Mac guts at the other end. Jeff Walther
