There may have been Apple machines with ST-506s but unless my memory 
is much worse than I hope, there was never a Macintosh with an 
ST-506.   Unless you're thinking of the "Macintosh Hard Disk 20"? 
But looking through old emails, that has a Rodime Model 552 drive 
inside with a mysterious 26 pin interface, not an ST-506.

Outbound was a company.   So they were producing non-Apple 
Macintoshes by scavenging Apple ROMs from Apple machines.

The model number in this case is the Laptop Model 125.   A very cool 
machine with four SIMM sockets devoted to a "silicon disk"--that is a 
dedicated RAM Disk.   You could install up to 16MB in there--at 
least.  I have not tried 16 MB SIMMs yet.

The keyboard was detachable and had an IR interface.  It also had a 
trackbar ("isopoint") at the bottom of the keyboard.   A ?-bus (not 
PS2, not ADB that other one used on PCs (required an ISA card) with a 
round connector) mouse could be plugged into the keyboard if one 
preferred a mouse.   Additionally, using the optional SCSI adapter, 
the Laptop could be "docked" as an accessible SCSI device on any 
Macintosh with a SCSI interface.

The Laptop 125 was around as early as February 1990.    I'm not 
certain exactly when it was first released.  It pred-dates the 
Powerbooks.   So, e.g. the cool SCSI docking feature was available on 
an Outbound, long before it was a feature on the PowerBooks.
