I read Apple hinted that they intended to introduce an expansion card for adding an external 400K drive following the release of the Lisa 2, which only had one 400K drive. From what I can tell this never came to pass. I also cannot find any evidence that a third party offered an expansion card for this purpose either.
This seems odd considering that hard drives were so expensive and a basic Lisa 2 system with one 400K drive and 512K RAM would be no different than a 512K Mac, meaning an external disk drive was a necessity. I suppose upgrading to 1MB RAM would make a huge difference in making disk copies, or loading applications into a RAM disk, and would be a better investment than an external drive.
I was informed that the Lisa's 400K disk controller card supports 2 drives and a second drive could be hacked onto the card. Is anyone aware of this particular hack? Considering the Mac ROM supported two drives, MacWorks should support the hack.
Since the Lisa software required a hard drive, a second 400K disk was probably deemed unnecessary. Although, I can think of a number of times I have needed two floppy drives when I had a hard drive – especially in those days when many applications would not work properly from a hard drive and key disks were needed to authorize copies of an application.
