So from the computerГўв‚¬в„ўs point of view, the type of drive would magically change when I flipped the switch, causing badness. I had almost given up on the adapter, when I realized the problem was that IГўв‚¬в„ўd combined a real 400K drive with a Floppy Emu that acted like an 800K drive. But there were some weird problems too, like disks sometimes becoming unreadable or failing to eject. It mostly worked, and I could use the switch, and the computer would only see the drive that was enabled with the switch. Not wanting to risk damaging the Lisa if the adapter was flawed, I tested the adapter on a Mac SE, with one 400K drive and one Floppy Emu. ThatГўв‚¬в„ўs similar to how the external and internal floppy drives are connected on a Mac. The read lines from the floppy drives are connected together, but that should be OK since only one drive will be enabled at a time.

This adapter connects power and the computerГўв‚¬в„ўs floppy outputs to both drives, with a manual switch to control whether the computerГўв‚¬в„ўs enable output is connected to drive 1 or drive 2. So instead of installing BLU to the hard drive, I switched to my backup plan and built a two port floppy drive adapter with an external enable switch.

But wait a second вЂ“ the M key on the LisaвЂ™s keyboard is broken! Argh! No HD install for me. After reading the BLU documentation, I learned that the HD install option is in the вЂњmiscellaneousвЂќ sub-menu, accessed by pressing M from the main menu. ThatвЂ™s not great, but because it would enable me to run BLU from the HD while testing a Floppy Emu on the floppy port, I decided it was the best option available.

IвЂ™d been resisting that solution, since a BLU hard drive install wipes out anything else on the HD, which makes it impossible for me to run further Macworks tests.

I finally decided to install BLU to the LisaвЂ™s hard drive. The Lisa only has one floppy port, and I donвЂ™t want to hot-swap the drives. As I mentioned previously, the tricky part with BLU is that it needs to be loaded from a real floppy disk, but I also need to connect the Floppy Emu in order to run tests on it. The BLU Basic Lisa Utility seems to be the best tool available for this.Д«LU isnвЂ™t an application, but is a вЂњbare metalвЂќ program that loads instead of the operating system. ThereвЂ™s been no progress on the Lisa disk emulation itself since my last update, but IвЂ™ve spent some time getting the Lisa into a state where I can collect better floppy diagnostic information. I always operate my computer on a mahogany desk, while wearing a suit and tie.
