So true!  I did end up adding a Windows build. The terminal I/O isn't 
nearly as fast as the Linux/OSX variants, but I didn't compromise 
performance on the Unix side of things.

I also just added Western Digital WD1002·05 hard disk controller 
emulation to get HD support (that was a bear!).  You can now run a 
Kaypro10 with ./izkaypro --model=kaypro10 .  Drives A and B are 5MB hard 
disks, and drive C is the floppy per the original Kaypro10.  It's 
running the 2.2u1 BIOS.

Then I went a little bit crazy and decided to make the penultimate 
Kaypro!  The new machine is a Kaypro 4-84 running the TurboROM 3.4 BIOS 
plus HD support -and you get the RTC and serial port to boot!  Just run 
./izkaypro --model=turbo_rom_hd .

With the TurboROM BIOS, drives A and B are 5MB HD partitions and you get 
two floppy drives, drives C and D, just like you would have if you 
attached an HD to your original 4-84.

This should keep the Kaypro people quite happy, all 50 of us.
