Sample block driver?

[John Bossert]

Sun's "Writing Device Drivers for the Sun Workstation" does a nice job of
describing character drivers and their components.  It also includes code
samples.  Does anyone have a sample *block* (disk) device driver they
could send me?  One oriented towards the VMEbus would be most helpful
since it would mesh with the samples (character) Sun gives.

Thanks in advance.
