Most of the discussion on this that other people have brought up, is
why I liked Brad Parkers "udisk" approach so much. His design goals
were:
Create a low cost unibus adapter card which can emulate a small number
of popular controllers (RL11, UDA50, etc) and use an IDE or CF disk as
the actual media.
Make it easy for others to write personality modules for different
controllers.
Should allow use of a IDE/CF disk to boot a PDP-11 (or vax).
Specifically, I was enamored of the approach that allowed a user to
write their own personality module to change it from acting like a
SCSI controller vs. SDI vs. etc.... all via software. This would seem
to me to be the most functional approach for the most people.
I'll pony up a bounty of $300 to get someone to take those design
goals through to a kit form. Anyone want to add to the bounty? Or take
up the gauntlet? :)
