Drives are long gone but I actually ran into a winchester controller card
the other day. Some of the younger guys couldn't id it. Also found a
Mono/Printer card that had ~40 socketed 16-22pin IC's it dated 1985

Which part - S7/S9 or caching?  S7/S9 is part of the record format
but I've never seen a "standard" doc on although I know they exist.

The "caching" is more targeted at the agent. Since it will require
"download pgm" -> "Agent" -> "Device" I'd like to see the agent
build a complete valid image (disk, shared memory that can be
released) and validated it so it can be blasted to the device. This
image is, of course, device dependant - for the Ocelot it would be
regenerating the binary image - for my PRI cards I would just store
the S records and make sure they are all in tact and match the S9...

I know very few high-end developer with a lot of experience that haven't
had to deal with S records and some of the other "lower level" stuff
before so I'm not in the least suprised.
