I do have a question. The board has a delay line to
create the early and late signals for writing the bits.
There are no numbers on it. Does anyone know the
values used for early and late on double density 8 inch
and on double density 5.25?
Hi
I was just looking at the specs for the I82077. They list
the compoensation values, as recommended, of 125ns
for both 500 kbs and 250 kbs. I would guess that means
I could use the same delay line for both.
I don't expect I'll need it anyway since I'm primarily
reading disk. It would be nice to both read and write
once I've completed the project though.
