Hi,
i got a request from someone who wants to emulate a DB8490 in a FPGA ...
... this will be used for a homebrew NS3532 system, that will somehow emulate a pc532 (to
get
NetBSD up and running ...).
Unfortunately, i don't have my National data book currently at hand (it's
somewhere hidden under
some piles :)), on bitsavers, i didn't find it too and google wasn't me friend
too ...
Does anyone have an online copy available ?
I am pretty sure the National Semiconductor disk controller databook is
on bitsavers (Al very kindly scanned it when I was asking about data
separator ICs to help with sorting out an HP7959B). I remember the links
to it wrre pretty obvious (something like national/databooks), but I
can't rememebr exactly.
That databook should contain the 8490 too.
