Tony,
I have a datasheet for the DP8464 ( supposed to be similar to the 8468 ) and
a bunch of Application Notes for using that family of parts ( i.e. AN774,
AN414, etc..). It would be helpful to know if it is a pulse detector, data
separator or whatever function you think it might serve.
I also have a datasheet for the AMD8751 / 8753 which are the EPROM versions
of the factory mask ROM 8051 and 8053. The 8753 has 8 K of EPROM and same
functionality as the 8051 / 8751 ( 4 K ROM / EPROM ).

Subject: National Semiconductor Mass Storage Handbook
Does anyone have a National Semiconductor Mass Storage
Handbook
(databook) from around 1989? I am looking for datasheets (or at least
pinouts) for :
DP8468
DP8465
DP8455
DP8462
DP8463
Datasheetarchive and Digchip don't have anything, and a google search is
not helpful.
In case you're curious, I am trying to identify a house-coded part with a
National Logo that I suspect is one of these devies. 24 pin shrinkdip if
it helps..
On another subject, has anyone heard of an AMD 8053? 40 pin DIL, I
suspect it's a derivative of the 8051 microcontorller. No I don't mean
8035...
