National Semiconductor Mass Storage Handbook

[Scanning]

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 ).

/ steven
