Would anyone on the list have the datasheet for the National Semiconductor
DigiTalker Chip Set? Nat Semi part number MM54104.
It was also sold by Jameco as part number DT1050 (I believe IIRC).
I have searched my stock and files, but can't find the datasheet. I found
the chipset, but have no data.
I have searched the web and can find the pinout and some rough spec's, but I
need a little more application data.
Yes, I know it is obsolete, but this is a one off (for right now anyway).
If I need further, I'll try a different chipset.
But this will prove (or disprove) the concept.
