Hi folks,

I don't know if it's a fact of certain interest...

I found a DEC M841 Omnibus printer interface with a Fairchild "F 7429DC" 
additionally stamped "DEC8881". As I think the DEC8881 is considered one 
of the harder to find chips, this could be interesting. I know that many 
of the DECxxx ICs are pin compatible to standard 74 TTL or Signetics 82 
TTL devices so this could be found out by reading the TI data book as 
well. But I've heard of signal quality, speed and other selection issues 
making those a DECxxx IC. Perhaps that's a legend? Or at least partially?

Best wishes,

Philipp :-)
