#184414 - 8255
Responding to: Richard Erlacher's previous message
Richard Erlacher said:
Lots of people have, for example, expressed their hatred for the 8255 as a general-purpose parallel interface. Well, if it will do the job, and if it is already on hand, why not?


Except it's not on hand.

Using the handy-dandy website FindChips, it turns out that none of the mainline stockists have any 8255s in inventory or even in their database. Those distributors that DO have the part are those that specialize in obsolete parts.

Just sayin'.
