No I did not know of it being used anywhere else. It was that simplicity that made me extremely happy since it fit in a .3" dip pack instead of something relatively huge (.6") and also not needing separate I/O direction registers, etc. Imagine how happy I was when I went to the cabinet and pulled a part that did exactly what was needed (and pretty much nothing more). The fact it was our own chip also meant we didn't have to worry about availability as there was a huge LS shortage at the time and parts prices were consequently high. -----Original Message----- From: email@example.com [mailto:firstname.lastname@example.org] On Behalf Of Gerrit Heitsch Sent: Friday, March 23, 2012 1:14 PM To: email@example.com Subject: Re: mos 6529B datasheet ?

It's also me most minimal I/O-chip I know of, doesn't even have a reset signal.
