DIP-64 packet.

Ahh those days 
I also remember large pincount DIP with staggered pins, instead of 2 rows of pins in a normal DIP there were 4 rows. Funny to route...

Do you mean these Rockwell MCU's? They were pretty tough to get in/out of an IC socket.

Exactly! Although I think I remember I did designs with some devices with close to 100 pins or so. But they were funny

I came across (for the first time) a DIP-64 packet micro. It is HUGE! Was it common back then?

I've only seen them for Motorola 68000 processors and their ilk, but they certainly are monsters, huh?  Looks like an aircraft carrier with a bunch of escorts around it.



This is the processor board from an HP 3561A Dynamic Signal Analyzer built in the mid 80s.  The dual inline package was the prevalent package type when the chip came out, so I suppose it made sense at the time to simply scale it up.  I know some of the other packages were coming out in the mid-late 70s too, but don't believe that they had yet become particularly 'mainstream' yet.

Another 64 pin DIP from the 70's was the TRW 16x16 bit MAC chip that we used in digital modems and others in radar/sonar etc.  Still available on Ebay if you have $100 or so to spare!

The first 64 pin DIL package device I used was the TMS9900. The second was that TRW chip, although most of the ones we used were actually the AMD compatible chip which came a bit later. It was a mainstay for a lot of military FFT hardware for a while. At one point, we had large boards with one of those 64 pin chips on each. The boards had started out packed with AMD25S05 2x4 bit multiplier chips and carry adders. Just as we started to need a quantity of them, we were able to replace the original design with a board that had just one TRW chip, and a couple of glue chips. That's progress.

The early Macintosh and also I think the Atari ST used a huge 68000 DIP

Sega Genesis (Megadrive) too, also a Z80-CPU in DIP40.
