[comp.sys.amiga.tech] ZIP chips for 2630

gilgalad@dip.eecs.umich.edu (Ralph Seguin) (05/02/90)

Howdy.  Well, I just went out and purchased some ZIP rams.  Now I have
run into a problem.  The ZIPs that I got have a pin missing in every chip
I don't mean missing as in broken, it just seems as though they are different
somehow than the ones that are already on my 2630.  Do you know whether or
not the NEC ZIPs on the 2630 have a dummy pin (or a ground), or do you know
what the deal is with my ZIPs?  Also, would it be alright to solder ZIP
sockets?  If so, where can I get good (hopefully cheap), ZIP sockets?

I saw a 3000 today.  Was sorely tempted to steal it. 
Honesty does have its downside 8-)  I read a few of the things you were
discussing about it.  There was much discussion on the 040.  Does this mean
that we're going to have YAKA (Yet Another Killer Amiga) on the way? 8-)
 
			Thanks, Ralph Seguin

The ZIP's I installed in my Amiga 3000 were also missing a pin in the
middle. They worked fine - even plugged one in backwards and powered
up - no problem! (phewww) I don't have the pinouts, but I suspect the
missing pin is designed to break the power connection to the chip when
plugged in the wrong way. Are you sure you original ZIPs aren't missing
a pin? Pull one out carefully and find out.
