Working for an Amiga Dealer, we came across 256x4 ZIP chips with a pin missing many times, in fact my 2630 has them in it now. There should be absolutely no problem with these, as the 2630 has an unused pin hole anyway. *DON'T* solder the chips right into the 2630 unless you are sure the RAM chips are all in good working order. If you get a bad chip, you could end up damaging the board trying to pull it, and all the others you'll have to test, out of the board. Find some ZIP sockets to solder in, you won't regret it! They're somewhat hard to find sometimes, but they are available, and only cost $1-$2 each. * Scott Busse email: O O O_ _ ___ ..... * ||| /|\ /\ O/\_ / O )=| * a763@mindlink.UUCP l | | |\ / \ /\ _\ * May the frames be with you... \

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 gilgalad@caen.engin.umich.edu gilgalad@dip.eecs.umich.edu gilgalad@goliath.eecs.umich.edu Ralph_Seguin@ub.cc.umich.edu gilgalad@sparky.eecs.umich.edu USER6TUN@UMICHUB.BITNET Ralph Seguin | In order to get infinitely many monkeys to type 11010 Lighthouse Dr. #234 | something that actually makes sense, you need to Belleville, MI 48111 | have infinitely many monkey editors as well.

Now I have BTW, I requested our purchasing dept to try to locate some NEC 424256-10's for this old 2500/20. He finally found some at the 7th or 8th vendor who normally keeps them as a stock item. Several vendors stated that in the last month or so there has been "a kind of a run on these chips, but a bit strange since they are only being ordered 16 at a time". :^) ==================================================================== Kent Polk - Southwest Research Institute - kent@swrinde.nde.swri.edu Motto : "Anything worth doing is worth overdoing" ====================================================================
