When installing 4MB simms in the NeXT station, if I'm only installing four does it matter where thay go and if so should I put them in the bank next to the hard drive or the one next to the power supply. Aloso, do I need anykind of special tool to do it? I think all I need to open the slab is a phillips head screwdriver. Thanks in advance for all the help.

A Philips screwdriver pulls the cover of the station, but pulling out the old simms is quite an art: one should get a special tool for them, since you need to hook it into the two holes AND push on the snaps which hold the simms in place. The technician at the Campus Bookstore, and myself improvised a device, using a heavy paperclip and a tiny screwdriver (to push back the snaps), and we finally managed to do it by trial and error. I would advise GETTING THE RIGHT Simm-puller before attmepting to do this single-handedle ( or even at four hands ): is is too easy to damage the simms. Good luck!

After nearly killing my fingers (and some SIMMs) I discovered the NeXT tool works just dandy for getting out SIMMs. Just stick it in one of the holes, and torque the SIMM a little ways out, then do the same on the other side. The SIMM will now pull right out. Unfortunately NeXTstations don't come with NeXT tools, so this does you bean lot of good. DISCLAIMER: I'm sure the NeXT tool wasn't intended for this, and if you follow my advice you'll probably destroy your machine and your memory and your dog will leave you. -william shipley danger seeker

Actually I have them the other way around and it works fine too. I took out the first 4 SIMMs (the ones closed to the hard drive) and replaced them. Everything went fine. Taking out the old SIMMs without a special tool was a matter of thinking. With two flat screwdrivers (one small one and one medium sized) you come a long way. The main point is that it needs some force to get the SIMMs out of the slot (they are clipped in) but you do NOT want to apply force to the main board. Hence I stuck the little screwdriver in a hole and put the medium screwdriver on the size of the slot, below the small screwdriver. By rotating the medium screwdriver you exert a large enough force on the small screwdriver to have the SIMM come out on that side. Etc. I offer no guarantee that this will work with your computer. It just worked with mine (and my two screwdrivers). Jos Vermaseren PS. The above trick was invented by Archimedes trying to lift his CRAY with his NeXT workstation.
