Want too upgrade the memory in my maciintosh se. 1mb does nothing these days. Even 4 is not much but at least I can boot system 7 and do more things. Can anyone verify this would work. Can't find 1mb simms anywhere else.

I think they should work, as long as they're in pairs (SIMMs always had that problem).

Yep, looks good. The guy doesn't specify what speed of RAM he'll send you, but that doesn't matter; according to Apple (http://support.apple.com/kb/TA34950?viewlocale=en_US), anything 150ns or faster will work in your system.

But 60 is not faster right. Or is it lower number faster and higher number slower.

Your SE should run fine with 60ns SIMMs, just so long as the speed value is 150 or lower.

OK also how to add the memory. I wish there was a video or something.

Also anyone know why se/30 has 8 slots and fd/hd has only 4 since it is newer. Or is the net wrong. Cuz if so then fd/hd should have 8 also since its newer. Why go back to 4.

Just a guess but they probably upgraded the maximum SIMM density but with that they would hit the chipset limitation of 4 slots. For example, the old max density could be 8x1mb whereas it could be 4x2mb on a new system. As for SIMMs, they are extremely easy to install. Similar to SODIMMs in a fashion.

Yes but I'd really like to see photos or a video. Don't want to fry my se. And SE/30 is 128mb ram max and FD/HD is only 4mb so its not an upgrade.

Wow just found good prices. I hope this is legit.

1 dollar and 28 cents is very good. But is SE/30 ram the same as FD/HD?? Or did FD/HD use different simms?

SIMMs are SIMMs are SIMMs are SIMMs, unless you've got an IBM PS/2. There is no such thing as SE/30 specific RAM or SE FD/HD specific RAM.

But there is some difference. Some have 2 chips and some 3. And Some fill up the whole stick. And I can't find the link. But somebody was saying (I think it was apples website) se/30 can't use 2 chip simms. So I'm confused. But I guess I I'll try the other ram and see. Now if I only had a vide or something showing how to add the ram and what have you.

That difference in the chip count has to do with the density of the chips.
If a 512 KB SIMM RAM stick has 3 chips, then each chip is 170,67 KB.
If a 512 KB SIMM RAM stick has 2 chips, then each chip is 256 KB.
RAM compatibility should not be influenced by chip density.

If in doubt whether a piece of memory will work, just go ahead and give it a try! As long as the # of pins match and the piece of memory physically fits in the slot, you really can't fry anything out (am I right, guys? Or can you guys think of a counter-example to this?) The worst thing that will happen is you will get the Apple "chime of death" which means that 1) your memory is the wrong speed 2) it's not the right architecture (ECC, non-ECC, registered, buffered, whatever, etc... but that isn't even an issue for these old SIMMs) or 3) some SIMM pairs aren't matched correctly.

If you get the "chime of death", simply shuffle the SIMMs around in the slots or try different ones until something works. You'll always learn best by doing rather than by reading literature/websites.

Yes thanks. But I also have no idea how to discharge a crt. I also don't know what is safe to touch and not. Don't want to electricute my self. So that's why I thought a video might help.

If at all posible do not mess with it if you have to deal the crt. Because if you end up getting shock you may not live to tell about it. And if you do you more than likely you will damage the hardware from ESD. If I was you I would take it to somebody who have expieriance with TV's or CRT's.

The SE was released in March 1987 and was one of the last 68000 Macs. All versions of the SE are based on the same hardware with only slight revisions being made over it's lifetime. The FD/HD was just that, a revision on a 1987 piece of hardware.

The SE/30 was released in January 1989 and was basically a Macintosh IIx that had been chopped down to fit the original SE form factor. Outside of the display and case, the SE and SE/30 are completely different beasts. Any revisions to the SE didn't incorporate the new features on the SE/30's logic board because that would have forced Apple to develop what would effectively be a completely new computer. Early 68030 Macs were the first to have 8 SIMM slots, there was never a 68000 Mac with 8 SIMM slots. Though I can't say with absolute certainly, I'd suspect that this was a limitation of the SE's ROM and/or memory controller, as even the highest end PDS slot upgrades for the original SE didn't allow the use of more RAM slots (though some did allow for a 4x4mb configuration.)

Eh, in theory this is true, but there are a ton of vintage Macs that range from moderately picky to extremely finicky about what RAM they will accept. Low density SIMMs/DIMMs are often problematic for the older Macs. (Also, not all the classic Macs used 30-pin SIMMs. Some used 64-pin or 72-pin SIMMs.)

For the SE specifically, any 30-pin SIMM that is populated with 128kb or lower memory chips should do the trick. The SIMMs pictured in the link from the first post are 8x128k=1mb SIMMs and have a good shot at working.

You'll be hard pressed to find a video of an SE tear down, but Apple's SE service manual is still available online. If you search for "MacSEservice.pdf" (no quotes) on Google you should be able to find websites from which it may be sourced.

As for discharging a CRT on a compact Mac, read sections 3 and 4 here (I know the link is for an SE/30, but the displays are identical). If after reading the SE service manual and the previous link you don't feel comfortable discharging a CRT, then don't do it. An upgraded Mac SE is not worth risking serious injury.

Additional (miscellaneous) notes:

• All SIMM slots must be filled, thus only the following memory configurations are allowed: 4x256k (1mb), 2x256k + 2x1mb (2.5mb), or 4x1mb (4mb).
• The SE will run pretty much any MacOS you throw at it up to 7.5.5 (though you'll want 4mb of RAM to go above 6.0.8.) I've personally run OSs as far back as 1.1 on an SE.
• If you can find any sort of upgrade for the SE PDS slot it's almost certainly worth picking up as these are pretty rare. (note: the SE PDS slot is not compatible with hardware intended for the SE/30 PDS slot.)

Also, this is what the SE looks like on the inside:

(You'll have to remove most of what you see in this picture to do the RAM upgrade.)

Orjust saw some good deals on ebay. Would any of these work.

http://www.ebay.com/itm/4-Vintage-1MB-3 ... 010wt_1270

http://www.ebay.com/itm/4-Vintage-OKI-1 ... 010wt_1270

I would expect these to be the better bet.

OK I ordered those as you suggested. Plus a lot of other sites say 9 chip simms are good for old macs. So cross fingers. Will let you know when it arrives.

Just found this. It is SE/30 not FDHD. But can anyone confirm this is the same for my fdhd. At least opening wise and adding ram. I know I have only four slots and not 8. But at least opening wise and removing the board to add ram. At least up to that part. Everything it says to disconnect and do. Or is 30 different than FDHD.

Finally figured out how to crack the case open. And ram arrived today. So nobody can verify the above link is correct of the same as my FD/HD even though it for SE/30??

It should be almost the same. For opening and adding RAM, it should be almost identical to the guide you found.
