I was just taking apart my SE/30 because my repaired board will be here today.

Problem is, I found a very small jumper laying inside of the computer... is this the HD's jumper, or are there any jumpers on the analog board that could have came off? Just wanting to know before I power it up!

EDIT - Nope, pretty sure it belongs to the HD....the HD has no jumpers on it, but I looked up the drive's jumper settings (Fireball 1280S). Not sure why the jumper was on the drive....I know I don't want to enable termination and with all jumpers off, it's set at SCSI ID 0.

#2 Wed, 21 Mar 2012 - 14:13 68kMLA

It was probably "half on" the HD (i.e., stored for potential future use).

Changing gears here.... I can't get it to accept a floppy. It will take it, read and give a happy mac, then spit it out with an X on the floppy. These are System 7.5 disks.

#4 Wed, 21 Mar 2012 - 15:00 68kMLA

Are you sure the disk is good? See if it will boot another mac. If not, check your connections and reset the PRAM. If that doesn't work, try another cable. (Learned that lesson the hard way one time

)

Disks are good... used them to install 7.5 on my LC II. Connections are good.

Maybe the drive needs greased? If any Mac floppy drive will work in it.. I have tons of them.

Drive in the SE/30 is a Sony MP-F75W-01G, and the extra drive I have is a Sony MP-F75W-11G. Interchangeable? I'm assuming they are.

EDIT - I'm dumb. Google is my friend. http://lowendmac.com/macdan/md07/0926.html

#7 Wed, 21 Mar 2012 - 15:38 68kMLA

YES!

It was the drive!

#8 Wed, 21 Mar 2012 - 15:44 68kMLA

Hmm.... HD SC isn't picking up the hard drive that's installed. Is the internal drive supposed to be terminated with the jumper?

#9 Wed, 21 Mar 2012 - 16:37 68kMLA

Parity enabled or disabled?

#10 Wed, 21 Mar 2012 - 17:57 68kMLA

I'm learning! :lol:

I found the problem. Apple's HD SC only works with Apple branded drives. All other drives come up as "not found" or "not supported".

All the other drives I have are Quantum store bought drives or Quantum/LaCie Silverlining drives.

#11 Thu, 22 Mar 2012 - 00:45 68kMLA

Well its good the board arrived in one peice. And working.

Oh and when I did the videos, my drive started doing a similar thing. So i need to clean and demagnetize the heads without breaking the tension or alignment.

#12 Thu, 22 Mar 2012 - 03:27 68kMLA

Ok, one more dumb and probably easy question... Why can't I get my external CD drive to work? I installed Apple CD 5.4 on system 7.5, and it still won't recognize the drive.

My 5500 with 9.1 recognizes the drive....but here's the thing... the SE/30 WILL recognize a hard drive connected via the CD drive enclosure when I take it apart and jerry rig it. Am I still using the wrong CD extension version? It's a ClubMac drive with a 8x NEC CD Drive.

#13 Thu, 22 Mar 2012 - 03:28 68kMLA

Because its an NEC drive. You need a 3rd party extension to make it work. I used to have an NEC drive and had the very same exact problem.

its not Apple ROMed, so you need an extension such as CD-Sunrise on an older system.

#14 Thu, 22 Mar 2012 - 03:36 68kMLA

Ahh... like I said... something obviously easy.

I'll give that a try... if I can't find CD Sunrise, I'll pop an Apple ROMed drive in the enclosure.

#15 Thu, 22 Mar 2012 - 03:58 68kMLA

Found CD-Sunrise, and it works! I now have a functional CD drive.

#16 Thu, 22 Mar 2012 - 11:01 68kMLA

Ok... I'm just going to make this my "Dumb questions for my SE/30" Thread.

The memory I got doesn't work. It's apparently not compatible. When I put it in, I got the death chimes as soon as I flipped the switch. Here's the memory I bought - http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=350478816084

Did I buy the wrong memory? Of course I did..... right?

It DOES work in my LC II though.

#17 Fri, 23 Mar 2012 - 02:13 68kMLA

thats a good question. I dont know.

#18 Fri, 23 Mar 2012 - 07:22 68kMLA

I believe your issue can be solved by checking out this article on upgrading RAM in your SE/30. I've never personally upgraded RAM in an SE/30. The specs say groups of four, and the LEM article says to populate all slots with identical SIMMs. Were there eight identical SIMMs to begin with?

Hope this helps!

#19 Fri, 23 Mar 2012 - 22:33 68kMLA

As Theianman85 mentioned, did you buy four of the SIMMs and install them as a group? The SE/30 requires memory in groups of four identical SIMMs in each of the two banks. If you only bought and installed a pair, it won't work.

#20 Sat, 24 Mar 2012 - 00:51 68kMLA

There's some good clarification. The LEM article threw me off a bit speaking of using all eight banks when Apple and Mactracker said groups of four.

So more RAM seems to be the answer!

#21 Sat, 24 Mar 2012 - 04:11 68kMLA

More RAM is ALWAYS the answer! :lol:

#22 Sat, 24 Mar 2012 - 18:28 68kMLA

Yup, they were installed as 4 SIMMs. I found out I got the wrong memory, and sent it back this morning. Just to confirm, is this the memory I need?

http://www.ebay.com/itm/4x-4MB-16MB-30pin-SIMMs-RAM-APPLE-MEMORY-non-parity-4x8-/150640594875?pt=Printer_Accessories&hash=item2312e10fbb#ht_500wt_922

If so, I'll buy that one.

#23 Mon, 26 Mar 2012 - 07:51 68kMLA

Strange... the SE/30 doesn't need parity modules, but they should work fine too -- the extra chip is simply ingnored (not connected to the datapath)

The last link seems to be compatible memory, but the previous one should have worked too -- they did on the LC II, didn't they?

#24 Mon, 26 Mar 2012 - 15:33 68kMLA

2 of them worked fine in the LCII, the other 2 gave death chimes. I bought them from a reputable place and they were sold as fully tested and working. I put all four in a 486 PC I have, and it recognized them all as 16MB, and the computer ran fine.

I seem to have the weirdest situations.

#25 Tue, 27 Mar 2012 - 02:47 68kMLA

i know the logic board isnt at fault, i tossed everything I had in it and it worked fine.

#26 Wed, 28 Mar 2012 - 17:38 68kMLA

It was definitely the memory. The memory gave death chimes in the LC II as well.

On another hand.... what's the best Stuffit version for the SE/30 running 7.5.5?

I ended up ordering some memory from eBay that is 100% tested as good and working in Macs. The seller claims it was tested in an SE/30 as working.

Posting this post from a 7600/120 with a 333MHz G3 card and 384 megs of RAM.

#27 Wed, 28 Mar 2012 - 22:48 68kMLA

StuffIt 5.5 runs fine on 7.5.5, and is compatible with most (if not all) .sit files, unlike earlier versions. I think you can even use it on 7.1 if you have the Thread Manager extension installed.

#28 Fri, 30 Mar 2012 - 16:27 68kMLA

All is well. Got the correct memory in the mail this morning. I now have 20 megs of RAM. (4 x 4MB and 4 x 1MB)

7.5.5 flies on it with 20 megs... it crawled with 5.

#29 Fri, 30 Mar 2012 - 20:56 68kMLA

Ahh.... much better.

It looks like you still need Mode32 and 32-bit addressing turned on.

#31 Fri, 30 Mar 2012 - 21:07 68kMLA

Yeah, I haven't downloaded it yet. I plan to tonight.
