Restoring a ThinkPad 365ed

#1 Post by jhend1000 » Mon Jul 23, 2018 11:33 am

Hi all, I recently picked up an old IBM ThinkPad 365ed off of eBay as a project to revive and restore. This laptop currently does nothing but come up with a black screen, a power light, and some other light I don't remember the purpose of at the moment. Upon opening it up, I have found that there is no RAM present in the laptop. What type of RAM does the 365ed use? I've seen a few sources that say it's one of those IC DRAM Memory Cards, and others say that it's just standard SO-DIMM. Looking at the motherboard, I don't see anywhere to put any SO-DIMM type RAM. Is there some sort of optional daughterboard that can be installed on the motherboard to allow the use of SO-DIMM, or does this ThinkPad use the IC DRAM Memory Cards?

Thanks

Welcome to the Forum.

Hunt Google for tpvol3.pdf, which is the 365 manual.
Go to the Drivers link at the top of this page for... drivers.

For SO-DIMM, see page 63 of this. By the way this comes from the "HMM" section of this very page, you have the link two inches above your post. Also, some photos here.

Thanks for the input so far, it's been helpful. That PDF Manual would imply that it uses SO-DIMM type RAM. I'm not seeing any SO-DIMM slots on the motherboard though... Is there a separate memory board that can be removed from the motherboard?

Read that HMM and see in the Parts listing.

Looks like the FRU is 88G1262. I've looked that number up on google before and the part I see doesn't look quite the same as what's in the HMM. If that's what it is though, I'll go ahead and order it. This is what I'm referring to: https://www.servers4less.com/memory/laptop/ibm-88g1262

Thanks

Don't!
That's only a RAM-module! (And very expensive!)
You need a module-holder board 75H7624 first, as shown on HMM page 63.

Ah ok, now I finally get what it is I need to find! I need that board with the insulator bracket, along with an actual stick of RAM. Is that correct?

So I was unable to find this memory board module that I need to install RAM in. It appears that no one on the internet has one of these boards available. Looking at my 365ed when I got home from work, I see where this board is supposed to be installed at.

Does anyone happen to know where to source these? If it comes down to it, I might just build one from scratch, (I am getting my degree in electrical engineering so I know how this stuff works).

You may ask Impact Computers. I got from them some parts for my 390X, which were not available anywhere else.
IBM 390X(W95/W98SE) | T23(W2K/XP) | R51(WXP)
Lenovo R61(WXP/Vista) | T540p(W7/W8.1/W10)

Thanks for the reference! I'll give them a try. It looks like they don't have it in stock but might can get it for me in a few days. I suppose this is my best option for the time. I'll be sure to keep everyone posted on the progress of this ThinkPad.

Thanks

Would this not be the part I need? https://www.impactcomputers.com/ibm-thi ... pidx=24329

Is the insulated bracket board not just the bracket that can hold the optional SODIMM RAM stick in place?

I have parts from a broken 365XD including a RAM module, if you want to pick up anything. Mine doesn't work.

Thanks for the offer! I did end up ordering the parts from Impact Computers. If they send me something that doesn't work for my 365ED, I might take you up on that. Do you have any pictures of the RAM module?

Thanks

The 365ed now POSTS and comes up to the BIOS! If you ever are looking for obscure or hard-to-find parts, I would highly recommend checking out Impact Computers. They had that RAM board that I couldn't find anywhere else. Now the question is, how does one get these to boot from the CD-ROM drive? I am surprised that this actually has a Phoenix BIOS on it.

Looks like the CD-ROM drive isn't bootable. I've got an external floppy drive for it on the way. It's the specific one that apparently came with the laptop.

OP: Where did you source the floppy drive? I recently acquired a 365CD and need the same drive for mine.
