PowerBook 550c

Took about 4-5 months, but finally found an original iTunes disc. Also, picked up a 240MHz PB 3400c for $62.65. More on that after the break ;)  

I was inspired after reading this blog post on one of the original iTunes CDs by Kevin Rye on his site, appletothecore.me, while I was hunting for one myself.

http://appletothecore.me/files/itunes204CDtake2.php

I had missed one that went up for sale on the Bay a few weeks before I started looking for a copy myself. Suffice to say, the wait was well worth it, and I was tickled to find this one last week! I'm sure more will pop up in the future, but this one is staying in my permanent collection. 

IMG_5471.JPG

Is there even a scratch?? Doesn't look like it (obligatory surface inspection, as per the blog post ;)

IMG_5499.JPG

The 550c doesn't seem to care for it much, though. :/  

IMG_5501.JPG

It appears to be version 1 as the Read Me update shows last updated 8 January 2001. Apple officially launched 1.0 on 9 January 2001. 

IMG_5481.JPG

Not to mention, it looks flipping smexy on the TAM. What

IMG_5483.JPG

While I was searching about for a power supply from a 3400c (since the stock power adapter for the PB G3 fits wayyyyyy too tightly on the power socket!!), I ran upon a PowerBook 3400c in the ended listings that had no buyer, complete with power adapter and CD drive.  

https://www.ebay.com/itm/Vintage-Macintosh-PowerBook-3400c-Series-Laptop/123128418617?hash=item1cab069139:g:-3IAAOSwodpa9wHy

IMG_5335.JPG

The thing that attracted me to it was the included 20x CD drive, which reminded me of the one that came with the PowerBook G3 "Kanga" I used to have. That, and the case plastics looked immaculate in the pictures. 

IMG_5333.JPG

So, what do I do? I sent the seller a message, asking if he planned on relisting his computer. The seller didn't respond until 3 days later, letting me know that he relisted it, and it was a Buy It Now auction for $49 plus $13.65 shipping. I bought it on the spot. After tearing it down, I found out there was corrosion on the board and on the connector of the LCD, so that explains the computer not starting up. A victim of pesky PRAM battery leakage. Sad. 

IMG_5340.JPG

When I got to the HDD, my heart kinda jumped with excitement. It was a 3GB drive, and if original to the computer, means I've just landed the 240MHz model! I knew this, because the 200MHz one I have had a 2GB drive, and looking it up I remember how unexcited I was about finding out the specs. Sure enough, when I got to the CPU, I knew exactly what I was looking at

IMG_5351.JPG

240MHz  :)

It looks like it has the original RAM, too, so I believe this computer is bone stock. Sadly, it displays nothing on the screen and there is no sound, even after I swap out the LCD and HDD...no power is getting to the display as it does not even light up. There is visible corrosion on the LCD flex at the connector. 

However, when HDD and LCD are swapped out, it "Bongs" to life when plugged in, and the HDD spins up as though it is loading the OS, so there is hope, yet! I'm going to try and see if I revive it back to life. Otherwise, on the bright side, it looks like it will make a good parts machine for the 200MHz model I have. And, I guess it will finally have a black keyboard again. :)

After some minor trace bridging on the 3rd 550c, I can finally set it aside as completely repaired. The only thing that was not an easy fix was getting the left side battery to be detected by the system. Under my microscope, you can see the pads are disconnected where I had scraped away the traces that were dissolved: 

IMG_5086.JPG

The battery leak corroded the traces connecting pads that linked the battery to the logic board. After determining the two connections that were affected by continuity, I cut some stranded wire to bridge those connections, and tinned the connecting ends so they could adhere to the exposed traces on the board. IMG_5096.JPG

Here, I tested for continuity at vias upstream from the bridging

IMG_5100.JPG

With new battery connectors soldered on, the battery is detected when inserted in either side. Everything else works as tested. This project is complete. 

IMG_5122.JPG

I made a repair video detailing each step, but I'm still working on wrapping it up. I'm still new to the whole iMovie software, and slowly learning how to use it, time permitting. 

For now, I uploaded this celebratory video I made a few weeks ago in honor of preserving four PowerBook 500 series computers (technically, I only worked on 3 of them, but will be working on the 4th when parts are available). I would say that's a solid conquest. :)

I like your idea of a collection — narrow and deep (with the exception of the TAM, of course).

You own the Powerbook 500 series and you probably spent less on it than many of us did on our sprawling collections (looking at myself here...).

Well done. This is how it can be done.

Haha, thank you! I appreciate that! It’s a bit more than I expected to spend ;)  I never intended to collect anything else after the TAM....that was an impulse buy, and I sold off the Kanga I had months before because I was afraid of the brittle plastics breaking in time. But I’ve always wanted the 550, and now I’m knee deep.  

I definitely intend to stick wiith the 500 series. But I see a lot of nice collections here, too. I’m afraid if I get started into anything else, I’m going to get sucked into a never ending vortex! Still nice to see what everyone here has, and especially nice to connect with you guys with similar collection interests and collections! I love sharing info

Received my first purchase from Mercari Japan. What appears to be a brand new Sonnet Crescendo/WS G4 500MHz/1MB upgrade card for the PB G3 Wallstreet, Japanese model (WSG4-500-1M-J). Great purchasing experience, fast turn around time! Hamada san took care of me all the way. 

I'd love to bust into it and upgrade my Wallstreet but if it's truly brand new and unflashed, I'm kinda scared to mess with it! :p  Software is in English. Anyone who has ever bought a Sonnet card brand new recognize if this is the original plastic on it? Appears to be unopened, but I can't be for certain. It was described in the Mercari listing as brand new: 

https://item.mercari.com/jp/m88560050736/

Item plus proxy commission: $235.93

Foreign transaction fee: $6.37

Shipping: $23.08

Foreign transaction fee: $0.62

Total: $266.00 USD

Damn, those are some cheap fees (granted I don't know what the proxy commission was). And shipping, too! How close to Japan are you? (I am used to ordering doujinshi from Japan to the US. How to go broke in one easy lessson.)

Haha, I never really calculate the fees in USD! Original price was 24000 yen. Hamada san charged me 25730 yen to make the purchase, and then 2517 yen to ship EMS (that was the fastest option he offered, or I would have used DHL). So, I think it was relatively cheap! And he was fast, too. Sent me shipping invoice Sunday morning, ordered Thursday or Friday night I believe. I didn't respond until Sunday night on shipping, and he gave me Tracking by Monday morning. 

The only issue is, the latency involved when ordering on Mercari through proxy. His site is vvJapan, I believe, and of two that I tried, he was the first one who got back to me, but it took like over an hour I think. Then another 20-30 mins to place order. I was kinda wondering what would happen if someone bought the card before me. The MO drive I ordered this morning was FAST though. Ordered around 10am this morning. He responded with a PayPal money request within minutes of me sending a purchase inquiry, and bought the drive just minutes after I submitted the payment. Guess it's a luck of the draw. 

I live in the US, so pretty far away from Japan!! Never heard of doujinshi before, but I'm open to trying anything out. I usually stick with whatever is working so far though! And I totally know what you mean! Calculating everything I've bought so far...looking at over a thousand dollars not including these recent purchases!

That is SUPER cheap in terms of fees. Your standard proxy services will often charge something like 50% over the original price of the item by the time all is said and done. You found a good guy!

Haha, doujinshi are fan-created manga (think fanfic, only graphic style). Totally different medium, but all my hobbies are geeky.

I have never ordered any computer stuff from Japan but you never know. I'll have to keep Mercari in mind. Keep sharing your Mercari purchases, I'll be interested to see them.

I guess he is a keeper then! Well, he was the first person to respond with a payment request, so I've stuck with him so far. I thought FromJapan proxy fees were fairly affordable, but I've never actually did the math. While everything is in yen, I'm used to thinking, "Oh, USD is pretty big right now, totally cheap! Very affordable! Much happiness! Wait...is that my bill??? Hmmm, looks like I'm eating dog food the rest of the month!" :)

Anyways, I'll definitely post anything new! And I am trying to give him more business, so if you need anything from Mercari, I highly recommend vvJapan! Just don't tell him he's cheap wink wink  ;)  

Missed this 2400c/240 earlier, like a couple weeks ago. Doesn't boot though, but sold for only 7999 yen ($72.66 USD). Allow me to kick myself:

Bought an Apple TechStep the other day for $199 shipped. Haven’t received, yet, but it only comes with two ROMs. Original eBay auction here: 

https://m.ebay.com/itm/Rare-vintage-Apple-TechStep-diagnostic-system-nice-shape-working-BIN-199/232801118597?hash=item3634072985:g:JHMAAOSwnOtbHVDT#vi__app-cvip-panel

28D4D091-1EC9-43C7-8D93-6FF9EF6780EB.jpeg

Anyone try one of these on a computer they didn’t have the ROM for? (Ie, what happens if I plug it into a 3400c that I’m trying to fix?). Also, where can I find more ROMs for this thing?

It seems that the 540c and the 550c M68k daughterboards have identical Apple Part number of 820-0559-A? If you still have the XC68040FE33M, I would like to buy it.
Appreciate your interest! I was about to sell one to a member previously, but the last 550c I imported turned out to have a 25MHz version from a 520c instead of the original 33MHz card...previous owner must have swapped it out (ironically, he was selling a 520c at the same time he had the 550c on auction. If I had only know...he probably left the card in that one, and I had no idea or I would have bought it, too! The dirtbag...).

The only one I have right now is being used in one of my PBs, which I need to use the other card expansion  :/

The TechStep arrived on the same day as a PB Kanga I ordered last week! Yeah yeah, so I've mentioned that I sold my first Kanga last year and wanted to get out of this collecting business (before joining this awesome community). Yet here I am, now with another one. Meh. 

Original listing of Kanga: 

https://www.ebay.com/itm/Macintosh-G3-Powerbook-Kanga-WORKING-Laptop-Mac-Apple-Power-PC-Vintage/223014088864?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649

Original listing of TechStep: 

https://www.ebay.com/itm/Rare-vintage-Apple-TechStep-diagnostic-system-nice-shape-working-BIN-199/232801118597?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649

Suffice to say, I wasn't sure which one I'd spend time with first. Interestingly... the seller shipped the Kanga in a Dell box. How fitting :)

IMG_5842.JPG

First thing I did: opened up the keyboard and removed the PRAM battery, which surprisingly, did not appear to show any signs of leakage! (hooray). Next thing, replaced the original 5GB HDD with a 30GB non-Apple IDE drive (would have been solid state, but my CF adapter has the old screw-hole arrangement). 

IMG_5844.JPG

I'll admit, I might have spent a bit much on the Kanga. The max RAM module (128MB) was what sold me on the deal though. And after the UK listing ended, I kinda feared that someone might snap this one up before I could. 

IMG_5827.jpg

Exhibit No. 2. TechStep....it looks cool. And old. 

IMG_5856.JPG

Wires feel old. There was a 9v battery installed, showing very minor signs of leakage. I pulled that sucker out as fast as I could (without damaging anything, of course). 

IMG_5849.JPG

I have nothing to work on it with right now. Thought about hooking it up to one of my computers to see what happens, as I'm curious to see if it would be compatible with some of the systems I'm working on. 

Anyone not familiar with this, the ROMs plug into the unit from the side. There are additional ROMs that I've read about for this machine. 

IMG_5853.JPG

And the checklist. I don't think I have the SCSI cable. Or the Mini DIN-8 cables (x2). I'm not sure what one of the cables is though, so maybe? 

IMG_5850.JPG

Wonder what happens if I mail the registration card in ;)  heh heh

It has been a little while since I've posted any new finds. I waited until I received my 3rd Color Classic II today...did not expect to be acquiring this many. The first one, not pictured, came with broken front bezel on three places, and half the screen is green-tinted .... probably degaussing issue? That became my parts machine when the second CCII stopped working: the analog board became defective after reassembling the unit, not realizing the grounding harness was not properly installed, and the motherboard would power the computer on but not boot after I cleaned around the capacitors that seemed to have leaked. 

IMG_6990.JPG

The first two I bought through Mercari: 

#1: 4500 yen, unit only

https://item.mercari.com/jp/m51404873341/

Price conversion, adjusted with proxy commission: $51.17

Shipping/handling: $178.29

Total value: $229.46

#2: 10,000 yen, unit plus keyboard plus software plus manuals/literature

https://item.mercari.com/jp/m34679356235/

Price conversion, plus proxy commission: $99.42 USD

Shipping/handling: $233.00 USD

Total value: $332.42 USD

The last one, complete with serial matching box, I won on Yahoo! Auctions for 6,000 yen ($54.00 USD by conversion), no keyboard or software/manuals though. #3: Just mouse, power cord, and keyboard/ADB cords: 

https://www.fromjapan.co.jp/en/auction/yahoo/input/t583103209?recommend=view&title=Macintosh Color Ciassic-II マッキントッシュ カラークラシックツー ジャンク品

Shipping/handling: I don't remember, through EMS though. 

Total value: $252.32 USD

IMG_6993.JPG

More often than not, I found myself picking these up not taking account of shipping cost. But these are the next frontier with me. I've become a fan of working on these now, when I was at first afraid of even taking off the back casing. I opened up the one I received today, just to make sure the grounding harness was securely installed. Don't wanna make the same mistake twice. ;)  

IMG_1929.JPG

I only have one keyboard to work with both of them, so I might try picking up another at some point. 

IMG_6997.JPG

None of the hard drives work at the moment. I've watched tutorials on taking apart SCSI drives and circumventing the sticky bumper head issue. I may try to crack one open soon. I eventually want to install some software on one and get it set up to actually use. 

IMG_7012.JPG

Literature that came with the second CCII: 

IMG_7009.JPG

Seems that the floppy drive on the one I received today has issues reading floppy disks. When I have time, I may look into figuring out what is the issue. For now, feast your eyes on this beautiful X

IMG_7016.JPG

Second CCII works fine now with the analog board from the first CCII: 

IMG_7007.JPG

All three motherboards that came with each unit. The 3rd worked when I first received it, but stopped working after I tried cleaning around the capacitors that appear to have leaked. I will probably sell it with the parts machine at some point. Only one of these motherboards has a 32MB Ram stick and FPU. 

IMG_6981.JPG

That's it for now.

You wouldn't be willing to sell me the nameplate from the broken CCII, would you?

I've upgraded mine with a 550 board, which effectively makes it a CCII, but it's still got a CC nameplate.

Very cool! I've never seen one CC II, much less..3!

Another member, @KnobsNSwitches, had actually messaged me about this earlier. I've just responded, but as I wish to send off the entire system (or at least entire thing without boards, analog and logic) rather than part it out piece by piece, he has first dibs. 

Ha, I sent him a PM with the exact same idea last night. I also have a 550 upgraded CC.


Apologies for the delay, you should have a PM in your Inbox now. I'm back in town, and hopefully I've address your question. Let me know what you think. 

Since it seems that the parts machine is the star of this topic, here are a few pics since I left him out of the group: 

Notice green tint to left side of display

Unit is much more yellow than I thought it would be, basing it off from the Mercari listing

Injuries sustained through the trip abroad

Plus some corner chips, just on front casing it seems. Back casing sustained some scratching, but I don't think from shipping? 

IMG_7043.JPG

Nameplate

IMG_7042.JPG

Here is the elusive defective/nonworking motherboard. It looks fine from here, and I can't figure out what could be wrong unless it just needs to be recapped. 

IMG_7046.JPG

Prior to cleaning it, the board worked (surprisingly?), even after I noticed there is obvious leakage from the capacitors. After I cleaned around them with 90% 2-propanol (isopropyl), the system would power on but not boot. Here is a pic of before the board was cleaned (and apparently still working). Notice how dusty it was! 

IMG_6540.JPG

Reverse of the same board: 

IMG_7049.JPG

So I tried washing the board over the sink with some soap, since I've read people popping these boards in a dishwasher and getting them back to working again (what???). Probably should not have done that, as some minute corrosion developed around leads/pads of the CPU that I could not clean out, and some other areas (more manageable to clean). I tried cleaning these as much as I could, but no matter what, I could hardly get the CPU leads cleaned. Anyways, still same result as before I cleaned under running water: powers on, but no operations beyond that. 

I guess, if my previous cleaning didn't kill the board, then washing under the sink definitely did no help: 

IMG_7050.JPG

IMG_7051.JPG

IMG_7052.JPG

IMG_7053.JPG

I kinda "Frankensteined" the analog board, trying to get the second CCII board to work again: I swapped flyback transformers first, thinking "Hey! What if the FB Transformer is burnt up?" I know, not a very safe setup. Don't try this at home, kids. 

IMG_6921.JPG

Okay, no change in results. Just used up the last of my desoldering braid. Serves me right :) So, what if the video board is burnt up to a crisp?? (desoldered from main board)

IMG_6963.JPG

Nope, that wasn't it. The swap did, however, improve picture stability for the working CCII, so I decided to stop here. Original flyback transformer and video board paired with donor analog board....fine, seems to be the sweet spot. That leaves the other board still not working, though, so I give up here. I will say, I used extreme caution every time I went back into the system, and always laid the system face down on a bed. Thank you, brave Youtube tutorial peoples. 

IMG_6952.JPG

At least it's good to know that the flyback transformer is good, and the videoboard works (somewhat unstable picture at times, especially at boot up just when you pop in a boot floppy disk, the image can show lines until it settles)

Maybe you were aware of this, and I'm not sure if it's needed, but did you try booting it with a PRAM battery?

Some Macs won't boot properly without one.
