John_A, Do you mean something like this? It came with a PowerBook 140 I bought a few years ago. This is the only example of a PowerBook coloured ADB mouse I've ever seen!

iphillips77, Welcome to the 68kMLA! One of the adjustments on the analog board should be a 'brightness cutoff' which dictates the maximum brightness that can be set via software. I am not too sure about the Colour Classic but I know that this applies to B&W Compact Macs. I hope this helps!

Hello all, I've just came across a document on the 68kMLA Wiki about 'Macintosh IIci RAM and ROM Pathways'. http://68kmla.org/wiki/index.php/Macintosh_IIci_RAM_and_ROM_Pathways It looks quite helpful for diagnosing trace problems but I don't know how to use it! Any help would be much...

Hello all, I don't think I explained the ROM SIMM situation this very well in my first post! My IIfx works fine but when I use its ROM SIMM in the IIci it chimes normally, then it plays the chimes of death. With the SE/30, which still suffers from 'Simasimac' after a recap and replacement...

Hello all, When I turn the IIci on I cannot turn it off via the on/off button. So I'll replace logic board capacitors under the PSU. I'll report back when they've been replaced!

volvo242gt, When I tested the logic board without the ROM SIMMS I did have the jumper installed next to the SIMM slot. With the IIci ROM selected I don't get a chime when I turn the Mac on. genie_mac, I have been checking the continuity for all the components within the area pictured. D8 is...

macclassic, It's nice to see your Classic running properly; there are a nice machine especially when you boot it from its ROM. Those full height drives always make characterful noises! Enjoy!

Hello all, I removed the oscillator, a Saronix 9029 50MHz, then and tested the logic board. Without the oscillator the IIci does not chime/chimes of death no matter what ROM SIMM is present. So I put it back under the assumption that it could be OK and any damage is only external. Could the...

Hello all, Earlier this week a Macintosh IIci arrived from Ebay that was described as having 'some corrosion on the power supply and motherboard'. I stripped the Mac down to check the the logic board's damage: a red Maxwell battery had leaked (thankfully the Mac was used on its side so the...

macclassic, To use the drive I'm my SE/30 I set the jumpers to SCSI ID '0' so the Mac could use it as a boot device. The data sheet that deals with drive specification and setting a SCSI ID is still available online. The drive was contained in a anti-static bag and its external condition was...

macclassic, I bought one of these drives last summer and used it in my SE/30 and it worked very well; I think they're NOS!

Hello all, I have replaced CR5 with the aforementioned component but I am still getting nothing from the Macintosh. Do the leads of CR5 and CR21 need to be in contact with the metal heat sink? I think I'll call it a day with this Macintosh for the time being! Thanks for all the help!

What an interesting find! But on a side note, would this prototype suffer the structural problems associated with mainstream 1xx series PowerBooks?

macclassic, Here is a diagram of the power supply for the Macintosh Classic II: https://drive.google.com/file/d/0B6j6P7lBWw-BVU5LZVA4SmRSTlE/edit?usp=sharing Also, for reference, the Macintosh Classic/II service manual: http://tim.id.au/laptops/apple/legacy/classic_ii.performa_200.pdf If the...

Hello all, I've transplanted the 157-0042C into the Macintosh but that has not solved anything. Back to the drawing board! Now, TDMS suggests the replacement of CR5 with a heavy duty MR824.

Paralel, Macintosh Plus Service Manual: http://tim.id.au/laptops/apple/legacy/macintosh_plus.pdf Within the manual there is a chapter called 'Adjustments' which has a section about focus. Maybe the focus dial needs some adjustment? I hope this helps!

Hello all, I've replaced all the resistors mentioned in a previous post and I am still getting nothing from the Macintosh. The 'Dead Mac Scrolls' points towards the Flyback Transformer as being as being a potential fault. The flyback installed currently is a 157-0026-B. Larry Pina says if the...

Hello all, uniserver: Thanks for spotting that capacitor! It has now been replaced. techknight: I didn't have any cans of compressed air so I gave the analog board a good scrub down with some rubbing alcohol and a toothbrush. I focused on the two components you mentioned. I reassembled the...

bigmessowires, At board reference CR20 there is only one hole. Larry Pina suggests a 'MBR1045' as a replacement part, which has two legs. A fellow member has photographs of such a analog board with the upgraded component. Pin three goes through the hole on the analog board and pin one is...

bigmessowires, At the moment I am busy working my way through your suggestions from 'Macintosh Repair and Upgrade Secrets'. I'll definitely source and replace the resistors that are mentioned! Also I have taken various photographs of the Analog Board for all to see...
