  1. Mac IIsi SCSI CD boot issues

    I have no constructive advice, but I love your profile pic - "Let's go to my room pig!!!"
  2. Apple IIe without disk drive

    OMG - that is so awesome! These are magical times in which we live. I have to fire up the Apple][+ to try this out.
  3. Macintosh Portable battery replacement

    I cannot stress enough that this is a fact - DO NOT attempt to start the Macintosh portable with anything other than the correct charger and both fully functioning batteries. Oh, and test the Macintosh portable's correct charger to see if the output voltage is correct - some of them need to be recapped by now. The first one I bought died from this exact scenario, before we knew it was a thing. Its too bad that bad information on the internet can't be rescinded or at least annotated. New folks are going to keep finding this bad advice forever.
  4. Makes me kinda glad that I don't have a key to trip me up on my 900.
  5. Upcoming items in my collection

    I loved those books! I remember going to B. Dalton and reading through the Inside Macintosh: [insert favorite here...], when they first came out, until I had saved up enough money to buy the ones I needed. Very helpful at the time and I still have mine on the shelf. I hardly ever look inside them these days (I mostly use the pdf versions, when I want to read them). Congrats! I'm envious of the lampshade Mac and I miss mine, even though it had started to do the occasional red-shift thing.
  6. Macintosh Plus Chirping Noise

    Please take one good high-res shot of the outside of the analog board and another hi-res shot of the inside of the computer, showing as much as you can of the CRT, cables, etc. So far, most of the small items that you have focused on have turned out to be alright, so it might be helpful to look over everything, including the current symptoms (if you could list them) and work our way to a diagnoses. Oh, and be super careful not to touch anything while its plugged in or running.
  7. The other battery is there in the picture, barely peeking out from behind the last (first?) SIMM. Could you post a hi-res picture of the MB from directly overhead and also one of the ROM and SIMMs with the part numbers showing? Did it come with electrolytic caps? Did you replace all the caps, including the axials? Did you wash the board?
  8. I use my Apple CD 600 together with the Apple Legacy CD to boot and then install the Mac OS. I used it last week with an LCIII.
  9. Fitting a SCSI2SD in a 68k Mac

    Yes, it was formatted as HFS standard (the other option was greyed out). So, I didn't pursue the troubleshooting steps in order, but I did do the following... Attach power to the molex connector - this one didn't seem to matter. After writing the settings in the scsi2sd-util, read them back - I had already checked this, but a good reminder, I re-checked the settings. Make sure the SCSI2SD isn't shorting out on the solder side - I had seen a few mentions of this, so I was using an envelope until I got it working and found a more permanent solution. Try using slightly less than 256MB on the 256MB card, like 225MB - I liked this idea (one of the easiest to check) and set the device size to 254MB. This worked (changing the card size) - I formatted the card and it stayed through reboots, so I installed 7.5.3. Works great so far. This solution also explains why the last partition on the other card worked, as there was extra space on the 16GB card after the 4th 2GB device partition. It seems that it needed a few MB free on the card so that the OS didn't misinterpret the size. I have a few more experiments and a little more research in mind, to clarify the rules, but I would like to say thanks, both for putting together this thread and for the responses that helped me to get mine working.
  10. Fitting a SCSI2SD in a 68k Mac

    I am a bit envious that everyone is getting these to work. I have a couple of V5 SCSI2SD that I cannot get to work with an LCIII. I boot the LC from a SCSI CD (ID 3 that is properly terminated and running the Apple Legacy CD (boots to 7.6.1). Since I have two of them, I have tried setting them up in a couple of different ways: First, I updated the firmware on both. The first one had a 256MB SD card that came with the device when I bought it, the other has a 16GB Lexar card that I'm using with it. I started the card utility and set them as described above .i.e. set the vendor to the string " SEAGATE" , product ID to the string " ST225N", revision to the string "1.0 " and assigned the first to a SCSI ID of 0 and the second to SCSI ID's of 0,1,2,4. (see pics below - I later attempted to use the QUANTUM FIREBALL* settings on the 256MB one and combined all the tabbed settings that were different in the pics, to simplify them) I attached the card (the 256MB equipped one) to the SCSI cable and started the LCIII and initialized the device, using HD SC Setup. It completed initializing, so then I used Drive Setup 1.7.3 to partition the drive (1 partition - 242 MB), renamed it and had a drive icon on the desktop and when it was opened it was the right size (a little less than 250MB), so I rebooted and there was ... nothing. I checked in Drive Setup and the device was seen on the SCSI bus. Attempting to mount the device yielded the following dialog box that explains the problem, but based on what I saw in the Finder, before the reboot (it mounted with the correct size, well under 2GB, let alone 4GB), so I don't understand what setting is causing the issue. Re-initializing made the drive show again on the desktop and allowed me to install 7.5.3 off the CD, but since it doesn't show up after the reboot, there is still an issue. To add a bit more complexity, the 4th device on the 16GB card does mount on reboots, but none of the other ones do. Has anyone come across this issue and have advice?
  11. I also have 3 dead ones squirrelled away to either repair someday, or to harvest for parts. I don't need a replacement yet, but I am watching this thread with great interest.
  12. Mac IIx C3 value requested

    Thank you superj2000, very much appreciated!
  13. I recapped a IIx board a very, long, while back and thought I would fire it up tonight. So, I hooked up a monitor and keyboard, pressed the power button and ... nothing. I opened it up, checked the batteries that I had put in it when it was recapped (probably over a year [or two?!?] ago) and both were practically dead. Since it had one of TT's battery boards in it, I put in some nice, newish, fully charged batteries and I tried the start button again and ... nothing. Since it had been a while, I looked up how to 'jump start' a Mac II and when I performed that procedure, the Mac booted right up. While taking a look at things, it looked like C3 was not installed, so I checked the internet to either find pics of the cap that listed its value or the value itself. I can't believe that I did not install one, when I recapped the board, but it is just a set of clean holes where the axial capacitor C3 should be AND I cannot find the values (I would like both uF and voltage). If anyone either knows what it is, or can check their Mac IIx board and pass along the values, I would appreciate it. I did find copies of the II/IIx startup circuit that list it as 47uF, but I would appreciate an answer that is based on what was physically installed or successfully used as a replacement.
  14. I don't know if re-capping will fix the issue, but it needs to be done and it will give you one less issue to be concerned with. When I get a 'new' machine that needs caps, I don't even turn them on, prior to re-capping it. My theory is that if there are no errant voltages from the bad caps, then there is less chance of issues occurring downstream. I do this with machines that historically need caps e.g. SE/30, LCIII, Mac II, etc.
  15. That is good information - it helped me, since I had been wondering about Apple ][ booting, after getting a couple of them last year and testing the drives. I thought that this might be the case, but had not looked into a definitive answer.
