  1. It was my misunderstanding originally. I assumed that something else was needed, similar to the sleds that I have used for 3.5in drives with later Macs, and told reallyrandy that I was missing this piece. Note that Randy asked about a drive sled. This quickly (d)evolved into a discussion of hard drive carriers ... So - joethezombie was correct - hard drive just screwed to the carriage directly?
  2. oldappleguy, reallyrandy already has this bracket. See the photos in
  3. reallyrandy already has the hard drive carrier (which is part 805-0952, and looks to be different from 922-0066). What is needed is whatever came with the 5.25 inch original drive ... Looking at http://tim.id.au/laptops/apple/legacy/macintosh_ii.iix.iifx.pdf, which is where the exploded view came from, there are drawings earlier in the document that give some indication about what this was like or supposed to do (but not very informative).
  4. FYI - these macs found a new home. Went to a fellow 68kmla'er, who can self-identify if they want to. Never made it to Trading Post because my friends were overwhelmed trying to move their parents out of a large house with lots of stuff into an apartment, and were unprepared/unwilling to generate the necessary documentation and photos at the time. Once the move was over, they wanted the macs to move quickly. Apparently everyone involved was satisfied with the resulting transaction.
  5. Thanks everyone for the suggestions. I've never opened up any of these systems (I'd never touched any of these until last week) - I'll search for instructions, but are there any gotchas when opening them up that I should be aware of?
  6. No indication that they are interesting in doing ebay - I'll be helping with Trading Post or local only - and also 'as is'. Maximizing return is not their goal. Guess I'll look back through old Trading Post listings to get a feel for typical pricing, and try to adust accordingly for the condition. Thanks.
  7. Some friends want to get rid of 3 compact Macs of their parents that were last touched in 2001. They would like these to go to people who want to keep them going, and I volunteered to act as the intermediary here. I know nothing about Compact Macs, and need some advice on what information/leg work needs to be done before listing these on the Trading Post. 1) Macintosh Plus / 1MB M0001A Appears to work fine, booting off of an external HD. However, was not able to try it out since we could not find a mouse with the correct connector, nor an adaptor. (Again, I know nothing, so am not even sure what the options are here). Serial number indicates "Macintosh Plus (M0001A), ..., 6367th manufactured during the 23d week of 1986 in Fremont, CA". Has both the keyboard with integrated numeric keypad, and a keyboard/numeric keypad as two separate parts. 2) Macintosh SE w/Superdrive M5011 Works fine (with limited testing), and appears to have 4MB memory. Serial number indicates "Macintosh SE (B02), ..., was the 3842d manufactured during the 36th week of 1990 in Fremont, CA." 3) Macintosh SE/30 M5119 nonworking - powers up to a blank screen. Tried with external HD as well, and no difference. According to the note on the machine, same was true in 2001. Serial number indicates "9832d manufactured during the 5th week of 1989 in Fremont, CA." 4) There are a few peripherals (Mac N Frost fan + extra outlets; external HD; keyboards and mice, ???), but I did not try to document what was there. I will if there is something important that I should be looking. I don't know if any of these have any upgrades either - haven't looked, nor know what to look for or how. Thanks.
  8. Macdrone, thanks for the comments. I already found the jump start instructions, and Elfen also included the instructions in his last post. Batteries were replaced 3 years ago, so "should" be okay. If it becomes difficult to start again, this will be the first thing that I check. (Not excited about putting back in the old hard drive, but could do this to be able to reproduce the problem, assuming that this in fact was what caused the problem to disappear.)
  9. Thanks for the many thoughts. Since the problem has disappeared (for the moment) since I swapped hard drives, I'm leaning toward the power supply being the culprit (or perhaps the original hard drive is failing, though that seems like a strange behavior for a failing hard drive). To answer your question: > what doesnt it do? no clicks or power-on at all? Didn't do anything - no clicks or power-on at all.
  10. techknight - does this change your diagnosis of a possible problem with capacitors associated with the soft power circuit? What are the failure modes of tantalum capacitors - anything visible? Thanks.
  11. > Not the whole board but the 3 or so caps on the start up circuit, which will be in those little silver cans even if the rest of the board is solid state Tantalum caps. Where are these again? This is a Rev. A Mac II board. I've looked and don't see anything.
  12. FWIW - Changing SCSI drives seems to have solved my start-up problems. Perhaps the one drive was trying to draw more power at startup than the PS was consistent at providing?
  13. Thanks for all of the comments. Just to reiterate - it is not failing to start (yet), and the issue has not been getting worse over the last few years. I'll try the jump start test first, just to check that the replacement batteries have not started to fail prematurely.
  14. I have a Mac II that requires some coaxing to start up after it hasn't been used for a few days (or weeks). Once started, and then shut down, it starts up immediately when tried again. The initial start up issue can take 1 - 30 minutes before resolving itself (not especially accurate as I am annoyed at the time and sometimes give up and come back later and try again). Today (after being off for a few weeks), the first few tries failed, then I went and did something else for a few minutes, and it started up after the second try after returning. This appears to be independent of whether it has been plugged in while it is off, and it is not getting any worse. It has been this way for at least a few years now. Almost "feels" like there is a capacitor that needs to be recharged, and trying to start the system starts the recharge process. System has not been recapped - this is one of the early Mac IIs with the better quality capacitors. Last I looked, I did not see any issues with the board. I have not looked inside the power supply though. The PRAM batteries were also changed a few years back, though perhaps this needs to be done again - doesn't seem to represent a PRAM battery issue however. In any case, if anyone can explain what is going on, I'd appreciate it. Thanks.
  15. > buy at least 8MB of RAM. You don't need any more than 32MB and 8x4MB is not difficult to find. Going higher than 8MB requires some magic if you have an unupgraded Mac II. As mentioned earlier > 688851 MMU or an Apple Custom MMU chip you will need the 688851 to use larger than 1MB SIMMs. I just recently found (and purchased) 4x4MB SIMMs to raise my memory to 20MB, and I looked what seemed like a long time to find these. (I bought memory that did not work a few times before I was successful.) More memory is nice to have, though games that require more than 8MB memory tend to be too slow to enjoy on my system.
