- I'm not sure this is the right place to seek help but I've had a real nasty
- problem with my MAC II ever since I bought it in June , '88. It has a 60 mb
- hd. After I bought it I had a 2nd meg of RAM installed and that's when my
- problems started. Every week, I would turn my MAC and it would fail to boot
- and crash. The dealer could not diagnose the problem. They installed a new
- logic board but that didn't help. finally in Sept. they gave me a new CPU.
- They changed some but not all of the chips because they found that the 2 megs
- were running at slightly different speeds (altho not at to much a variance to
- be the source of the problem in their opinion. They did not change my h.d.
- (which, by the way is a CMS h.d.) All was well for a month. I had one document
- freeze when I went to save it and lost it on restart but that was it. Then, in
- late Oct., I spent the day working on the MAC. Part of the time I spent
- downloading sound files off a local MAC board. Late that day I went to open a
- document in Word and the machine froze. WHen I tried to restart, the machine
- would not boot. After several restart attempts which failed, I shut down and
- when I started up again, all appeared well. But then, when I tried to open
- documents in various applications, the machine would freeze. I tried a pram zap
- but that didn't help. Things went from bad to worse and before I knew it, I
- had lost my h.d. icon. I took the machine into my dealer who kept it for 2
- weeks and said all he could find wrong was a "damaged directory." My gut
- feeling is that the problem had something to do with my sound files (I was
- working with System 6.0, which I understand had some nasty problems with sound
- files>) I now have system 6.02. I'm going only on gut feelings and I have to
- admit that it doesn't make sense that my crash happened many hours after I
- loaded the sound files into my system folder and activated them but who knows.
- I'm sort of hoping that's the cause because otherwise, I'm headed for another
- undiagnosable crash and if that's the case I'll toss this thing out the window
- and buy and IBM

- The two key clues in your message are: (1) The problem started when you
- installed an additional 1 Meg of memory (using 256K SIMMS), and (2) "they found
- that the 2 megs were running at slightly different speeds".
-
- I take this to mean that the original Meg is 120 ns memory, while the second
- Meg is 150 ns memory (which is more common in the 256K size). 150 ns memory
- WILL NOT WORK RELIABLY in a Mac II. Take it out!

- MAKE SURE YOU RAM IS AT ALL THE SAME SPEED. 120 NS or better for a Mac II. It
- sounds like this may be your problem. It also sounds like you dealer is
- treating you like a pain in the ass ("I took the machine into my dealer who
- kept it for 2 weeks and said all he could find wrong was a "damaged
- directory.").
-
- Sound problems don't cause the sort of problems you are having. Your problems
- are either, corrupted files (such as your system file), or hardware
- failure/incompatibility. Since your problems started when you got the 2nd Mb,
- I'd point to that, and the speed differences might be the cause.

- This (the Mac II not recognizing its hard disk) happens when the parameter RAM
- gets clobbered a certain way. A fix to this problem was built into System
- 6.0.2, so you should upgrade.
-
- You can fix it by zapping the parameter RAM. Hold down the [Option], [Shift],
- and [Command] keys, and invoke the Control Panel. You'll get a little dialog
- asking if you want to zap the PRAM. You do. After this (you may have to do it a
- couple of times), your machine should boot from the hard disk.

- Kaku,
-
- Most likely the crash did bad things to parameter RAM, where certain basic
- information is stored. Boot the Mac. Invoke the Control Panel while holding
- down option, shift, and command keys. You'll get a box asking if you want to
- reset parameter RAM. Say "yes." Then reboot.

- I had the same problem with a Mac II, new in June '88, with a CMS 60 meg in-
- ternal hard disk. I bought the second meg from the dealer separately.
- No way the Mac II would reliably boot from the hard disk, despite what
- the CMS dealer said was a patch that properly worked with System 6.0.
- Now that I read your message, maybe it IS the extra memory speed. Does
- anyone else have this problem? I finally exchanged for a Rodime 45 meg
- internal drive, which worked great until recently I got PC Tools Mac
- (upgrade to MacTools) and sometimes I can't even dump trash. Things
- hang unpredictably and I was considering defection to IBM like you were.
- If the memory was the problem Please send me E-mail and let me know.
- Thanks.
