I run the following configuration: Mac+ with 2.5Meg (generic), Peak-80+
with OS-6.0, a bunch of INITs, etc ... but I don't think I ever get that
far when .....:
The latest horror-story in my "Sundays with my Macintosh":
After I Shutdown and power-down and get some sleep, I will get up after
my usual nightmares featuring prominently my Macintosh, mingling with
the various candidates for political office....
...and I will power up my home-computer center, only to be greeted by
a SadMac with code 020020 .... (it's been happening ever since 6.0)
the Mac-screen does not even show the expected delay of the memory-test
performed by the ROM-code at cold-boot.
but, get this, when I boot from my OS-6.0-boot floppy I have prepared
for such emergencies, Minny, after the appropriate blank screen and
delays taken up by the ROM-originating RAM-memory-test,
shows a "smiley" and gives me a DeskTop with Peak mounted, thank you kindly.
it gets stranger: I Shutdown, the floppy gets ejected, and reboot from
the Peak-80+ works just fine (without the delay for the ROM-memory test,
of course); Another ShutDown, and power-off of Peak and Mac to force the
ROM-memory test ..... works just fine, even after a Power-off of several
minutes ...
Now, rumour has it, that the voltage which maintains the PRAM-values
in RAM somewhere takes between 5 and 10 minutes to dissipate enough for
the values to be lost; after which the battery maintained PRAM-values are
needed at BOOT-time...
Could it be that I am looking at a bug in OS-6.0 or is there an explanation
for this difference in behavior between booting from floppy and booting
from Hard Disk centering around a "too old" battery, or, possibly,
something wrong in the software or hardware of the Peak ...
the problem worries me more than it, actually, irritates me ....
Anyone with a good answer is urgently requested to post a follow-up;
anyone who just likes to speculate and kick around this topic is invited
to send me E-mail ....
PS: yes, voltage is adjusted to 5.0V; no, OS was not "installed", but OS-5.0
was removed from Peak before OS-6.0 was copied onto the Peak (BTW,
I am under the impression that the BOOT-block version-number was
not updated by this process and I went in with FEdit+ and changed
it "the hard way")
