Re: Strange IIci behavior, cont.

From: Jeff Grant <[EMAIL PROTECTED]>



The IIci has the Astec power supply, and I think you're right, it may
be getting quirky.  I have a bit of other odd behavior though.  I was
under the impression, (but could be totally wrong) that the Quadra 700
power supply would work in the IIci being the same form factor with
same listed voltages.  When I try my Quadra power supply in the IIci,
the light flickers again, but won't power up.  This happens if the PDS
card is in or removed.  Nada happens.  When I put the PSU back into
the Quadra, the 700 boots up just fine.  It happens to be the GE model
from the 700.  When I put the IIci's original Astec back in, it boots
up fine if no PDS card is in, as I described before.  So maybe it is
the mobo??  Maybe both . . . hmmm.  Oh yeah, I live in Fredericksburg,
Va.


There is a fairly common failure of the IIci motherboard which 
interferes with powering up.  Many of the surface mount capacitors 
are in the vicinity of the power-on circuitry on the motherboard and 
when they leak corrosive, that's the circuitry most likely to be 
damaged.


You may wish to pull your motherboard and examine the rear right 
quadrant for discoloration--slightly darker, hint of brown.


My IIci had this failure.  I ended up bypassing a motherboard trace 
with some wire, because one of the vias through which the trace 
passed was corroded completely.   I also cleaned the motherboard and 
replaced the caps.


You might try your IIci PS in the Q700 to see what you can see.

The two power supplies should be interchangeable.  However, the 
current required to power up might be different and that could be why 
one power supply come on and the other doesn't.  If the MB is 
delivering below spec. one PS may have more head room than the other.


Other compatible power supplies include IIcx, IIci, IIvi, IIvx, Q700, 
C650, Q650, 7100.


The PRAM battery is irrelevant to powering up on these models.

Re: dead IIci

[Manuel Marques]

I've checked the battery and it is completely DEAD - 0.01 V! Is the battery
vital to the startup circuitry? (the IIci only powers up by using the
keyboard button?). I'll try finding one in a photographic house tomorrow.

But I am still considering your offer, ajmoss.
Fares inside the EU are lower. And there are no customs.

Nope, isn't a Daystar. It's a TransWarp CI-50(Applied Engineering). I
haven't checked the battery yet... but I'll try, just to make sure it's not
the problem!!!

Oh, and it will RUN 8.1. I'll install Born Again, and they say on their
website that a IIci is compatible with it... ;-)

Get another motherboard, or another whole IIci that
works, then pop the cards in it.

Is that 50Mhz 030 a Daystar one? It needs the control
panel to enable the CPU and FPU on it. The 32K cache
always works on them. The Daystar cards are VERY
static sensitive! When not installed in a Mac, they
need to be SNUGLY wrapped in an ESD bag and not
allowed to slop and flop around with stuff like
foam pellets or Tyvek priority mail envelopes.

I got two formerly working ones in the mail a few
years ago, that were DOA because the static got them
even inside an ESD bag. The factory Daystar packaging
was a snug ESD bag then firmly strapped to a piece
of cardboard that fit into a box that allowed
no movement.

NEVER plug that card into anything but a IIci, IIvi,
IIvx PDS, or another Mac that has the Daystar adaptor.
Even though the card will physically fit onto the
mainboard of a IIsi or SE/30, IT WILL FRY without the
proper adaptor.

A IIci with a 50Mhz 030 (and 50Mhz 6882 FPU to match)
is very speedy.

It won't run OS 8.1 without a hack like Wish I Were
because 8.1 will not install or boot on any Mac with
a CPU older than an 040 or PPC.

It will be total Fandemonium!

Re: Dead Ici

[Manuel Marques]

I live in Portugal. But first, I'll try check the PRAM battery, then I'll
try getting a working IIci. I've already spent almost 50 euro on a new PSU,
let's wait and see. But thanks!!!

Where in the world are you? If you're within cheap mailing distance of
England 
I can send you a spare IIci that was working last time I checked it.

If you don't live in the UK, I can air mail you pieces of the computer, all
below 
2kg in weight, and that way stay below the weight limits of international 
postage.
