Should be no problem for the swap. both use SCSI hard disks and 30pin 
simms. The IIci has 8 simm slots. I can't help with your other question 
- sorry.

Is the startup delay from power on to click activity or time to accept the power
on command (furiously hitting the power up key) ?

If it's the first, I'd re-install software, de-frag my hard drive, re-build the
desktop, and clean out my extensions folder of old stuff.

If it's the second, replace the battery ($10 at Radio Shack).

Yeah, but if you can find the battery elsewhere, do so.  I'd think mac
guys would be as dismayed by Radio Shack as they are by Microsoft, or at
least I'd hope they would.  Try to get that battery from a mac dealer,
put your dollar support where your os heart is, not is Radio Shack, the
Seven-Eleven/McDonalds of electronics.

The IIci wants faster memory chips than the IIcx, but I have rarely had a
problem switching memory between the two models.  Almost all the hardware
is the same (except the IIci has internal video) but some of it is faster
on the IIci.

I have seen two IIcx and heard of one IIfx taking L-O-N-G-E-R to start up,
by which I mean that the time between pressing the power key (either the
one on the keyboard *or* the one on the back of the case) to the time of
hearing the startup chime goes from several minutes to eventually 45
minutes.  After the chime, everything is normal speed, and no hardware
errors detected by any diagnostic I could get run on it.  I tried
replacing the power supply.  I tried replacing the motherboard battery (I
got the battery from Jameco, http://www.jameco.com/).  I tried the weird
suggestion of having everything unplugged from the wall until I wanted to
turn it on (no soft power, no trickle from power supply to keyboard to
respond to keyboard start), but that if anything made it take longer.  I
had a sense that temperature was a contributing factor to startup time but
not the only or even major one.  I exchanged monitor, keyboard, and mouse
for known good and newer peripherals.  *None* of those fixed either IIcx. 
So, at the time, I got a IIci instead.  If anyone has an answer to the
delay between asking a IIcx to start and the startup chime, I'm _CURIOUS_!

Your logic board is probbably defective. If the filter caps start to leak,
the board has erratic or no start up. The simms and hd are directly
replaceable.

Yes, the parts are generally exchangeable between the 2 Macs - SIMMS, hard
disk, floppy drive, power supply.

Speaking of the power supply, the IIcx and some early model IIci's had
this problem of starting up.  A simple solution was to replace the power
supply - costly through Apple, but cheap if you can get one from an old
IIci/Quadra 700/IIvi/IIvx/PM7100 - all use the same power supply.  The new
power supplies that fixed the problem are of a 112w and I think the old
ones were an 84w.

I hope this helps.

My old IIci wouldn't boot up once a time. I opened it and finally found
that fluid from the battery went over the motherboard. Althought it was
very little, it made the power-on circuit defective becuase it oxidated
some parts.

Also, I had to replace the ROM chips in my MacII years ago beacause it
only bootet 3 out of ten times. But since ROM chips aren't quite cheap,
I'd try to swap them first - *if* you are familiar with such a
procedure.
