Thank you!  That helps greatly.  I saw the lifter handles but it looked
as though there were a single board all the way through the machine.
(I found a work machine I could fetch that page from - odd, that
something calling itself "the retro web" would desupport HTTP.  Oh
well, I did find a work machine to fetch it with.)

I've now replaced the battery.  Now there's another issue, leading me
to wonder if I managed to break something in the process.

Before I replaced the battery, when I was using a fast power-cycle as a
reset, I netbooted at least three times and from disk at least once.
Once it loaded the kernel (which failed for at least one netboot), it
was fine.  Now, it panics early in autoconf, regardless of whether I
boot from the net or the disk.  The last working boot, before battery
replacement, looked like

>>>boot dkd0.0.0.1010.0

I've tried three boots, and there is slight variation.  The last few
lines of the other two boots are

and

I notice BROKEN_PROM_CONSOLE, which controls that test, is gone in
5.2's version of that file; I would tend to just try 5.2 instead, but
when it "worked fine" before the battery change I have to wonder.

I'm going to try reseating the board I removed/reinstalled....
