It's not true, but there are some Compacts that have them.  The FAQ has details.

The CUDA chip's initial parameters default to that date.

built them inside?... is this true? and which vintage macs did they do 
this with?

It's the birthday of the guy who designed the CUDA/PRAM system IIRC.

The later Macs seem to default to 1904 which changes to 2003 or 2005 if you 
use the up/down button. Not sure why that is :)

Most of the old Macs I've worked with have dead batteries (fortunately my
Iisi can keep time as long as it's plugged in, unlike LCs that need
batteries). Their clocks default to August 7, 1956. I guess the ROM has some
thing that tells Mac OS what time to use when the battery fails.

I could replace the battery on my IIsi, but it only loses track of time when
I move it and have to have it unplugged.

Re: Clock check. Re: OT: A/UX

[/dev/null]

speeaking of which

why is it that when Macs get y2k bugs or when the lithium battery goes ( 
i assume its that) the clock turns itself back to January 1945? they 
seem to have a unique way of counting... rather than going back to 1900...

my flatmate's LC II used to regularly say 1954 when he turned it on, 
then he'd re-set, reboot and it'd be fine...

there was a day when i put in a CDR of sound files i'd burned on a PC 
and when i read it into the mac they all came up as January 1945 or 
something weird...

i wondered if it has something to do with the point at which small ints 
cycle back round to 0 ?...
