Hello everyone,
As the subject line says, I'm wondering if anyone has installed an SSD in their G4? If so, would you please offer recommendations and comments on how it performs?
Thanks,
Bill

2.5" SATA to PATA converters certainly exist (find them on eBay), but how
would one provide the "trim" function?

There is no need for the trim function. It is beneficial, but works
without it as well. It is said that SSDs with a SandForce controller
have a very good garbage collection algorithm, but I assume that every
modern SSD has a good one.
If the SSD is used without trim, it will rely on this garbage collection
only. If you don't shift huge masses of data around you should be good.
Make sure you keep some empty space for the controller to work with.
E.g. if the SSD has 120 GB, use only 100-110 GB of it by either
partitioning a smaller partition size than possible, or by making sure
that the filesystem is never completely full, i.e. at least 10-20 GB
should always be free space. The partition method is better without trim.

I cannot speak specifically for the Macintosh side of things however it would appear that TRIM is capable of being passed through IDE. This happens to be through IDE to an MSATA style SSD. I would imagine that this would translate roughly the same in using a program to issue a trim command to the drive if the OS version does not natively support it and if it does I would presume that it would recognize it as an SSD and pass the TRIM command appropriately. :)

I haven't done it myself, but if you're using a SATA SSD, even the
cheapest and slowest one will more than saturate the IDE bus, and should
be noticeably faster than a IDE spinning disk. That bus is much
narrower than even a slow SATA bus, though, so don't expect too much.
I have considered using an IDE Disk-on-Module SSD in my iBook G3 (specs
in sig), but at this point, it feels like it would be throwing money
away, since it's effectively useless now as anything other than a novel
talking point.

I have used an SSD in my Quicksilver for at least a year, to great satisfaction. It's not night-and-day, but definitely worth while ( the system has slower bus and port speeds, so the speed up is not felt as radically as with newer systems). It does boost the overall performance of the system noticeably, most especially with data-base intensive applications like Mail and Vienna. I have always used SSDs from OWC (macsales.com), which can be purchased as a kit with the right ATA to SATA adapter ( I have used a generic adapter at times too).
Just remember to get the one they list as compatible ( the 3G Legacy as I recall ).
You can use any of the offered sizes, but only the first 120 or so GB will be seen by the Quicksilver, (the drive can always later be used in another machine at full capacity).
So if this is your main machine, it is worthwhile.
Also remember that SSDs will have a shorter lifespan than hard drives as to the number of writes, so it's best to use them for boot drives, rather than data drives.

137,000 MB is the limit for an early QS.
Late QSes have this limit removed in hardware.
"-02" IDE chip has the fix for large drives.
Early QS's O.F. can be updated with the > 137,000 MB firmware alteration,
which is permanent on these machines, and remains until the O.F. has been
reset.

> 137,000 MB is the limit for an early QS.
Oops ... the limit is 131,072 MB, computed as follows: 128 megabytes
(where a "megabyte" is really 1024-based, and not 1000-based) = 131,072
MB.
The problem is: the early QSes support only a 24-bit LBA size, whereas
late QSes support a 48-bit LBA. The difference is in the ROM, so a hybrid
machine, say, an early QS with a late QS motherboard, can be treated as a
late QS.
Application of the O.F. hack forces the early QS to use 48-bit LBAs, hence
large drives will work in those cases.
I HIGHLY RECOMMEND partitioning your large drives with 128 MB as the first
partition, and the entire remainder of the drive as a second partition.
In this way, your drive will be compatible with old or new QSes, with or
without the O.F. hack, and the only downside is the second partition will
not be seen if LBA48 is not being used.
Heck, you may even use such a large drive as your boot drive.

I'm pretty sure I tried that without success -- i.e. It is an issue of the drive size on the ATA bus, not just volumes. In any case I eventually mounted the SSD in an external FW bay and boot/operate from that, as the FW connection is at least as fast if not faster and also not subject to that size limit.
