I also got a couple of QuickSilver 2002s recently, if you like tinkering with older stuff they are great.
Put a OS 9 install in and head over to Macintosh garden, lots of classic software to pass some time on a cold day. Also grabbed a old CRT monitor as the older games run at lower resolutions that look better on a CRT I find than scaled down on a LCD.
The speed of the older machines does not matter much for OS 9 stuff, your 733 is fine.
Next I want to find a Cube to add to the collection.
Many judge them on how they run today's software, but to me at least that is not the point.
I have machines that can run today's programs fine, but it's neat to have some classic macs running software from that era.
