Hello everybody!  This is my first post, but I have been lurking for a few months now.  It's good to finally join!  I have been wanting to get back into the world of Vintage Macintosh for a while now and finally scored a sweet LC550 from a recycler.  She is running System 7.1P5 and works pretty well!  I plan to eventually recap and upgrade this machine, money permitting.

I was wondering if anyone had any experience with FPU upgrades.  Can the ones on eBay that ship from China be trusted?  Do they do anything besides look cool in the expansion socket on the LC motherboard?  Would they help SimCity 2000 run any better?  (it runs very slowly at the moment)  Does anybody know if I need a 68881 or a 68882, and which speed?

The Quantum HDD in the machine is also half-dead.  It often refuses to spin up unless I pull it out of the machine and let it sit in the sun for a while.  Once warm, it spins up and works until I shut it off again.  Does anyone have any experience with the SCSI2SD adapters?  How are they speed-wise?  I'd love to hear any input/stories/experience you guys have with them.

Thanks everyone  :b&w:
