I'd poke at it with BLU or NeoWidex and check the status of the drive as this will give you more detailed info, but yeah, reinstalling the OS seems like a good next step.
And most importantly, congrats!

Thanks! It feels great to get this lucky with an "untested" ProFile from eBay! Now it's just a matter of replacing the RIFA caps in the PSU and the ProFile will be fully repaired.

Good idea. I'll give that a shot once I get the floppy controller fixed and can boot from a floppy disk. The tracking info says that the 6504 just departed from China this morning even though I ordered it a while ago, but hopefully it will be here soon!
Do you think it would be worth trying to recover any data off the ProFile before formatting it? This would be tough since I'm almost certain that my serial ports don't work due to corrosion on the motherboard so I couldn't image it with BLU, but it would suck to accidentally erase some sort of rare or prototype piece of software.

If your serial port is working, there is a way to type in a mini loader into service mode and transfer BLU over the serial port. You could use that to both probe the status of the ProFile *and* image it to see if there's anything there.

Based off the amount of corrosion on the resistor packs on the motherboard that connect to the serial ports, I highly doubt that they're working. I can buy a serial cable to try it out, though. I would just need a DB9 to DB25 null modem cable, right?

Yes, that (null modem cable) and a new Lisa ;)
