>What might I do with those? I do have a machine running Windows XP that has a diskette drive
It depends a bit upon the operating system installed on the Macintosh IIsi. With a relatively new system (like the downloadable 7.5.3) PC Exchange may be in the Control Panels folder, allowing transfers to take place on PC-formatted floppies. With System (7.0.1 or) 7.1, the supplied (on the Tidbits system disk) Apple File Exchange application can be used in order to achieve a similar result. Otherwise, one can install a utility such as TransMac (which handles Mac-formatted 1.44 MB floppies) on a Windows PC.
>Modem port. But it requires an external modem and then I'm not sure what I would do since the IIsi doesn't speak IP.
IP is not necessary. You could set up a direct null-modem link between the Modem Port of the IIsi and the serial port of a PC. The cable can be a combination of a Macintosh modem cable (MiniDIN-8M to DB-25M) and a standard PC-style null-modem cable (DB-25F to DB-9F). Communications software would be needed on both computers (for example, the communications part of ClarisWorks on the Mac and HyperTerminal on the PC).
>SCSI. Is it possible to get something to attach to the SCSI chain (cheap) that would do the job?
Handling SCSI devices directly would require that the PC can be made SCSI-capable (not always easy). An indirect solution, involving a SCSI Zip drive at the Mac and a corresponding USB Zip drive at the PC, would per se be possible, but not exactly cheap. SCSI-to-Ethernet converters/adapters exist, but can be difficult to find (and you may still face problems with networking protocols).

I really appreaciate the help!
I booted up and it has 7.0.1. Before I could proceed further, everything froze up on me. On subsequent boot tries, I just get a blank screen with a pointer that I can move with the mouse (once or twice that froze up) and nothing else - no sounds, no happy Mac face. Happens the same way with or without the external SCSI drive attached.
So now I have to go figure out if my IIsi has finally given up the ghost before I can proceed further. I'll check in here if/when I get it running again.

Not even the startup sound? This is a bit confusing. It may be worth checking in which condition the logic board 3.6 V battery is (should read at least something like 3.2 to 3.3 V). A bad battery can sometimes cause strange problems.

You might try reseating the ROM and RAM modules - they are socketed with little tangs on either end, and connections can become be flaky over the years. A little mechanical back-and-forth sometimes helps. Unless you want to take up a new hobby, I'd go with Jan's suggestion of getting a PC-compatible floppy going. How to interpret your files once they're off of the Mac will be the next trick.

A new battery didn't change the behavior, unfortunately. Nothing looks amiss on the motherboard, at least as far as I can tell. All of the removable modules feel like they are seated firmly.
I know someone who has a RATOC USB-to-SCSI converter. I'm trying to figure out if that would work. Any thoughts are welcome. In particular, can Mac OS X read the file system (HFS, I believe?).
Currently Being ModeratedFeb 24, 2013 4:28 AM (in response to jjkraw)
If the external SCSI hard drive is OK (and with an appropriate cable/adapter and terminator), it looks like this converter could be useful. However, since SCSI is not always easy to work with, it may be wise to look upon this as an experiment. Do not risk anything if your files are important. If you wish to retrieve files on the internal hard drive, it may be possible to move this drive to the external enclosure. One of your Mac OS X computers should be able to at least read the file system.
It would probably be better and safer if the Macintosh IIsi, somehow, can be made to work. This is especially true if it will become necessary to convert file formats (using Save As) in the original programs before exporting/transferring files to a modern computer.

I wouldn't totally disqualify the capacitors, even if there doesn't *seem* to be any leakage on the motherboard. When the caps leak, it should look like a thin film of spilled Coke on the board.
You should also try booting the IIsi with the hard drive disconnected and any installed RAM SIMMs removed from the board. It's not common, but faulty RAM can result in no chime/grey screen (I've had this happen on my IIci before). Hopefully, the IIsi will bring up a flashing question mark and from there you can isolate the problem to either of the two.

The first question to ask is if you can hear the hard drives spin up to speed and if you can hear any chatter as the drive heads move back and forth to access data. If not, your drives have decided to freeze up. It seems unlikely that both drives would do this at the same time. If you were booting from the external drive, maybe the internal drive was not working at all and the external simply took over the startup process. Until you hear the drive spin up, you have no data to recover.
The second question to ask is a software question. If the data you want to preserve is something like a Quicken file, you will not be able to access it from newer software. It is best to use the original software to save the data as text or ASCII or SYLK. Then newer software will recognize the information.

I appreciate all of the replies. Other things in life have forced me to put this project on the back-burner, but I did fire up the IIsi today after having it unplugged and doing nothing for almost two weeks. Here is what happened:
First try: Happy boot!! I got the happy Mac face, the Silverlining image from the Q drive, and once booted was able to access both disks via Finder. I could not find Apple File Exchange on either disk, so I inserted the Tidbits diskette. I went into the folder and double-clicked on the application. Shortly after, the display froze up. I pushed the button on the back of the IIsi to shut it down.
Second try: Booted again, spit out the diskette, both hard disks functional. This time, I inserted the Tidbits disk and attempted to copy the Exchange folder to the external Q drive. The display again froze during the copy operation. Shut it down again.
Third try: White screen, no happy faces, no cursor arrow, nothing. I shut down again and also power cycled the Q drive.
Fourth try: On power-up, I'm getting what looks like a fabric pattern on the screen with a few different colors. That's it.
So, I've unplugged everything again and am off to other things for the meantime. I have noticed that only after the system has rested unplugged for a long period of time (at least a day) that I can get this far with it. Once it "warms up", it never even gets to accessing the disks.

>Once it "warms up", it never even gets to accessing the disks.
I suggest that you take another close look at the logic board. Use a magnifying glass. Are there any bad solder joints? Discoloured or cracked electronic components? Check whether capacitors are bulging or leaking.

Thanks, Jan. There is one section, just to the right of the SCSI cable that goes to the internal drive, that looks like it has an uneven sheen to it, as if something sticky had been spilled on it. There is a capacitor (C34) in this area. A magnifying glass reveals a lot!
