Wow, I never knew there was a PowerPC with no ethernet, and no Geoport! And it was made not only after Apple started reducing costs moving to IDE, that thing even has a standard PC floppy drive rather than the old multi-speed auto-inject superdrives that were on most mac's made before 2000. Was it below $300 when it was new?
Moving the drive as others have said should work.
Or if you don't want to open the thing up, the good news is the printer and modem ports are standard RS-232 serial, and have been capable of 230kbps reliably since the first AV macs (the Geoport which that thing lacks is an RS-232 serial port capable of going above theoretical USB1.1 speeds) but you need a cable to go either between the 2 macs or from mini-din 8 to a PC's DB-9 serial port. Appletalk networking will also work between the 2 mac's serial ports using a serial cable, but the 2 computers must be positioned at the same height (really!) for it to work without an Appletalk adapter due to some very bizarre signaling.
I'm going to wager that they don't have any terminal software on there to download through that port though.
Some of the specs on that link don't make any sense BTW, for example, if it really has 1MB video ram, there should be a lot more video modes allowed. The highest it lists use less than 512KB.
