I just got the same computer and is in the same boat as you. I wasn't able to find the recovery CD but I did found (what seems like) the driver installers.
I have yet to test these files myself but they seem legit. Plug one of the link below into the Wayback Machine and go to a capture to download!
The file to get depends on your machine revision, H1A, H1B, H1C, you can determine this from your computer serial number.
I think XPT is for WinXP, 7X86 is probably for Win7 32-bit? Try them all, if anything.
ftp://ftp.panasonic.com/computer/software/H1A-MK1-XPT.exe
ftp://ftp.panasonic.com/computer/software/H1B-MK1.5-XPT.exe
ftp://ftp.panasonic.com/computer/software/H1B-MK1.exe
ftp://ftp.panasonic.com/computer/software/H1C-MK2-7X86.exe
ftp://ftp.panasonic.com/computer/software/H1C-MK2-XPT.exe
If you go to "ftp://ftp.panasonic.com/computer/software/" in the Wayback Machine, you can browse the directory to. It will download a text file with the listing, just open the downloaded file in text editor.
Hope this helps, I'm waiting on the 1.8in drive to come in. Good luck!
