Yep! That's huge. About twice the size of a D9090.

Cool. Do they have a web/ftp site, or do you have to get
physical disks from them?

I have a device I got from Marko Makela - the C2N232
http://www.funet.fi/pub/cbm/transfer/C2N232/C2N232.html
It's a microcontroller that plugs into any 8-bit C= cassette connector
(PET, C-64, VIC-20, etc) and speaks RS-232 out the other end. I have
tested mine with a VIC-20 and a W2K laptop. I still owe Marko a test
with my 2001-N once I get it working reliably. You can use the
ordinary ROM tape routines for the C= side, or you can download a
faster utility that knows how the C2N232 works.
I think they are around 20-25 Euros.
Another option would require a 1541 drive and an X(E)1541 cable, and
a C= 2040/3040/4040 drive. You write the disk from the PC using the
1541 and the parallel cable, then read the disk in the PET with whatever
native drive you have. If you lack the drives, then a C2N232 is probably
the cheapest way to go. If you have the hardware, even if you have to
make the cable, then _that_ is the cheapest way to go.

Cool.

Interesting. The D9060/D9090 has one board that has a 6502 and (IIRC)
6504. The 6502 runs the Commodore DOS and speaks IEEE-488. The 6504
speaks SASI to the next board, which is SASI<->ST506. The drive is
a 4 head or 6 head Tandon drive. Others have had good luck with
installing a newer drive with the right number of heads, like an ST225
or ST241.
Be neat to see how the Shark works. Was that a UK product?
