The PET ROMs are mapped like this:
$9000-$9FFF This is an expansion ROM area. Some programs need a kind
of dongle-ROM for copy protection in this socket. This was annoying
when different programs needed different ROMs in the same socket...
$A000-$AFFF This is an expansion ROM area. See above ($9000)
$B000-$BFFF For the original ROMs and the upgrade ROMs that start at
$C000, this is an expansion ROM area. See above ($9000). For the 4.0
ROMs, this is the first part.
$C000-$DFFF BASIC ROMs (two with 4k each)
$E000-$E7FF Editor ROM (in 4.0 ROMs, normal system ROM area otherwise)
$E800-$EFFF I/O area (PETs without CRTC), see below. For PETs with
CRTC (Fat-40 and 8032) the I/O area is 256 byte ($E800-$E8FF) and
the rest is either open address or the $E*** ROM iff it is 4k.
$F000-$FFFF Kernel ROM
(courtesy of André's PET index).
You can dump everything except the character ROM with just peek.
Actually, you should be able to start it from the built in monitor.
Anyone know the commands?

Yep.
