Or a simplified version that should work on all assemblers:
http://singularcrew.hu/temp/1520-01-plain.asm
http://singularcrew.hu/temp/1520-03-plain.asm
But these are temp locations and the disassembly is still being refined, so I would
caution against grabbing these now and not checking back later.
Binary:

Infofile (pretty basic):
https://dl.dropboxusercontent.com/u/58002657/cbm/1520/p8-pf.infofile
Raw disassembly (infofile still crude):

The above is only the -01 binary. I can send the -03 files, but you'd
need to stitch them together (I could only dump them in 256 byte chunks).
At some point soon, there will be a web page someone is creating to put
all of this stuff in a common location, including the binaries and a
schematic to dump them yourself.

Just an update
to note that I was successful in reading the ROM out of
the MOS 6500/1 using the test mode. I used an ATMEGA32 to drive the
Well done!
I dumped both the CBM 1520 Plotter ROM versions
(-01 and -03).
The 1520 is the little 4-pen Alps mechanism, isn't it?
Are these ROM images avaialbe for download anywhere?
