I've got a few RD5x disks to format with an old VS2K, disks which have
been formatted on a PC since they were last used in a DEC system.  In
other words, I have to go through the whole geometry, staggering, bad
block handling and so forth with the formatter.  I've got most of the
parameters figured out, but I need to know what the proper media IDs
are for the various disks.  They're supposed to be rather large
numbers that DEC disk drivers read from the disk to discover what type
of disk it is.  For instance, I read somewhere that for the RD51 it is
supposed to be 627327027.

Anyone have a list of these?  Source code to read where they're used?
Any other relevant information on the VS2K TEST 70 formatter, like the
best parameters to use for various RD series disks?
