Hmm, I don't know about anyone keeping them, but in the 2.2 release notes,
which I have a copy of, says:

	In order to patch the system-wide ulimit value, use the following
	syntax: "patch /system5 ulpatch nnn" where nnn is the new ulimit
	value in decimal.  The ulimit value controls the maximum writable
	file size.  The maximum value for the system-wide variable is about
	32K blocks, resulting in a maximum file size of about 16MB.

The units are 512-byte blocks, so the default of 2400 is exactly big
enough to copy a 1.2M floppy.  The value in the kernel is the value
inherited by init, which then passes it along to all its progeny.
