Whoever "sysadm" is, he/she sent me an extensive FAQ on NVRAM's in
Sun systems which includes instructions for burning new EPROM's.
If anyone wants it, I'll send it along.
Mark, John McWilliams, and joem sent the part number, 520-2749.
Mark also told me:

The change-sun-hostid-1.4.8.tar.gz file contains instructions for
using the SLC FORTH interpretor (that's what's running when you
set the ">" prompt) to program a new NVRAM.
We called Mauser, but they're back ordered on these chips, with
at least a month delay to get them.
Sun Service would not give me a price for creating a new NVRAM
chip unless I agreed to pay up front! This sort of
reminds me of the car salesman who won't tell you the price of
a car unless you promise to buy it. SunExpress does not carry
parts this old.
One Sun repair depot gave me a price of $250 for replacing the
NVRAM, but it requires sending in the system board.
