..> UNIX in ROM

Several people have expressed worry about the maintainability,
or vulnerability to bugs, of UNIX in ROM.

The appropriate way to use ROM is as a library, with, perhaps,
minimal glue code. All calls to ROM routines should be via a
dispatch table which ROM loads into RAM. The dispatch table can
then be patched, perhaps to pint to new RAM code for bug fixes.

    aglew@gswd-vms.gould.com    - if you don't
    aglew@gswd-vms.arpa 	- if you use DoD hosttable
    aglew%mycroft@gswd-vms.arpa - domains are supposed to make things easier?
