   The ICM project is pretty dead last I heard.  National kind of left
it to hang out and dry (Why I am not sure).  In my case it is a pretty
good reason not to consider using National stuff at work.

I am trying to donate, to a charitable organization my ICM w 100 MB
disk. Are you a charitable organization and can you prove it to the IRS?

I didn't know they made a Ethernet controller - any software?

At one time I heard mention of a gate array which was supposed to make
the Minibus wonderful.  Never actually heard of silicon though.

UofT will still supply a BSD 4.2 port as I found out a couple months
ago after about 2 years of trying.  The person who wrote it is no
longer at UofT but UofT is still willing to sell it for about $400.
Since it is a pretty stable product (as several people on the net have
said) buying it under these conditions would probably be OK (If you
want to sink more money into an ICM?)  I can't find the letter at the
moment but I can post the phone and/or mailing address when I clean my
desk off. :-)

I have ported GNU EMACS about 18.49 to the (very) raw SYS V.2.2
distribution from National.  I have rev B of the software which needed
the following hacks.

in m-ns16000.h:
#define SHORT_CAST_UG
#define NO_REMAP

and the most serious problem in malloc.c, get_lim_data(), was that
ulimit(3,0)  is brain dead (on my version) and I replaced it by 
        while (srk(128 * 1024) > 0)
          lim_data = sbrk(0);

My only comment was that SDB was at least up to debugging GNU EMACS
and introduced me to real symbolic debuggers.

Good luck and let me know if you are a non-profit organization.  

(P.S. My opinion of the ICM is that the CPU is fine (about a VAX 780
MIP) but the disk controller stinks.  Also I have gotten used to SUN 3
performance and SUNOS.  You can purchase later releases of the
software from National (rev H, I think), and while they recommend
hardware modifications, they probably aren't needed.)
