1. Encore Computer Corporation, of course.

3. Umax is 4.x BSD, where x approaches 3 as the year approaches 2000. :-)

2. The question really is "what type CPUs does it have."
Encores come with some number of identical processors in
each box, usually ns32k's, usually from 2 to 20 of them.
To find out what you really have, cc and run the following
program on your local encore:

---------------------Clip 'n' compile--------------

/* sm.c -- demo program for sysadmin(3). */
/* Do "man 3 sysadmin" to get the scoop on this function. */

#include <sys/sysadmin.h>

main()
{
    int arg1;
	
    arg1 = PT_TMEM; /* Return the amount of total (pageable) memory in pages.*/
    do_sm(arg1);

    arg1 = PT_PGSIZE; /*  Return the size of a page in bytes. */
    do_sm(arg1);
}

do_sm(arg1)
int arg1;
{
    int cmd;
    cmd = SADMIN_NUMCPUS;

    printf( "There are %d ", sysadmin(cmd, arg1) );

    cmd = SADMIN_CPUTYPE;
    switch(sysadmin(cmd, arg1)){
	case CPUTYPE_DPC:
	    printf("DPC ");
	    break;
	case CPUTYPE_APC:
	    printf("APC ");
	    break;
	default:
	    printf("unknown-type ");
	    break;
    }
    printf("processors,\nwith ");

    cmd = SADMIN_FPUTYPE;
    switch(sysadmin(cmd, arg1)){
	case FPUTYPE_NS:
	    printf("an NS32081 ");
	    break;
	case FPUTYPE_CONE:
	    printf("a CONE ");
	    break;
	default:
	    printf("an unknown-type ");
	    break;
    }
    printf("floating-point coprocessor.\n");

    cmd = SADMIN_PAGE_TUNE;
    switch(arg1){
	case PT_TMEM:
	    printf("The amount of total (pageable) memory in pages is %d.\n",
		    sysadmin(cmd, arg1) );
	    break;
	case PT_PGSIZE:
	    printf("The size of a page, in bytes, is %d.\n",
		    sysadmin(cmd, arg1) );
	    break;
	default:
	    break;
    }
}

#if 0
(Just in case.)

Typical output looks like this:

    There are 6 APC processors,
    with an NS32081 floating-point coprocessor.
    The amount of total (pageable) memory in pages is 8433.
    There are 6 APC processors,
    with an NS32081 floating-point coprocessor.
    The size of a page, in bytes, is 4096.

"APC" is the version of the processor card.  There are two CPU's
per card, so this says I've got 3 APC cards.  The rest is self-
explanatory.

Yes, you Encoreites are saying "hey, what about XPC's?"
well, check your manual pages and see if CPUTYPE_XPC is
documented.  I don't have an account on any XPC machines,
just some APCs and DPCs.

No, the program's not beautifully elegant, being redundant in its
output, but I wrote it simply to exercise susadmin(3), and it's
too easy just to post it rather than cleaning it up...
