Hi all,
	I've just answered my own question. Reading thru the 11/20
processor handbook, I see the section on the extended arithmetic element,
KE11-A, which is ``an option to perform multiplication, division,
multiple position shifts and normalization significantly faster than
software routines''.

I also see that unit 1 lives at 777300 - 777316, and the date a.out
executable does this:


230:    TRAP 15			time syscall
232:    MOV #177770,@#177314
240:    MOV #47432,@#177300
246:    ADD #5,@#177304
254:    MOV #7,@#177300
262:    MOV @#177302,@#177304
270:    MOV #5,@#177306
276:    ADD #40622,@#177304
304:    MOV @#177304,320
   . . .

So it looks like I need to add KE11-A support to my emulator :-)

Cheers,
	Warren
