Ok.

Address map says "Zalon". That's the GSC front end for NCR c720 board.
I think from ioscan.B132L its:
ext_bus     1  8/12  c720 CLAIMED     INTERFACE    GSC Fast/Wide SCSI Interface

iodc data for 8/12 device is:
	3 192 0 132 0 0 137 128 153 0 1 0 197 233 0 2

You'll have to figure out if that matches...I'm not up to it right now.
C720 driver normally says "Built-in" if some PDC call says it's a built-in.
So I don't really know what to make of it.

I would think both.
But I was wrong about dino exporting it's RS-232 on this box.
The B180 does export Dino's RS-232 from 8/0/63.
But I was right in that Lasi only exports one of them.

Again, based on the HPA, I'd say 11 and 12 are the PS/2 ports off Lasi.
15 is most likely off the WAX chip (EISA bus adapter.)
I don't know if B132L has EISA slots (haven't looked inside one in
a long time), but HP-UX reports "EISA Bus Adapter" at 8/20/5.
So I would assume it does.
Note that the B180 does NOT. And thus doubt the A180 would either.
