Here are Disch's original notes:

It is believed that this mapper does not suffer from bus conflicts.
$8000-FFFF: [MM.. PPPP]
P = PRG Reg (16k @ $C000)
M = Mirroring:
%00 = 1ScA
%01 = Horz
%10 = Vert
%11 = 1ScB
PRG Setup:
--------------------------
$8000 $A000 $C000 $E000
+---------------+---------------+
| { -1} | $8000 |
+---------------+---------------+
Mapper 180 is basically this mapper without mirroring control. (But the fixed bank is 0, not last)
