Unfortunately, OS4.0 format is broken, and will not handle the Wren V
94181-702 (and probably not the Wren V 94186-383H as well) even if you had
the correct format.dat entry. The format supplied with 4.0.1 _can_ handle
the Wren V 94181-702 (and therefore probably the 94186-383H as well). But,
in case you want to try anyhow, here's the Wren V 94186-383H entry from
the 4.0.1 format.dat:

disk_type = "CDC Wren V 94186-383H" \
	: ctlr = MD21 \
	: ncyl = 1218 : acyl = 2 : pcyl = 1224 : nhead = 15 : nsect = 35 \
	: rpm = 3600 : bpt = 20833

Good luck.
