IEE 3785R dual 14 segment LED pinout

I traced out my IEE 3785R dual 14 segment red LED module.
There are 4 common cathodes, dividing the character diagonally
so it's electrically 4: 7 segment displays instead of 2: 14 segment displays (not counting decimal point).

______A______
|F \H |I /J |B
__G1__ __G2__
|E /M |L \K |C
______D______   .dp (decimal point)

IEE 3785 pinout
common cathode:	pin 1	pin 3	pin 4	pin 6	pin 9	pin 12	pin 14	pin 17	pin 18
pin 5 left char	G2	K	C	dp	-	D	B	L	J
pin 15 left char	G1	M	E	-	-	A	F	I	H
pin 10 right char	G2	K	C	-	dp	D	B	L	J
pin 8 right char	G1	M	E	-	-	A	F	I	H

The segments are named as per this data sheet for teeny 16 segment LED modules
I guess I can connect pin 6 to 9 to use an 8x8 controller to get both decimal points.

It's also Kingbright part number PDA54-12GWA

blueroomelectronics notes "Treat them like a 4 digit common cathode display"
so an 8x8 matrix driver chip (such as the Maxim 7219) will drive 4 characters with decimal points.

justDIY notes that IEE [the display company] was purchased by Fairchild,
who dumped their opto division and removed all data sheets from their website.

Here's a full ASCII font (upper and lowercase) that I designed for old HDSP-6508 sixteen-segment "starburst" displays.
