Syntax for Bridgeport Boss 6 canned cycle?

Can anyone help me with the correct syntax for drilling a bolt hole
pattern on this old Boss 6 control?

I have tried:
N100 G81 X1.0 Y1.0 Z0.2 H8 A0 R1.0 F150
which doesn't seem to work.

X,Y is center of pattern, Z is depth,
H is # holes, A is starting angle, and R is radius

The control does not understand H (# of holes).

Anyone that can enlighten me to the correct syntax would be greatly
appreciated.

Thanks,
Tim M
