[Simh] PDP10: KS10 console lights?

[Lars Brinkhoff]

Hello,

There is a USB device called the Panda Display.  Its purpose is to allow
PDP-10 simulators to display internal state using LEDs, much like a
front panel.  I have patched Richard Cornwell's KA10 simulator to make
the DATA PI, instruction display on the LEDs.

I have checked the KS10 instruction set.  It doesn't have a DATAO PI,
instruction.  However that particular opcode isn't in used, so it's just
a UUO.  This is also the case for ITS microcode.  Before I start working
on anything, I'd like to ask if it would be OK to repurpose this opcode
for its traditional use?
