Finally powered up the 7C81. No issues at all.
A couple of questions based on the results shown below.
1) Why is the direction IN for pins named "out", and OUT for pins named "in" halcmd: show pin?
2) I ran pncconf and was going to setup for another card and then edit files as described here . But I couldn't figure out the default configuration loaded into my 7C81. See the end of this post. What am I not understanding?
Thanks for your help.

$ mesaflash --device 7c81 --addr /dev/spidev0.0 --spi --readhmid --verbose
$halrun
halcmd: loadrt hostmot2
Note: Using POSIX realtime
hm2: loading Mesa HostMot2 driver version 0.15
halcmd: loadrt hm2_rpspihalcmd: show pin
halcmd: getp hm2_7c81.0.gpio.001.out
FALSE
halcmd: setp hm2_7c81.0.gpio.001.out 1
halcmd: getp hm2_7c81.0.gpio.001.out
TRUE
Did the following for pncconf with 7C81 files downloaded from store.mesanet.comsudo mkdir /lib/firmware/hm2sudo cp -p mesa_software/7c81/configs/hostmot2/* /lib/firmware/hm2/
To try and figure out the default configuration loaded into the card I ran:
$ mesaflash --device 7c81 --addr /dev/spidev0.0 --spi --verbose --readhmid | grep "There are "
Then ran this, but found no match.
grep "There are " mesa_software/7c81/configs/hostmot2/7c81_*.pin

1. A physical input pin is an output in HAL because its HAL pin provides a value
A physical output pin is an input in HAL because its HAL pin accepts a value
2: Default 7C81 firmware is 5ABOBx3.
Note that for pncconf you can just use a similar parallel port type config to get close,
since things like Stepgens and PWMgens are selected by index rather than pin number,
so as long as you choose the actual firmware in the 7C81 to match your breakout,
most things will just work. The exception is GPIO setup which will likely require hand editing
of the hal file.

I'll jump on with a question of my own -
I'm assuming the 7c81 uses SPI0 to communicate; is it possible to use SPI1 instead?

Please do not change the subject when replying, it makes it very hard to find the topic with two or more tittles .
Thank you.

Thank you Peter.
I had some time to work on this again today.
--readhmid reports that what is programed in the 7C81 board has "1 of QCount" and "10 of StepGen", while the 5ABOBx3 has "3 of QCount" and "12 of StepGen". You obviously know what's programmed in there, but I'm curious why there is a difference between the board query and the pin file?
I ran pncconf. Made the first screen settings what you suggest in another thread.
All I changed on the "Base Information" page was the machine name.
I'm using Axis. No clue what what to change under the "General GUI Defaults", so changed nothing.
Did nothing with the "Virtual Control Panel" or "External Controls" pages.
On the "Mesa Card 0" page I looked at "Firmware:" listed under every "Board Name:" available. None of these boards have 5ABOB3x3 as a firmware option.
I wasn't really sure what to do at this point so I went with 5i25-internal data board, and the G540x2 firmware. I then set arbitrary X, Y, and Z stepgens so I could proceed to generate files.
There were a few other screens asking very detailed information which I'll have to figure out, but didn't worry about it for now. I was actually a bit surprised, given the amount of data that all of the pncconf pages ask for, that the ini and hal files don't have more lines in them. (and thankful)
Easy enough to change 5i25 to 7C81, but this can't be correct since the board is programed with a 5ABOBx3, and I used G540X2. So one can't use anything but a G540X2 with a 7C81?
I appreciate that LinuxCNC is a large and complex software suite which enables it to support a myriad of system combinations. But wow, it sure is tough for a beginner to set up something that is probably relatively simple compared to most.
Thanks again for the help.

I suspect the pin file is older and perhaps doesn't fit in the 7C81
You can use a similar pncconf firmware configuration (G540 is quite close to 5ABOB)
to get very close to a working hal/ini file set.
This is because things like stepgens or encoders are addressed by channel number, not pin
so the actual pin numbers for these are "dont-care"
The only exception is that available GPIO pins may not match so you may need to
re-assign some GPIO numbers in the hal file for things like spindle-on etc

Hi Peter,
Where could I get the 5ABOB pin file that matches what is programmed into the the 7C81? The pin file I have is downloaded from www.mesanet.com/software/parallel/7c81.zip
Thanks,
Gene

You make it with mesaflash --readhmid (redirecting the output to a .pin file)
if you want 5ABOB pins you include --dbname1 5abob
if you want 5ABOB pins you include --dbname1 5abob
