Success!
Thank you all for your help.
I made a bash script: M133,
#!/bin/bash
# file to clear messages
halcmd setp classicladder.0.in-13 True
sleep .01s
halcmd setp classicladder.0.in-13 False
exit 0
In classicladder it is in parallel with a push button added to the GUI
,they in turn trigger a one shot which tells hal :
net clear-DISPLAY classicladder.0.out-07 =
axisui.notifications-clear-info

I guess you could say I did my revamp on the cheap.
I simply replaced the motherboard with a parallel interface card .
Had some linsteppers that I wasn't using .After removing the power
transistors wired them into the existing stepper drivers and motors.
So I could use step and direction control.
Using existing spindle and turret boards.
I get the encoder signal from the spindle board .I don't know if any
current limiting is done there.Its the same signal that was going into
the motherboard.
I have a P I loop with wpm (inverted) output and that pot replacer low
pass filter circuit for spindle speed control.
Now that everything is up and running and what a jewel it is, I want to
add home switches to the axis and the turret.
My max speed is 27 ipm ,any faster and the motors sound bad.
The spindle at speed (set at 10%) blinks about every two seconds .
Hopefully I can fix this by tuning.
One of the first jobs I did, was making new tie rods which hold on the
turret motor they have a 2.5 x.45 mm thread on each end .
It's the little engine lathe that could.
Thanks again to everyone for the help. Jim

Thank you Sebastion,
This is for my new to me EMCO compact 5 cnc lathe retrofit.
Hey! Im currently doing three of these! I have one machine up and running
w/ Mesa boards, new steppers+drivers, D525MW, and an ELO touchscreen. Only
thing I reused is the power supply (though i think I may reuse the spindle
drive on the next one.) I've figured out the spindle encoder feedback so
should have that fixed and up and running this weekend (note: there are NO
current limiting resistors for the diodes in the potted sensor block;))
