Subject: [Emc-developers] A halmeter enhancement Greetings all;I never made it
to the garage today as I had a bad time with leg cramps in the night so didn't
get a lot of good sleep last night. They ached all day.How hard would it be to
cause the text background of the halmeter to switch colors when its in the
true/false mode for a logic signal?You could use halshow which has LEDs for
booleans. Although apparently it is not as fast as halmeter

When piddling with this G-704's spindle encoder, changing its index from an
opto-interrupter to an ATS-667, the halmeter on the monitor screen is too far
away to read the true/false text. But I could see a color change from several
feet farther away. I know which of the wires is ground and which is the 5 volt
supply, but there was originally the A/B/Z wires and I need to find the Z
wire.I threw that opto stuff together on two pieces of perfboard, one holding
the slot gizmo's and one holding a quad cmos buffer to give me rail to rail
outputs quite a few years ago without documenting it, a bad habit of mine.?? a
possible halmeter enhancement patch ??Thanks all.Cheers, Gene Heskett-- "There
