Re: Slide Rules and Slipsticks - in the 1960's B.C. - i.e. (Before Computers)
My high school days were spent on an IBM 1440 (first 2 years) and a UNIVAC 1106 my senior year. Mostly FORTRAN then COBOL, ALGOL and assembly on the UNIVAC.

Re: APCC shows Altitude at 0 in Park 3
Hi Ray, I have tried that no luck. Trying reboot and restart the CP5 right now...
nope. This did happen some time ago and you had a solution if I recall but can’t remember!

Re: APCC shows Altitude at 0 in Park 3
Hi Wayne,
That might happen if there happened to be a communications issue getting the latitude. Try restarting APCC.

APCC shows Altitude at 0 in Park 3
Altitude at park 3 should be 47 degrees. Site is correct. This happened before, not sure what the problem is.

Wow! Awesome Barry. How heavy is it? Mine is a Hughes-Owens Bamboo with glass window in the slide. It is in as good a shape as when I bought it in 1969.

Congrats Barry,

Yes – that is a 6-foot slide rule on the wall. Couldn’t resist buying it years ago at a garage sale. These used to hang on the blackboard in my high school chemistry class so they could teach us

Re: How to Re-grease a Mach1 with Auto-Adjust Motor Boxes?
MoS2 is very bad for brass or bronze worm gears. The S2 (sulfur) corrodes these metals. Lithium is usually too thin. Try a super lube type grease without sulfur.

I did have my scope well-balanced in both axis. I guided it for a short while as a test for a 5 min sub (image below) then turned it off and went unguided and noticed the stars were of identical

Re: Mach2 - Elongated stars
Please post a screen shot of the guider graph with corrections showing, and all other details. From that I can tell you if there is anything going on with the mount.
