Been saving up to buy a used Mach1. Should be there by next Wednesday. If any of you new Mach2 owners have a Mach 1 you are willing to sell please contact me via private message/email. If the moderator feels this post is inappropriate please remove.
Thank you.

Re: Slide Rules and Slipsticks - in the 1960's B.C. - i.e. (Before Computers)
Joe Zeglinski
Maybe, I can somewhat top that, Don.
First year engineering, Fortran punched card
programs, on the big fish-bowl machine – an awe inspiring IBM-7094, long
before the IBM-360, and which was the original IBM-7090 upgraded
with something new - a Floating Point Processor.
That was the death knell for the desktop NCR Tabulators. The UofT had the
fortune of getting the second IBM-7094 in production, after NASA got
theirs for Project Mercury. The latter’s introduction is portrayed in the
recent movie, “Computing Figures”, which brought back wondrous memories for
me.
But I preferred using the undergrad machine, an IBM-1620
with a coffin-sized floating point processor, we hung over it to get
ourselves warmed up on a cold winters morning, Working for the eelier mentioned
prof, even got special permission to actually run it after midnight – my
first PC, sort of. Loved to turn off the lab room lights, and enjoy all the Neon
Hex-code indicators and control panel switch’s lights flash like a laser show.
Wish I had taken a picture. No PC today compares to that thrill and amazing
sight, perhaps only beat by the IBM-7094 and IBM-360 light show when
running diagnostics.
Last thing I did with one of my dozen or so
basement Honeywell Minicomputers, was to play an originally PDP-8
programmed, Christmas Carol, from the RFI noise generated by the
mini’s control panel (specifically) incandescent bulb, (Arithmetic
Overflow flip-flop Indicator), flickering on & off by program as a
portable radio tuned to any off-AM-station frequency , crackled melodically,
even 10 feet away, in unison to the carol. Computing Security wasn’t a
concept in those early days.
“Halcion Days” ... of computing, when computers
were new and lots more fun than debug work, after I taught myself
computing, before Computer Science came along,
Thanks for bringing back all the shared memories,
guys. Now back to my bug-free Pickett – wonder why we called its
sliding indicator window a “Cursor”, instead of a “Mouse”, since it really
worked the same way :-)

I will say, however, that I did not find it exactly a chick magnet. I went to UVa, and it was the very early days of women in the undergraduate program, so they were few enough, but even fewer in the Engineering school. Even so, I saw no indication the slide rule had any attractive force.
Of course, being in the Engineer school the women there had slide rules as well, so that may have affected any behavioral observations.

Re: Slide Rules and Slipsticks - in the 1960's B.C. - i.e. (Before Computers)
Yes Joe anyone under 50 (probably 60) has no idea what were talking about. Think about the things that were built ie Hoover Dam Titanic etc that were all designed using hand calculations and slide rules. What most people don't realize about slide rules was one had to have a good idea what the final answer was while doing the calcs in order to carry the decimal point through the calculation process.

I forgot that you have a side-by-side setup. Those are a bear to balance. As I recall, it took me nearly an hour to get my side-by-side solar setup properly balanced in all directions and axis the first time. And your scopes are so much larger and heavier.
But at least the meter is helping.
All that said, if I could justify the cost, I’d sure like to get the AP gear-release retrofit kit their “new” mounts have.

Opposed to the cost of a new mount and of course the biggest advantage... a very accurate balance which would alleviate an aweful lot of headaches!...Ive been asking for several years about this possible mod.... sign me up as well.... pleeeeaaassseee!...lol

Re: Quick Release Gearbox Modification for Older AP1600
Jack and all,
The swap out is not an easy one, which is one of the reasons that we have not offered it yet. Yes, many of the components can be reused (motor assembly, worm gear, spur gears), which will reduce the cost. However, it is likely that the mounts will need to return here in order to swap out the components and to ensure accurate assembly.

Jack,
I forgot that you have a side-by-side setup. Those are a bear to balance. As I recall, it took me nearly an hour to get my side-by-side solar setup properly balanced in all directions and axis the first time. And your scopes are so much larger and heavier.
But at least the meter is helping.
All that said, if I could justify the cost, I’d sure like to get the AP gear-release retrofit kit their “new” mounts have.

Re: Quick Release Gearbox Modification for Older AP1600
Roland, will this be a simple swap out for current AP1600 owners. I assume that the existing worm gear would be retained and moved to the new housing for the quick release system. Any estimate on price and is there a waiting list for this retrofit?
