It's a disease that has no cure..........WTF did he do now???

Years ago, decades ago, actually ... I was race director for the local motorcycle road-racing club. Terrible racer ... I always came in second to last ... but excellent administrator. One year we had a new track built on an old airfield. We set up the track using firehose stuffed with pea gravel. The first time we set it up it took something like 6 hours ... it was horrible. I went home6u and used 2D CAD skills I had learned in a college class on, was it Mini-APT? I wrote out a bunch of pages of instructions in the spirit of the CAD software. The next time we set up the track in an hour. It was brilliant!

Also, it gives me pleasure to read "FORTRAN" in a post here. I worked on a DEC PDP11/34 with a 2.5MB RK05 disk pack. I loved that machine.

Old people - RT-11, RSX-11, or RSTS/E?

When the VAX and VMS arrived in 1978 we graduated to hog heaven - 2GB virtual address space and a row of 178MB RP06 top loading "Maytags".

Congratulations, that's a fun purchase.

As a note, ground water content throughout different seasons can affect the grounding and therefore the arc, so you might "tweak" your setup throughout the year for consistent results. Also watch your consumables, they go from "kind of crappy cut" to "Boom!" quickly, so when draft angle starts becoming noticeable check your consumables for wear. Your software might have "start" and other counters that keep track of the number of pierces, cut duration, and other metrics for each tip...good stuff. And dry, constant pressure air is really important for equipment lifespan.

Personally I like FreeCAD, the tutorials are awesome and I find the software easy to use. I save often, with names like:
Bucket-Brace-2024_08_07-01a
Bucket-Brace-2024_08_07-01b
and when making a major revision:
Bucket-Brace-2024_08_07-02a

We break the 3-D assembly models into flat 2-D part templates and path those...not to say anything I've mentioned is the "right" or "best" thing for anyone else, just tossing a few ideas out there hoping they are of use.

We're starting to hijack this thread ... but to answer your question .... RT-11. In business school ten years later we had a VAX ... VAX/VMS was wonderful.

One of my biggest successes was modifying the RT-11 hard disk driver, which was in assembly language, to make two RK05 disks look like one. That got me 5MB of storage, which is what we needed to store the EKG data we were recording.

Those machines were works of art. I was so sad when DEC went out of business.

Hijack is the name of the game in Off Topic.

Lots of people were sad. DEC should never have pissed Dave Cutler off. He made Bill Gates and Paul Allen very happy.

Oh yeah, I forgot this was Off Topic. heh heh.

Thanks for the little bit of history. I looked up Dave Cutler ... I wasn't aware of the through-line from DEC into Windows NT ... Azure ... XBox. Interesting.

Geeks have a strange sense of humor:

WNT = VMS+1 and the kernel sits on top of the hardware abstraction layer (HAL). Think anybody was reading Arthur Clarke?

And of course HAL = IBM - 0111

re: TRS-80, have 2 Model IIIs in basement, ran business off one for decade+, Played with BASIC-11 on the PDP-11/34,usually in Assembler. Still have the nameplate for the PDP-5 here, somewhere,though the core modules(yeah, REAL mag core) are long gone. Gone through the alphabet of computers and languages, yeesh, 5+ decades worth or is that Wurth ?
Friend didn't like the lack of precision of 'wood carving' CNC, so he made his own. Can do 5by9 FEET of 'artwork', also cut all the code to run his machine,super fast, ultra accurate and repeatable,only takes seconds to compute size of artwork .

You know what's cool here is the interesting mix of people we have on the forum, brought together because we own a certain brand of tractor.
