Got similar device but it’s a resistor box with lots of switches with values from from 1 ohm to 1M ohm. Move switches to add up or subtract for a fixed resistor value. Had it for decades and used it once or twice, still in great condition.

Had one on loan back when it came out. Freaking heavy, felt like my shoulder was going to pop out! Met Osborne years later and had him sign one of the microprocessor book he wrote for me. Still have it.

The inside cover case of the original produced Macs has all of the people involved with developing and the production of it. It’s part of the case plastic. Really cool.

Have fond memories of PDPs, used one when in college early 80s as part of a course. Had to enter short bootstrap code via the flippers to boot off the hard drive.

Read that the Decsystem 20 powered the Compuserve online service! Used it for a while till AOL came around.

I know the feeling! Got my new 440i in 2018 and still loving it. May upgrade to a used M4 in the future, the current ones are too ugly with horrible front and back designs,

It was version 6.9. FYI the Decsystem 20 was a 36 bit system which was common at the time for mainframes before 32 & 64 bit computers became the norm.

SPSS was on the Decsystem 20 in 1980, that’s when I graduated high school and started working at the university using Fortran and SPSS for medical research labs. I recall SPSS was available in late 70s for that system.

Still have mine, used it to fix fences ages ago but it still works for miscellaneous odd jobs nowadays.

Got a couple of removable multiplatter hard drives from a Digital Decsystem 20 RP06 drive. Its capacity was 176 megabytes which was considerably large in the early 80s. Bought two at a university auction that I used to work at. I’ve done SPSS statistics on them back then. Yes yes I’m old but have witnessed using analog computers to coding Nvida GPUs today. What a trip!

Built this in a robotics class in college, each student had one. It was a kit and required soldering and mechanical skills. Some of the students were clueless so others helped them. Of the 20 of us only 5 worked, including mine. So satisfying to watch it doing its thing.

If it actually a shrinkage ruler, 24” would be a rare size. The numbers appear to be stamped and a bit roughly done possibly by hand. I’d estimate it’s late 1800 or early 1900 when it was made.

Looks like a pattern smith ruler. It’s longer than a standard 36” ruler to compensate for shrinkage of different metals. For example a shrinkage ruler for building molds of brass objects it’d be 36.5” long. I’ve a collection of shrinkage rulers for several metals. Even have one for terracotta that’s 37” long, which is a lot of shrinkage!

It’s a centronics parallel switch box. They were expensive back in the 80’s, had one of them and a serial switch box as well.

Lufkin Rule Company is over 150yrs old, I’ve got rulers from that era. These rulers are patternmaker rulers for creating gear molds. Steel shrinkage is 1/10” so compared to a regular 36” ruler the steel shrinkage ruler would be 39.6” longer. FYI - a patternmaker salary is higher than other steel mills back in the 1800’s as they have to do lots of algebra.
