Pretty much all manual typewriters use 1/2" (12.7mm) wide ribbon which is most of what you're probably going to find in the marketplace.

The thing that changes from machine to machine is is the potentially proprietary spools and those are usually specific to how the ribbion auto switch is effectuated. Most ribbon comes with small grommets about 10-12 inches from the ends as many machines need this to trigger the switch over. If the plastic spools you purchase don't work with your particular machine you simply spend a minute or two to hand wind it onto your existing original (metal) spools and go from there.

There are lots of videos on YouTube showing how to hand wind ribbon onto a machine. Sarah has a pretty reasonable one: https://www.youtube.com/watch?v=up412FjTEkw

Even Tom Hanks has a ribbon changing video... https://www.youtube.com/watch?v=GBbsNKaVAB0

Incidentally, if your seller specifies them, the Underwoods take Group 9 (GR9) spools. Likely not helpful or illustrative for you, but certainly interesting from a historical perspective, Ted Munk has a catalog of Typewriter Ribbon varieties Offered by Underwood in 1956: https://munk.org/typecast/2020/08/23/typewriter-ribbon-varieties-offered-by-underwood-in-1956/

A Note on the Cargo Cult of Zettelkasten

Modern cargo cults can be seen in many technology and productivity spaces where people are pulled in by exaggerated (or sometimes even real claims) of productivity or the general "magic" of a technology or method.

An example is Niklas Luhmann's use of his zettelkasten which has created a cargo cult of zettelkasten aspirants and users who read one or more of the short one page blog posts about his unreasonable productivity and try to mimic it without understanding the system, how it works, or how to make it work for them. They often spend several months collecting notes, and following the motions, but don't realize the promised gains and may eventually give up, sometimes in shame (or as so-called "rubbish men") while watching others still touting its use.

To prevent one's indoctrination into the zettelkasten cult, I'll make a few recommendations:

Distance yourself from the one or two page blog posts or the breathless YouTube delineations. Ask yourself very pointedly: what you hope to get out of such a process? What's your goal? Does that goal align with others' prior uses and their outcomes?

Be careful of the productivity gurus who are selling expensive courses and whose focus may not necessarily be on your particular goals. Some are selling very pointed courses, which is good, while others are selling products which may be so broad that they'll be sure to have some success stories, but their hodge-podge mixture of methods won't suit your particular purpose, or worse, you'll have to experiment with pieces of their courses to discover what may suit your modes of working and hope they'll suffice in the long run. Some are selling other productivity solutions for task management like getting things done (GTD) or bullet journals, which can be a whole other cargo cults in and of themselves. Don't conflate these![^1] The only thing worse than being in a cargo cult is being in multiple at the same time.

If you go the digital route, be extremely wary of shiny object syndrome. Everyone has a favorite tool and will advocate that it's the one you should be using. (Often their method of use will dictate how much they love it potentially over and above the affordances of the tool itself.) All of these tools can be endlessly configured, tweaked, or extended with plugins or third party services. Everyone wants to show you their workflow and set up, lots of which is based on large amounts of work and experimentation. Ignore 99.999% of this. Most tools are converging to a similar feature set, so pick a reasonable one that seems like it'll be around in 5 years (and which has export, just in case). Try out the very basic features for several months before you change anything. Don't add endless plugins and widgets. You're ultimately using a digital tool to recreate the functionality of index cards, a pencil, and a box. How complicated should this really be? Do you need to spend hundreds of hours tweaking your system to save yourself a few minutes a year? Be aware that far too many people touting the system and marketers talking about the tools are missing several thousands of years of uses of some of these basic literacy-based technologies. Don't join their island cult, but instead figure out how the visiting culture has been doing this for ages.[^2] Recall Will Hunting's admonition against cargo cults in education: “You wasted $150,000 on an education you coulda got for $1.50 in late fees at the public library.”[^3]

Most people ultimately realize that the output of their own thinking is only as good as the inputs they're consuming. Leverage this from the moment you begin and ignore the short bite-sized advice for longer form or older advice from those with experience. You're much more likely to get more long term value out of reading Umberto Eco or Mortimer J. Adler & Charles van Doren[^4] than you are an equivalent amount of time reading blog posts, watching YouTube videos, or trolling social media like Reddit and Twitter.

Realize that reaching your goal is going to take honest-to-goodness actual work, though there is potential for fun. No matter how shiny or optimized your system, you've still got to do the daily work of reading, watching, listening and using it to create anything. Focus on this daily work and don't get sidetracked by the minutiae of trying to shave off just a few more seconds.[^5] In short, don't get caught up in the "productivity porn" of it all. Even the high priest at whose altar they worship once wrote on a slip he filed:

"A ghost in the note card index? Spectators visit [my office to see my notes] and they get to see everything and nothing all at once. Ultimately, like having watched a porn movie, their disappointment is correspondingly high." —Niklas Luhmann. <small>“Geist im Kasten?” ZKII 9/8,3. Niklas Luhmann-Archiv.

This sounds a bit like the idea of reverse outlines I'd heard about recently but haven't fully looked into yet.

!- Michael Hudson : reverse privatization and wipe out debt - returning the public infrastructure sold off to companies after 1980 back to the public to get rid of monopolies who gouge the public - cancel all debt so that the savings of the 1% cannot continue compound growth trajectory

Disappearing enso, writing down the emptiness.

I quite like the idea of intertexts, which have the feeling of annotating one's own published work with the annotations of others. A sort of reverse annotation. Newspapers and magazines often feature pull quotes to draw in the reader, but why not have them as additional voices annotating one's stories or arguments.

This could certainly be done without repeating the quote twice within the piece.

Many people treat their blogging practice as an experimental thought space. They try out new ideas, explore a small space, attempt to come to understanding, connect new ideas to their existing ideas.

Ton Zylstra coins/uses the phrase "metablogging" to think about his blogging practice as an evolving thought space.

How can we better distill down these sorts of longer ideas and use them to create more collisions between ideas to create new an innovative ideas? What forms might this take?

The personal zettelkasten is a more concentrated form of this and blogging is certainly within the space as are the somewhat more nascent digital gardens. What would some intermediary "idea crucible" between these forms look like in public that has a simple but compelling interface. How much storytelling and contextualization is needed or not needed to make such points?

Is there a better space for progressive summarization here so that an idea can be more fully laid out and explored? Then once the actual structure is built, the scaffolding can be pulled down and only the idea remains.

Reminiscences of scaffolding can be helpful for creating context.

Consider the pyramids of Giza and the need to reverse engineer how they were built. Once the scaffolding has been taken down and history forgets the methods, it's not always obvious what the original context for objects were, how they were made, what they were used for. Progressive summarization may potentially fall prey to these effects as well.

How might we create a "contextual medium" which is more permanently attached to ideas or objects to help prevent context collapse?

How would this be applied in reverse to better understand sites like Stonehenge or the hundreds of other stone circles, wood circles, and standing stones we see throughout history.

Variable Reverse Repo-rate

This is based on the fundamental misconception of the value that the commons adds to society.

Just confirming what I believed to be the case. I couldn't remember whether I'd read results of this specific sort, so I figured I should look it up. Chronic KOR agonism appears to be an ideal opioid hack.

Fascinating and useful stuff. This is close to what I was expecting. Though, I was expecting chronic exposure to upregulate dopamine beyond baseline. If I'm understanding this correctly, it was upregulated in the sense that it enhanced the dopaminergic effects of cocaine. I've not yet read the full study.

Looks promising. It's odd that theophylline had a lesser effect.

It's not clear if this has relevance to the subjective effects. I'm starting to think that I won't get an answer anytime soon.

This is analgesia, so is not necessarily relevant for my purposes. Nonetheless, there implies some relevance of cGMP, but the direction isn't yet clear.

If they mean what I think they mean, then this implies that chronic KOR is useful. I'll need to check citation 27.

PAT is apparently an herbal medicine I should look into. They also imply that KOR agonists act as I expect they do, but I'll need to read the full study to be sure.

Edit: yup, it appears that chronic KOR agonism is probably a good idea.

from full text "Utility of KOR agonists is a promising pharmacological tool for attenuating morphine tolerance (Pan, 1998), however, it is difficult to find effective KOR agonists that are devoid of dysphoric and psychotomimetic adverse effects in humans"

This is the cited study.

Fascinating. However, this provides no insight into the subjective effects. However, it does reduce my certainty that any given combination of drugs (sharing these mechanism) will work. There doesn't seem to be consistent results with these L-CCBs plus opioid studies.

Yes. That also means that most of the rat studies I've been reading are useless for my purposes.

Weird and surprising.This plausibly implies that L-type calcium channel blockers may not be as effective as it first appears.

Consistent with rat data. This is from 1998. I'm sure there's more evidence by now. It's been a while since i researched this, but I think I've previously seen at least one other study.

Excellent. This implies that theobromine may help prevent opioid tolerance.

1. This the only difference between an SMTP alias and list; expanding recipients to RCPT commands is the same.

1. Another great example to highlight the difference between SMTP envelope and mail data: the envelope's MAIL FROM (see annotation) is different from to the mail data's rfc822 From:.

Sometimes "reverse path" or "originator" address is also referred to "backward-pointing" address (and those instances also refer to the MAIL command mostly).

The question, then, is whether the opioid receptors are involved at all in this upregulation. For example, it could be mediated by TLR4 or filamin A.
