What the other comment here

[@johnpossum556]

This info may be dated but back in the day when we wanted to keep our TRS-80s looking fresh there was a grey cadillac paint that matched. Key to the shoulder is a mild strengthening program once you get your shoulder unfrozen.

[@mwwhited]

As a way to sort components ICs, active and passive components... I used 4 inch binders with playing card sheets and antistatic envelopes. It made a pretty clean way to file components without having a mess of those little flip out draw cabinets or sorter boxes. They also fit nicely on bookshelves which is great as my current "electronics workshop" is my home office. I do still have some of the larger components in a stack of sorter boxes but it's far fewer and much more organized with the binders.

[@tarzankom]

As someone who deals with chronic back and neck issues, I can totally relate to being unable to move heavy things on occasion. It can be frustrating. I hope your shoulder heals quickly.

[@peterjf7723]

I had a frozen shoulder in 2014, my GP sent me to a physiotherapist who diagnosed a rotator cuff injury. She went on through a series of strengthening and stretching exercises for me to try. With the exercise plan I started to feel better after a week and was pain free after four weeks.

[@MattKasdorf]

Yeah, don't knock physio. I had some nasty vertigo, and the meds were complicating the situation; after just two odd / strange neck stretching exercise sessions (NOT chiro!) it started to lapse. Three weeks later I was functional again.

[@peterjf7723]

@@MattKasdorf I had some unpleasant reactions to corticosteroids so can't really take them. Last time I took them my vision was disrupted. It caused fluid bubbles to form under my retina. The consultant at the eye hospital knew almost at once what the problem was. My regular family doctor had not heard of this, luckily cthe consultant had given me copies of papers about this.

[@parrottm76262]

Ugh, frozen shoulder! No! I have both shoulders frozen, and people have no idea how debilitating and painful those can be. If you have the choice of going under anesthesia and having the shoulder 'cracked' by an expert, I highly recommend it. I had that done on my second one after doing the whole physical therapy only approach and it took forever. My best to you. So glad the Model II keyboard has been updated!

[@sprybug]

I use those craft storage containers, that can typically have several to a few dozen spaces inside, to store my IC chips. I have different ones depending on the IC type. Each space I label with a sticker on top. I have a big one for 74 series logic, one for video IC's, one for audio IC's, one for CPU's, one for RAM, one for Comparators, etc.

[@robertsissco2439]

I don't have that many, I just have one such box and have it separated by system, so I have a C64, a PET and an Amiga space in mine. Works for me since I don't have a lot of extra chips.

[@mal2ksc]

I use a container that was repurposed from fishing. ICs and components are about the same size as sinkers and hooks, so the spacing between walls is pretty close to ideal.

[@sprybug]

@@mal2ksc Yeah, that can work as well as long as you don't end up shifting it around a lot and turning it sideways, etc. I typically store my containers on its side, so it's important for me not to have any gaps between the lid and the dividers or else components will start spilling into other compartments and that would just make things poopy!

[@mal2ksc]

@@sprybug In theory, I could turn the tackle box sideways and the partitions would hold everything in place. In practice, the lid will bow under the pressure and things will become, as you say, "poopy". A short stint on edge is probably fine, but long term storage is not.

[@idj20]

Seriously, I love your soothing and relaxing approach to things in your videos, including this one, as I watch them pre-bed time - and yet you still hold my interest right to the end. All said with respect, of course!

[@Jennifer-pk4wq]

I'd watch you organize and label your workshop! My current system: I bought a lot of storage boxes with lid and individual compartments that you can pull out, each box gets labelled by general type and each container has a label with the part (using a handheld label brother label printer). I have color-coded several types of components to find them easier. And if something doesn't fit the containers in the storage boxes, I will custom print the containers. I find that if you have everything labelled, it's easier to find it by looking at it - Using a computer can be super useful for inventory keeping, but that means whenever you need to sort it in or check something out, you need to switch context.

[@horusfalcon]

Wow! That's a lotta chips and DIP! I like mwwhited's suggestion of using binders. Seems like it would be high-density and easy to organize by type.

[@catriona_drummond]

Yeah! The community is responding with helpful tips for organizing! The binder one sounds really cool but I know what you're saying, you need a taxonomic system like a card catalog or cross reference database and that is what takes an inordinate amount of time to sort, organize and physically coordinate. Maybe ask your compatriots/patrons/friends if they could lend a hand in compiling lists and coordinate little chores like creating the master database or making labels from photos of your actual sets of chips, and have physically close, trusted volunteers taking said photographs or lending a hand with labeling and shelving the chips? Just some suggestions and I understand if you're uncomfortable with any of it. Just want to see how I might be able to help.

[@jeromethiel4323]

You are making me want to break out some of my old TRS-80's, and see what still works. I went through a period where i was buying a lot of vintage 8 bit machines. I have several TRS-80 model 1's, some which have some of the modifications that made the machine better. One has the extended edge connectors soldered onto the crappy expansion port so that it is now a gold plated connector. Something that savvy TRS-80 owners did back in the day as the solder coated expansion port connectors were VERY prone to oxidation and crazy intermittent problems.

[@brostenen]

For a couple of years now, I have used acetone like you used. And I have this plastic paste, that I have made, mixing a bit of acetone into bits and pieces of ABS. The paste is good to fill out holes and groves to make a smooth surface or finish if you like. I also use another trick that I learned from scale model build hobby. Using super glue and baking soda, makes a hard cement type result. But it is difficult to use, as it hardens in a second. But the trick is usefull for a select few situations.

[@TheSudsy]

Adrian, get some putty or plasticine in the broken base and make a mold with plaster of paris or similar and make an epoxy mold to fill the gap. You now have a perfect example to mold from and two bases.

My very first computer was a home-brew using a couple of the 2114 chips to give 1K x 8 bits and using an old 8080A as the CPU. It never needed more than 1K since programming it was accomplished using binary input switches and getting the output was done through LEDs. The Thirteen Steps to Programming and Running the Home-Brew Dinky Little Thing Computer: 1. Ensure the run/hold switch was set to "hold." 2. Switch on. 3. Use the binary memory location switches to set the memory location (0 was the default after-reset start location). 4. Use the binary data switches to set the instruction or data. 5. Click the read/write switch momentarily to "write." 6. Repeat steps 3 & 4 until the entire program was in RAM. 7. Turn all address and data switches off since only that position had isolation diodes. 8. Push the reset button. 9. Switch the run/hold switch to "run" momentarily then back to "hold" since there was no way to tell if the program had finished (but computers run so fast anyway that a short program would run in a fraction of a second). 10. Set the memory location for the result using the binary memory location switches. 11. Click the read/write switch to "read." 12. Read the LEDs to obtain the results in binary. 13. If the answer was more than one byte in length, repeat steps 10 & 11 until you get all of the result. Fun times.
