Re: [M100] Hello Model 100 friends!
Welcome to the list Jesse :-) We've been geeking out about the ideal "model 100 replacement" for decades here... glad to see someone doing it! And when you are ready to sell anything, you're welcome to do so here. No problem. -- John.
[M100] Hello Model 100 friends!
I found my first TRS80 Model 100 about 5 years ago and never stopped playing with it. I now own many accessories, two units and perhaps loved the unit so much, I made my own... https://ready100.com I'm not here to sell anything (I'm actually sold out right now!) but I am here to meet this wonderful usergroup to talk to you about RadioShack and READY! my spiritual successor to the TRS80 M100. I am happy to have finally found you all and I look forward to chatting! Sincerely, *-Jesse Lafleur* *READY!*

Neat!! Appreciate the detail and random test-reply! I'm sure I can put this to use. On Sat, Apr 10, 2021 at 1:38 AM Brian K.

Many, many years ago on a distant shore Men did gather secretly beyond a hidden door What's more appropriate for soldering than heavy metal and songs about hell? It's literally lead, and it's literally hot enough to melt, and there's even noxious fumes. Soldering is metal af. :) Got a technique pretty much down for making dip legs on pcbs out of plain gold plated brass jewelry wire. https://photos.app.goo.gl/mQnsaH5LVoQW2RdJ6 Stick a dip-28 machined round socket in a breadboard. Cover the top with a piece of painters tape. I'm using green Frog tape, but anything like masking tape or blue painters tape will work the same. Set the pcb on top of that. Poke the brass wire down through the top of the pcb in one corner via, punch through the tape, into the socket, and bottom it out in the socket. Snip the wire flush with the top of the pcb. Repeat for the opposite corner. Add flux and solder those two legs. You only need to touch the heat to the top, The flux will tak ethe solder down into the via and the tape will keep the solder from going down into the socket. 2 or 3 seconds is generally plenty. Then repeat just the poke & cut steps for all other legs. Then solder all legs. The wire you want is 26 gauge gold-filled brass, half-hard. "gold filled" is like gold plated but way more gold than we actually need, but no one seems to sell merely gold plated wire, just bare brass or gold-filled. 26 gauge is thin enough to fit into machined round sockets and not even theoretically harm any sockets by stretching them out like ordinary square pins do, yet strong enough to inserted into connectors without bending. Prices vary pretty widely for the same product, so you should shop around... These are some that I actually purchased and tried and they work well: This is probably the most economical I've found so far: https://www.wirejewelry.com/round-red-brass-wire/26_Gauge_Round_Half_Hard_Red_Brass_Wire-14549-901.html https://www.amazon.com/gp/product/B07HCMYWGN?psc=1 https://www.ebay.com/itm/Red-Brass-Wire-Round-Half-Round-Square-14-16-18-20-21-22-24-26-28-Gauge/123161530578?var=423571461737 https://www.ebay.com/itm/26ga-Gold-plated-copper-round-wire-4mm-015-create-wire-wrapped-jewelry-pw023/203158831071 This one (below) does NOT work well, but only because it's thinner than 26 gauge despite saying 26 gauge. Perhaps 24 gauge from the same supplier would be perfect. Even this does work, just the legs are a bit thin and weak. They still do manage to insert into even fairly stiff sockets without folding, so really, you could use this just fine. And the thin/weakness of the wire does have a benefit that when you bend the legs accidentally from handling the finished object, you can just bend them back and they don't break off. https://www.amazon.com/gp/product/B07S9JFK2V This one works but is a bit softer than ideal. It does say copper not brass, so it makes sense. However, "dat price tho"... Stiffer brass is better, but this does actually work. It's just a little more delicate about punching through the painters tape. The legs insert into sockets just fine. https://www.ebay.com/itm/26ga-Gold-plated-copper-round-wire-4mm-015-create-wire-wrapped-jewelry-pw023/203158831071 And you want to avoid any that say "tarnish resistant" or "gold color", because they will actually be aluminum wire with an enamel coating. Example of what at avoid: https://www.amazon.com/dp/B077ZP7H4C Exmple of what to get (I didn't actually buy this one, it's just an example that meets the criteria): https://www.amazon.com/dp/B06ZZ83F5N The advantage? The point of all this? Actual micro-pins from MillMax or Keystone are around $0.10 per pin in small quantities and don't go down very much in larger quantities. Punched sheet leadframe pins from TE-Connectivity are also about $0.10 per pin, and those are only tin plated not gold. This method uses under 6.0mm of wire per pin (I measured 5.88mm average over several pins). You can get 15,000mm of gold plated wire for $3 plus $3.50 shipping from the ebay one above (49feet $2.95) That's 2,500 legs for $0.0026 per leg, or $0.07 for an entire 28-pin pcb. And the time/care/effort needed to do the job is actually about the same for all 3 options. Hey gold & brass... more heavy metal. (The first two lines in this email are the first two lines in the most ridiculously over the top caricature of a metal tune I ever heard. So is the album art. Metal Church by Metal Church.)
