@iPhil64 Very nice gold-plated sockets! Did you buy those individually from Mouser? If you bought them in a kit, I could add a link to that in my BOM as an alternative to the kit I link to right now. I bought the double-wipe socket kit because Kai told me double-wipe makes getting the chips...

Kai, if someone skilled in 3D could make a single, high-quality tool that can fit all the required resistors, 0.1uF capacitors, inductors AND those axial capacitors too (for SE Reloaded), that would be the lead-bending tool to die for! 🤩

This 4pc set on AliExpress might cover the axial caps, but frustratingly, all the makers of those lead bending tools do not put exact measurements for buyers to ponder! I therefore cannot determine if the body length of the axial caps will fit, or if the diameter of those axial caps will...

As shown in my BOM on page 4, U11D is the VIA chip (p/n: W65C22N6TPG-14 and wickedly expensive!), and U4D is p/n: SN75150P. Both are shown in my Mouser Cart -- a link to which is in my BOM on page 5. That chip info is 100% accurate regardless of SE Reloaded board silkscreen markings.

@iPhil64 I was looking through your photo album again today. Do the axial capacitors fit your Lead-Bender Tool?

Pretty neat, @retr01! Here are a few random thoughts (not trying in any way whatsoever to be critical, mind you)... When it comes to the early 1990's, emoji's did not yet exist. Twitter and its character limit didn't exist then either, and people were not offended by a lot of text. As such...

In my BOM just now, I have added that DigiKey has "limited stock". I also added a note in my BOM to warn people about Phoenix Enterprises' min. order amounts.

Interestingly, the spiral bound Troubleshooting Guide that I have is also water damaged. It's so bad in places that some pages are permanently stuck to each other, which means it must have been sitting in a pool of water for quite some time. You can see a little of that on on some pages in...

It is terrific. Thank you, @Elemenoh for your excellent work on that 3D design!

@pocketscience very kindly shipped me a Cartridge #4 which he painstakingly created. This is a finished cartridge with PCB, programmed main IC, and black 3D printed housing too! It's matte in tone and very slight rough, which is great to avoid showing fingerprints. I love it! I intend to...

Sorry, I misread the earlier post. I now see that Phoenix Enterprises does sell the SIMM sockets individually to customers in the US and Canada (with an unfortunate $30 minimum order), but they blatantly discriminate (for zero good reason that I can see) against anyone outside those two...

If @Branchus and/or @MacEffects commits to selling the SIMM sockets, I shall promptly remove Phoenix Engineering from my BOM and replace that link with theirs. I suppose one could, in theory, desolder the stock sockets, but the one's you sent to me, Kai, with the metal tabs are the ones to die...

Here are the LED test circuits I was pondering earlier... Closing the switch causes the LED to light in both cases. But that assumes it is a BJT transistor. It very well could be a MOSFET transistor instead. Yes, that 12V marking means 12 volts... In light of that, it's probably a PNP...

Thank you for your kind words, and I apologize I overlooked the content of your opening post. I don’t have a schematic, and I don’t have that particular drive in front of me right now. But since you were able to swap out a chip on the PCB, you would be experienced enough to do the following. I...

I have renewed my Mouser Cart with all in-stock caps as of right now. Get them soon, while they're in stock! :-)

That's probably the only reason it flows better than the 60/40, but the flux residue doesn't look too bad in your photos. Could be that it spits so much because it has less Rosin in it, in which case it will be easier for the IPA to clean off later, when you finally clean the board. My MG...

Mouser troubles me greatly. I spent a lot of time updating carts. And sometimes I’ll update a cart only to find one of the capacitors I updated then goes out of stock the next day, even though they were hundreds in stock at the time I replaced it! It’s crazy.

@Kai Robinson what is your experience with Phoenix Engineering? It seems clear I need to update my BOM with another source, but I’m not sure what link I should use. You are probably going to run out of those sockets pretty quickly.

The link to those in my BOM leads to the DIP IC... https://www.utsource.net/itm/p/11226849.html Are you saying that is the exact item you purchased but you received the SOP package due to a mistake by UT Source? If so, you need to contact them about that. I agree. Plus I am concerned...

I just measured. They both measure roughly 16Ω.
