Thanks for your kindness, Jeff. I suspect he may not have any issues at the stock 50MHz speed. In my case, I have a stock 40MHz Daystar Turbo040 card for my IIci which I later overclocked to 44MHz via XTAL swap, and it was after that XTAL swap the 400K and 800K floppies became unreadable...

Thank you for the helpful feedback, Jeff! Sadly, even if I ignore HD20 mode on the FloppyEMU, the fact remains that 400K and 800K disks no longer work on the overclocked Turbo040, which is a problem that I am not sure I want to live with. But if such could be fixed by a hacked ROM SIMM, then...

I wish to thank David Cook for his excellent post over at the 68kMLA, as that served as my inspiration for overclocking the Daystar Turbo040 in my Mac IIci. Overclocking is done by a mere XTAL swap. (And the Hakko FR-301 desoldering gun makes the job easy, I must say.) Because David was able...

I'm at home now on my MacOS Sonoma M1 MBP, and it works great. The top part of the dialog is not cut off either. So the problem I reported in my previous post about the top part being cut off seems to be exclusive to MacOS Mojave. Not a major problem at all. I just wanted to mention it...

Very interesting. I'm here at work right now on my late 2015 5K iMac 27", and I am definitely running version 3.0 here. Sure enough, no problem. So I guess I was using an old version at home last night. One thing I do notice though on this Mac OS Mojave machine is that the very top content...

@OneGeekArmy I did my first test of the Apple II features today. You edited your opening post to say the following: Look inside DOS 3.3 disks Unfortunately, I am not able to get a file listing for my DOS 3.3 disks. ProDOS disks do work, however. Attached is a ZIP archive for you to test...

A well deserved nap too! Absolutely amazing work.

People who have boards with those white caps installed are lucky because they don't need changing. Too bad Apple didn't make all board using that particular cap!

Some time ago, OlePigeon over at the 68kMLA let me post photos of his boxed HyperDrive kit on my Flickr page, which you can check out here... https://flickr.com/photos/66071596@N00/albums/72157718814035061

Thank you for sharing that wonderful story, @MichaelLAX. And welcome to TinkerDifferent!

I also see that Console5 does in fact offer a recap kit for the Astec AA7341B: https://console5.com/store/apple-2c-power-supply-cap-kit-p-n-699-0230-astec-aa7341b.html That page provides a link to their cap-list WIKI, which explains the capacitors included in that specific cap kit...

A 1000µF 25V capacitor located just outside the PSU should also be replaced. It is green in the photo below...

No, it did not have the firmware installed before I soldered the PICO W to the BSv2. And after it was soldered, I connected the USB cable, but as I said in my earlier post, it would not mount and therefore I could not copy any firmware to it. I then desoldered it and was able to copy the...

I can only say with near 100% certainty that my soldering job was not the issue to the problem I reported earlier. After I installed the firmware, that was the resolution to the problem. Whether that firmware install be done in the PICO W alone or while soldered to the BSv2 board, that...

I’m happy to report it is now working in my IIci as well. So I guess when telling people how to swap out their PICO for a PICO W, it’s important to tell them to first update the firmware on the PICO W and then after that solder it down. I also tested both of my BSv2’s without the power...

Well, I guess the UF2 file must indeed be the "firmware" mentioned by @Androda because I just finished soldering the PICO W back to the BSv2 board and then tested on our PowerMac 9600 at the office, using the excellent OverEasyII SCSI adapter by @Stephen . Booted the 9600 right away into System...

@Androda I sincerely appreciate your kindness in providing such a detailed explanation! QUESTION I downloaded this *.uf2 file from this page. Those UF2 files are the "firmware" you spoke of in your post, correct? If so, it is good because it's installed on my PICO W. At least, I think it is...

One last question before I solder the PICO W onto the BSv2... When I put back the regular PICO on the BSv2, the pins make good contact, such that I can press the button on the PICO and connect the USB cable to my Mac. And as is the case with the PICO W, the regular PICO too causes both LEDs...

Perfect advice. Thank you! I just copied to *.uf2 file to the PICO W and it ejected, as expected. The tiny GRN LED nearest the USB connector flashes 5 times repeatedly. I will solder it back to the BSv2 and then test later tonight. I appreciate your help.

@alexADB Before doing anything else today, I used my DMM in Continuity Check mode to touch every adjacent pair of pins. None were connected together. After that, my Hakko FR-301, combined with the fresh solder I had applied when soldering-in the PICO W, made quick work of desoldering the...
