    Airport card doesn't see any networks (G4 Cube)

    Airport Card Question. I found a card at work in the original box, in great condition. I've got it installed in my G4 Cube for now so as to test it. Card is recognized. System Profiler shows Firmware 9.52. OS is 10.4.11. PROBLEM: "Wireless network not available." Card is "turned on" as per...

    Apple TechStep Replacement ROMs, cartridges, software, and more!

    Just to let everyone know (even though it's written in the Parts List RTF file, the connector shown in your photo is in stock on Mouser right now ($2.90 for 1pc, shipping extra).

    Apple TechStep Replacement ROMs, cartridges, software, and more!

    Just to clarify, I am not trying to be critical. In am simply thinking how to hand-hold newbies to get from point A to point B. Newbies may come along and find this thread, then want to know how to easily build a cartridge. So I was thinking of a step-by-step approach to aid them in achieving...

    Apple TechStep Replacement ROMs, cartridges, software, and more!

    Thank you for the clarifications. Basically, one should not use an Assembly service because in order to use that programmer, you would need to socket the ROM chip, program it, then solder it in. In other words, one should do the soldering assembly themselves. I don't see that as a big issue...

    Apple TechStep Replacement ROMs, cartridges, software, and more!

    Before I begin, I just wish to express my sincere amazement and appreciate of this amazing project. The work that went into making this a reality is simply astounding! I now have some questions and comments about the contents of the attachment in the opening post: Let's go about this...

    Identifying and confirming fake 68040 CPUs (especially the L88M mask)

    If you like, you can do a copy/paste of your excellent table content as an Article (if some folks would find that more helpful), because unlike a certain other forum which shall not be named, you can Edit posts here on TinkerDifferent. 🥳 "Articles" in the "Resources" section are especially made...

    Identifying and confirming fake 68040 CPUs (especially the L88M mask)

    Going under the assumption that all of Eric Woo's chips really are authentic pulls and not rebadged, I have a couple questions (which we may or may not have discussed privately by email in the past)... 1. Have you tried using thermal tape and a heatsink (applying it and then removing it) to see...

    Identifying and confirming fake 68040 CPUs (especially the L88M mask)

    That kind of testing is the best you can do to determine if it has the full FPU. The next step is to see how high you can overclock it using the fastest VRAM possible and board recapped with the best capacitors. Then you just need to measure the temperature of the CPU while running an...

    Identifying and confirming fake 68040 CPUs (especially the L88M mask)

    More specifically, adding the CPU to your computer, then switching on power and launching an app like Norton System Info (or another benchmark utility) which will tell you if the FPU is present or not.

    Identifying and confirming fake 68040 CPUs (especially the L88M mask)

    But where would you be able to reliably and consistently purchase those authentic K63H mask versions online, Kai?

    Identifying and confirming fake 68040 CPUs (especially the L88M mask)

    Just goes to show that observing a seller's feedback alone is insufficient to determine if what you buy is the real deal... When viewing your photos, @Mr. Fahrenheit, what specifically must web observe which proves they are fake? (I ask out of ignorance here... not trying to be...

    Macintosh SE Motherboard Photos wanted

    It probably is the case that the August 1989 revision of the SE which introduced the 1.44MB "SuperDrive" included a mere ROM and SWIM upgrade, not the motherboard upgrade. In other words, I am guessing that the 820-0250-A motherboard came out prior to August '89. That makes sense because the...

    Very interesting. You have the newest revision 820-0250-A motherboard with the older ROMs and older IWM chip. Makes me curious what percentage of newer edition "A" boards Apple shipped with the older edition chipset trio. I've also noted that your LO ROM is 344-0041-B, which I guess is older...

    While I won't use it in my video, for the sake of reference, I would appreciate seeing a clear photo of what you have. You have me curious! :)

    Macintosh SE Motherboard Photos wanted

    Friends, I wish to thank each of you who kindly contributed photos. I now have what exactly I need... Old SE Board 820-0176-B, with Old ROMs, Old IWM (thanks to @MacMaster for the board photo): (I added color corrections and sharpening only.) New SE Board 820-0250-A, New ROMs, New SWIM...

    Macintosh SE Motherboard Photos wanted

    Now that board and photo are pretty amazing. No RAM makes it easy to see the resistors used to set RAM size. I love the old soldered battery type! A truly well-shot photo without pretty much no distortion! I've color corrected and sharpened it, as well as cut out the background, which you can...

    @Branchus Thank you for kindly checking! I certainly appreciate your time. @chrisangellis Although the RAM SIMMs are installed in your old version board, I can see the RAM configuration resistors, so I believe I will be able to use that. Here's how it looks after a few edits... @rikerjoe...

    A hi-rez, top-down photo of that older unmodded board would be great, Kai. Thank you. Not sure how @Branchus took his great photo, but in my case, I put my camera on a tripod and faced the lens straight down. I extended my tripod to be fairly tall so I could put distance between the lens and...

    Hello, friends. I am in the middle of editing Part I of my @Kai Robinson SE Reloaded video, and I am trying to find high resolution, top-down photos of the SE motherboard and chip sets that are different from mine. Here's a high resolution (20 megapixel) photo of mine, which is revision...

    "Spicy O'clock" project has started

    You prepared those faster than I thought. Wow. That basically means overclockers have the 60ns VRAM from Mr. Fahrenheit and now the SMC 60ns VRAM. Now there are fewer excuses to make those old 68040 Macs faster with Spicy O'Clock!
