    A2 VGA Pi Pico - Which firmware?

    Sorry if I misunderstood your point, but if you are mentioning double heres mode, the output will not be correct unless pins 50 and 55 of the expansion RAM card are connected. Check them out. *In the case of a genuine apple 64K card, this is the AX1 solder pad.

    SMC ROM Simm programming

    Yea, I knew Minipro, as I mentioned before, if you are installing Homebrew for the first time, you should be using a newer MacOS (at least two generations older). I mentioned this a little further down in the thread. So, if you are using MacOS before Monterey, it will be a bit of a hassle...

    SMC ROM Simm programming

    I agree with that point, but I'm not going to get into an argument that has no end in sight lol Of course My main computer is a Macintosh, it has been 30 years or more. But you know, in Japan, iPhone market share is 60% now today. As a result, Macintosh's market share increased from 5% ten...

    SMC ROM Simm programming

    There was a way to run third-party apps using Homebrew, but that is a thing of the past. Mac OS changes frequently, so it is difficult to maintain compatibility. Even Homebrew cannot support two generations ago. Currently, Xgecu's successor programmer, T48, is the mainstream. As far as I know...

    Crucible for the SMC ROM SIMM

    This is designed to make our ROM-SIMMs convenient to use, so we hope you will use our ROM-SIMMs...lol. At that time, many manufacturers were trying to develop ROM-SIMMs, so we also needed to differentiate ourselves. Please understand. But...to recombine the four split files, the following steps...

    High resistance on Spicy O Clock

    As mentioned in the previous reply, this is the result of measuring with the probe point between A and B: Since B is connected in a row, it doesn't matter where you connect it to among the three pins: More details here...

    High resistance on Spicy O Clock

    Sorry for the confusion. I would like to point out that in the new PCB V.1.3 the number is plus 3.3K. So the value you asked for is actually 1.19K ohms... If you want to get the value according to the previous manual, measure the resistance value between the images.

    Arcade Cabinets - Restorations + Modifications

    Well done Drake! At that time, one play cost 100 yen. At the lowest, it was 50 yen. That hasn't changed since the late 1970s, but by the late 1990s it had dropped to about 50 yen.

    Apple II clone - screen full of apples on boot

    I think your clone's F8 ROM is 2716((IDK because there's no picture), so try burning that ROM and testing it. Try this: https://github.com/misterblack1/appleII_deadtest Dead test runs without using ROM (only with its own ROM). If there is something wrong with the logic circuit, the test will be...

    I myself can't think of anything elaborate:ROFLMAO:, but I can understand a little bit how he feels. When a lot of hard work doesn't pay off right away, unless it's work, you might want to leave it alone for a while. We are too greedy and in too much of a hurry. This is a device that can be...

    My bro @Drake pointed me to this thread and I decided to post here first. I got in touch with my friend Katherine Stark a while back to create a PCB for this device. I also knew on FaceBook that this PCB was announced by Chris Tersteeg, but I was busy with other things so I left it at that. I'm...
