    SE/30 RAM Banking QUESTION

    NEW sockets are CREAM colored... My old socket was black, and it also had metal tabs. Even so, only the new cream colored socket works with the ROM-inator II... Lastly, please read the following excellent post by @Kay K.M.Mods regarding motherboard warping...

    SE/30 RAM Banking QUESTION

    I do NOT advise the solder across the ROM SIMM pad suggestion at all because I tried it and had trouble. Why? Because solder flakes apart over time, and the flakes short out adjacent pins! No damage occurred on mine, thankfully, but it was pretty scary discovering that. As to why my Kay Koba...

    SE/30 RAM Banking QUESTION

    I paid Kay Koba to replace all the RAM and ROM sockets in one of my motherboards. All have metal clips. I can now use a ROM-inator II SIMM without issue, whereas before I could not. Part of the issue is most SE/30 motherboards are slightly warped, bulging ever-so-slightly downward due to...

    SONY MP-F-51W 800K Floppy Drive SCHEMATIC (vector)

    The original MP-F-51W bitmapped schematic can be downloaded here. All related schematics are downloadable here. Eugene Gillott from Canada created the vector version and gave me (JDW) permission to make it available to the public. Eugene said that he found some minor differences between the...

    BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

    I'm really hard to offend so you almost never need to worry about that. I was just saying that if we think deeply on this subject, we should ponder what our Macs are capable of. I myself am a 68K Mac fan. The only PPC machine I have, aside from a couple Wallstreet notebooks, is my pair of G4...

    BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

    Well, if we want to get that detailed, we also need to consider which 68K Macs might be able to achieve 10MB/s with an optional SCSI NuBUS card installed. Any thoughts on that?

    BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

    I hope it will max out the 5MB/s SCSI bus on my Mystic, but I will need to wait for @Kay K.M.Mods to inventory the new BlueSCSI v2 first!

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    I do hope @Zane Kaminski is okay. We've not heard from him in this thread for a long while. Please tell us you're still alive and kicking, Zane!

    Make the Apple IIe Option Card software 32bit compatible?

    I lack the skill set to do that, sadly, Ron. But I am hoping right alongside you. Because honestly, I really don't like switching off 32-bit addressing and restarting whenever I want to use my Apple IIe Card and then want to use Mac apps which require more memory than 24-bit addressing allows...

    Make the Apple IIe Option Card software 32bit compatible?

    Which implies it is a technological oversight by Apple that may one day be overcome by some savvy vintage Mac programmers. I can only hope so, Ron!

    Help with gone wrong recapping attempt.

    I have no idea what that $100 Hakko model is, but if it is a FX-888D, I see in the =1&s_keyword=FX-888D#resultAnc']manual that there are 3 transformer versions, which mean 3 different product versions:

    Help with gone wrong recapping attempt.

    I don’t doubt your word, but I would love to see an eBay link to such a deal. Even so, $200 is really pushing the upper limits for the average hobbyist. And based on what you said that doesn’t appear to include both the heater and the hot air station. So I believe this is really why most people...

    Help with gone wrong recapping attempt.

    I've actually never used a preheater, mainly because of cost and the fact you need to have a rather large one to better ensure you can preheat just about any motherboard you will need to work on. I actually saw a "hot plate" in a video by @Branchus, and bought one, but it came crushed (from the...

    Help with gone wrong recapping attempt.

    I don’t mean to be critical whatsoever but I’ve always been curious about the twist off method. The reason why it always worried me is because you don’t always know the pad integrity. The pads need to have some level of adhesion to the PCB in order for the twist off method to even work. But if...

    Help with gone wrong recapping attempt.

    I must say, that is a great video. And yet, after all that work, he replaced the leaky electrolytic capacitors with new electrolytic, rather than choose a replacement with a solid electrolyte capacitor which will never leak. Oh well, at least they will likely get 20 years of use out of it...

    BlueSCSI Issues - Bus Error

    I have 3 BlueSCSI devices. Two are the internal type, and one is DB25. Two are version 1.1-a hardware (with STM32F & WCH clone chips) and another is 1.0-c (STM32). I have flashed them with various firmware updates over time, and now all are running the newest Dec. 2022 firmware without issue...
