    Brand New SE/30 Logic Board

    I believe I read that once the caps are powered on, the process of leaking accelerates. I definitely second tanaquil on replacing the caps. They will fail.

    Software for Mac SE

    You may want to investigate installing the Connectix Ram Doubler system extension which allows you to create virtual memory and double your 4MB of ram to 8MB. I think the "RAM" is taken from a chunk of disk space, but it certainly makes my SE/30 better to use. I cannot remember if I used this on my SE before I switched out the motherboard for an SE30 one, but this would certainly help (assuming it is compatible). You can run System 7.5.5, but it is almost painfully slow to use.

    eMMC or SD better for Pismo 500 down to PB190 . . .

    I have seen several very small 2.5" IDE to SD adapters online, but I am not sure whether or not they would be bootable. These would make for very convenient drives as compact flash has much higher pricing than SD cards. Here is one on Amazon: https://www.amazon.com/QNINE-Adapter-Memory-Converter-Laptop/dp/B01N33LAVV/ref=sr_1_3?ie=UTF8&qid=1529770999&sr=8-3&keywords=ide+to+sd

    Macintosh SE fan noise

    The SE had two fan variants: One that is a standard size computer fan and one that is very different. As long as your SE has a standard fan, it is as simple as undoing some screws and desoldering some wires from the analog board. I tried replacing my fan a while ago with one of these: https://www.amazon.com/gp/product/B00006B8E7/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 It did not reduce noise very much and it is still quite loud; I would not recommend it. I think the problem is that the SE has no fan control and runs everything at 100% power. It might be possible to add a strong resistor or potentiometer in line with the fan to take some of the speed/noise down, but I have not investigated. I do know that Noctua fans are much higher quality and might still be quiet at 100% speed.

    Mac SE internal floppy won't recognize disks

    I would first recommend lubricating the floppy drive in the SE along with cleaning the drive heads with isopropyl alcohol on Q-tips. This will probably fix things. The drive may not be able to move into all of the positions of the floppy disk, so it reports it as corrupt. It is possible that you somehow misaligned the drive heads when you replaced the eject gear. The drive would then be out of sync with the data on the disk and report it as corrupt. This can happen if you pull the heads too far apart from each other. This would also deform the drive head springs and prevent them from pressing down on top of the disk the correct way. I do not think it is possible for the user to realign the heads, and doing so will probably cause more harm than good. For lubrication and drive cleaning, I recommend following this tutorial: (pay attention to the "clock position" part of the eject motor he talks about -it may also be incorrect from before.)
  6. KeenerB, Although the FloppyEmu does Macintosh HD20 hard drive emulation, it is not compatible with an SE/30. It works on the other compact macs prior to the SE/30, but compatibility for the HD20 is not implemented in the ROM of the SE/30. (I think you can buy a 3rd party compatible ROM, but it costs just as much as a separate hard drive emulator.) I suggest looking at the SCSI2SD for hard drive emulation -it is a little fiddly to set up, but it works extremely well once it is. If you haven't already, I would definitely recommend following a floppy drive lubrication tutorial before trying to use the floppy drive and boot off of any floppies. An unlubricated drive can strip the teeth off of the gears in the ejection motor. There are replacements available on eBay if this has already happened, but it is best to avoid altogether. I have linked a great tutorial explaining how to do this. Good Luck!

    Connecting a Macintosh iisi to a VGA monitor

    Thanks for the suggestion: I cleaned the entire computer and motherboard thoroughly with isopropyl alcohol, but unfortunately it had no effect. I need more information about the way the IIsi works with displays before continuing with recapping.

    Connecting a Macintosh iisi to a VGA monitor

    I attached the CRT to my G4 Cube with VGA and was able to run the display at 640x480 60hz, but the G4 would not let me set anything lower. (I think I read something about 15hz?) I took a closer look at the IIsi and realized that it does not have a boot chime. This probably means there are some capacitor issues with the computer. I would like to determine if I can even theoretically use the computer with my monitors before attempting a re-cap. (there is no noticeable damage after cleaning the board) I re-read a post above where a Pivot Cable was mentioned: what is the purpose of such a cable? Can someone explain what the Pivot Card does and how to use it? -I am not sure I understand. I do not know where to continue from here. Thanks for all of the help!

    Connecting a Macintosh iisi to a VGA monitor

    I have a PowerMac G4 that can probably run the screen at 640x480. I am unsure whether or not the G4 will run the screen at the same frequencies necessary for a IIsi. I will test it out today.

    Connecting a Macintosh iisi to a VGA monitor

    I did a ton of troubleshooting with my monitor adapters, and I was not able to get anything to display on the screen. My Belkin adapter looks the most promising, but it is missing a plastic knob which might be necessary for use. I am unsure whether or not this makes a difference, but I have a Radius Color Pivot IIsi Video Interface Card. Does this fix the video subsystem issues? I have no clue how to use it or if I can set it up without first using the computer normally. I looked up the model number of my CRT (Dell 781s) and found this: https://web.archive.org/web/20011220004743/http://docs.us.dell.com:80/docs/monitors/688en/en/spec.htm#General I appreciate the help, and I really hope I can get this to work!!
  11. I am having trouble setting up my Mac iisi with a monitor. I do not own any compatible DB15 Apple monitors; however, I have a Dell CRT monitor with VGA. I also have a few different DB15 to VGA dip-switch adapters that seem suited for this task, but I am unsure what settings to use. Do I need a specific kind of CRT to use an adapter, or are they plug and play? I have read that only specific LCD models work, but I am unsure whether this applies to CRTs. I have never seen this computer work before, so I have no way of changing settings within the operating system. In theory, I have everything necessary to use the computer. I just need to configure it properly.

    Connecting old Macintosh to the net using serial

    After trying these troubleshooting steps, I still cannot connect to the internet or establish a connection to my iBook. I completely uninstalled FreePPP and replaced it with a fresh install of MacPPP 2.0.1. I do not have ethernet in my workshop, but I tried sharing the wifi connection of my MacBook through ethernet to the iBook. This gave the iBook an IP that started the same way as everything else. My router became 192.168.1.1 and the iBook became 192.168.2.2. The SE/30 remained 192.168.0.123. Do I need to change the address I created for the SE/30 to something specific? I am not sure whether or not my serial functionality is working. I now am running the command with tty.usbserial instead of cu.usbserial. When I press open on the SE/30, the computer says it is establishing a connection and a while later that the link is dead. I am not sure why it is not working. Something interesting is that MacPPP and FreePPP have different max baud rates. FreePPP has a max of 230400 baud, so it would be nice to use in the future. There are additional settings within MacPPP that you did not mention. Do I need to change any of these? In MacTCP, there are also checkboxes for something about subnet masks. Which do you have checked? Is there a general way I can verify my serial adaptor and computers are working? I have never seen this SE/30 online before. I still am not using a proxy, but I think I need an initial first connection with the iBook before adding that. I appreciate the quick and detailed response to my wall of questions. This will be very exciting once it works.

    Connecting old Macintosh to the net using serial

    I have just tried this out with my iBook G3 running Tiger, but it is not working quite yet for me. I have a USB to RS232 adaptor (similar to the one you linked) connected to my iBook and to the modem port of my SE/30. I installed FreePPP on the SE/30 and set it up the same way as above. I am using FreePPP as referenced in the old guide -would using MacPPP as listed above make any difference? MacTCP is configured the same way you described; however, I was not sure what to enter into the Gateway Address box. I have an AirPort Extreme set up for my iBook as it does not like my modern router. Should I use the IP address of my modem, router, or AirPort? On the iBook side of things, I am running OSX 10.4.11 which I figured would be the most similar to what the original tutorial was using. I installed the same drivers from Prolific, (they still host them on their website -no archive.org required) and I plugged the adaptor into the computers. When I plugged the adaptor into the iBook, it opened a new menu in the Networking panel of System Preferences listing a ton of settings specifically for a USB serial device. Do I need to change any of these settings? When I ran the code from the other thread, I received errors about the KeySerial1 device. I assumed I could change that to cu.usbserial as that was the way the computer seemed to detect the adaptor. This did not seem to work. Is there a way to find what I should type in after the baud rate? I also changed IP addresses so they corresponded to the laptop IP and the SE/30 IP. Was the IP of the SE/30 the same as the 192.168.0.123 from before? I am also concerned that there may be an issue between using a 10.0.0.0 address and a 192.168 address. I pressed connect on the FreePPP after running this command but I received a message stating that the connection did not work. Is there anything I am doing wrong? Do I need to use the PHP Proxy Script? I really hope to get this working as it seems like great way to connect my mac to the internet.

    Bridge Mac

    I would like to clarify the current functions of Zip Drives: With the most current releases of MacOS (10.6 to 10.13), you cannot write to Standard HFS partitions. This is the file system used by the Compact Macs. There was a driver that allowed for this in newer operating systems, but it seems to have stopped development. My current process has been to download files onto an HFS+ flash drive, transfer the files onto an HFS compatible iBook G3 running OS9 and use a USB Zip Drive to transfer files to my older Macintoshes. It would be much more convenient to use my modern mac to write standard HFS partitions, but without drivers, this is not an option. Does anyone know a better way of doing things?

    List of Mouser part numbers for Color Classic Caps?

    The link for the DigiKey cart is slightly glitchy. (it makes a suggestion to buy more capacitors for a discounted price) If you click "View Options" under options, and then click add, the correct cart will be displayed. (it contains two other capacitor types)
