    Booting Mac Plus with scsi2sd...

    Here you can find a description of a successful attempt: I used this and my plus booted from the SCSI2SD: And here is my solution:

    Macintosh Classic (one) with no power.

    Check the fuse! Check the solder points of the power cord connector. I had an analog board where all three were broken. Replace TDA4605, CNY17G, IRFBC40. Read "Mac Classic & SE. Repair and Upgrade Secrets" from Larry Pina. Read the shown thread and the links in the thread!

    128k Macintosh board is it worth much?

    I am from germany and would take it too.

    Death chime and Simasimac on Mac SE/30

    I had the same problem with my SE/30. After changing two of the F258 the problem was solved. For cleaning you can use vinegar.

    SE/30 display crashing to black with a raspberry sound

    Measuring the voltages:
  6. Recap the board. Cleaning with isopropyl alcohol or with a dishwasher will only help for a short time. The caps will leak again! More important is to remove the battery. If it explodes there will be more damages of the logic board.

    chime of death with D2 signal looking weird - any ideas?

    Could be the multiplexers. I had a similiar problem, changed the F258 and had success.

    Rusty Macintosh SE/30

    Perhaps the power supply needs a recap. Not Sony: http://www.maccaps.com/MacCaps/Capacitor_Reference/Entries/2015/6/1_Macintosh_SE_30_PSU_not_SONY.html Sony:http://www.maccaps.com/MacCaps/Capacitor_Reference/Entries/2014/10/9_Macintosh_SE_30_Sony_PSU.html I had a Sony and replaced one of the large caps with a snap-in-capacitor because I could not get another replacement. The height of the caps is a problem. You have to order the right heights or you can get problems with the case of the psu!

    Rusty Macintosh SE/30

    Looks like a problem with the ROM. Do you hear a chime? If not, some traces from the ROM are probably rotten. Then you have to check continuity of these traces. You need the SE/30 schematics. https://museo.freaknet.org/gallery/apple/stuff/mac/andreas.kann/schemat.html Did you clean the ROM socket and the ROM contacts? Another problem can be UE8 or the multiplexers (UI, UJ F258). But if the mulitplexers are the problem, then you often get a chime of death. Look for corrosion and rotten traces! Perhaps you can give us a photo of the board in high resolution?

    Macintosh color classic won't power on

    Did you try to power the CC up without the mainboard and pushing the mainboard into the slot then? Sometimes it works.

    Error 01FA00

    I think, that the disk is defect. It is not possible to write a 800kb disk with modern computers, you need another Mac like a SE or SE/30 to do this. There are some tutorials in the net, but you need a Mac with a superdrive or an external 800 KB drive to do this task. Was the floppy drive cleaned and lubricated? Sometimes cleaning the reading head with alcohol (isopropyl) solves some reading problems. I think, that the plus can read disks from OS 1.1 up to OS 6.0.8. What is the OS on your disk? Where are you from? Perhaps someone can send you a working disk? I can produce disks from OS 0.97 up to OS 7. But I am from germany. But also with a working boot disk you will have the problem to get software to your computer. Even for a serial communication, which can be a solution, you must have a programmdisk for your plus. When I came into this problem I bought a SE/30 with networkcard and an external 800kb disk drive. I can download software with my windows PC from the internet, put it in my own webserver with only standard html und download it from there with my SE/30 and Internet Explorer 3. This worked for me.

    Macintosh Plus White bars issue

    - Check the connector to the screen on the analog board. The solder is often cracked. Resolder the connector. Sometime the same happens to the board on the tube. - Give the side of the case with the analog board a little clap with your hand. Perhaps the screen will work then. Sometimes this works when the solder points are cracked. - Resolder the flyback. - Could be a problem with the RAM.

    SCSI2SD external cable type?

    As far as I know, there is not a printable design available. I only know the universal mount for intern installation. https://www.thingiverse.com/thing:3067337

    SCSI2SD external cable type?

    The micro usb is accessible, but I do not use it. The scsi2sd uses the power from the dsub cable. This works with most compact macs, but not with the mac plus. The enclosure was 3D printed with my own printer (Anet A8, 130 Dollar). You can get the stl-file from thingiverse.com.

    SCSI2SD external cable type?

    For my version 5 SCSI2SD I used the configuration shown in the pictures. Adapter: http://amigakit.amiga.store/product_info.php?products_id=1290 The cable is a 25 dsub (male-male, pin to pin) Enclosure: https://www.thingiverse.com/thing:1131419
