    Any more Information about how much you turned it up? I have not yet measured the 5 and 12 Voltage rails but I will do that when I have read up about how to do that - hopefully tomorow. Somewhere I read that one has to be very, very careful to not fry anything permanently when increasing the voltage. So I'm a bit afraid of doing so honestly.


    It was a while ago, but the voltages were a little on the low side, so I just turned the pot up a smidge while the computer was on and it instantly fixed it.  I had already recapped both the logic board and the analog board without any improvement in the wobble.  Someone suggested reflowing the solder on the analog board's monitor wires but that didn't help either.  Then I read somewhere that it could be due to low voltage and bingo!

    As much as I like those alternative solutions which can be helpful in a pinch, I am a stickler for trying to fix the original stuff and use that. 


    I'm all for original equipment, but my technical knowledge is limited to recapping, and if that doesn't work I look for a replacement...

    I'm thinking its a logic board or other connected item on the system drawing too much power from the PSU.


    Disconnect the fan, hard drive and floppy drive and see if it works without those things. If not, it might be a bad/shorted item on the logic board, usually a cap.


    It was definitely the power supply.  I did the mAcTX LC conversion with a modern power supply and everything works perfect now.

    What version are you on at the moment?  Error reporting is quite a lot better in 0.9.2 over the one mine came with (0.7.0), and generally it was a much smoother ride.


    I think I'm on v0.8.0, so I definitely need to upgrade.

    Anyone got anything they particularly want me to try out? @Byte Knight, I believe you have one of these too (IIRC), anything you'd like to add?


    Excellent review!  And now I know why formatted SD cards from my MacBook Pro won't work with the MacSD...


    With the ability to also use this as a CD emulator, I felt that this would work better as an external device that I could use with several of my vintage Apples.  So I ended up putting mine in an Apple HD 20SC case with an SD card extension cable - you can see the project here.  The instant power-up and no need for external power is a huge plus with the MacSD.


    The MacSD works exactly as it's supposed to with the included SD card (which was a nice bonus!).  I've even got it working with my Apple IIgs.


    However, trying to create my own SD card has been frustrating.  Every time I try to make a new SD card full of CD images, I end up with a bunch of CD's that aren't recognized, even if I copy those CD images directly over from the included SD card.  Maybe this has to do with the case sensitive issue mentioned by cheesestraws.  Also, I've had several SD cards get fragmented despite having plenty of space left on them.  


    Now I haven't upgraded to the latest firmware, so maybe this will fix some of my issues...

    gotta make due with whats around - needed something to hold it up while testing :D


    Also hello from South of St. Cloud! Could hand deliver you one next time I drive to my buddies house in Norwood/Young America :)

    It's a deal!  I was wondering what part of MN you were from.  We need to find a few more locals so we can have a LAN party!

    If you don't have any other bootable drives installed, the Mac will wait for RaSCSI to boot up. So, you might see a flashing question mark for 10-20 seconds. But, the Mac should boot once RaSCSI starts up.

    RaSCSI has that too. I didn't get around to testing it until a few days ago, so I hadn't been advertising it. Next to the ACT/ENB LEDs there are two holes for a header.  You can hook up an external LED with a little dab of solder and  a couple header pins. (They could go on the top OR bottom - doesn't really matter)

    I stand corrected - thanks for clarifying!

    Question: how configurable is this thing via a modern Mac rather than a PC? How's it been going for everyone?

    Everything is configurable by popping the MacSD's SD card into your modern computer and editing the macsd.ini text file, so no difference.  An SD extension cable is highly recommended...

    Because they are essentially HD images. There was no official specification for ProDOS partitions on a CD-ROM, so its really just a raw dump onto the disc. There are Macintosh HFS CD-ROMs like this too (no ISO-9660 file system present on the disc). Apple later created the ISO-9660/HFS hybrid format to allow cross platform readable discs.



    Thanks for the explanation - makes sense now.


    If anyone else wants the IIgs CD "images", they'll be up on my server soon.

    I can read the Deluxe Ware .dmg image as an HD on my IIgs however.  It would be nice to have some other IIgs CD images to test out, but I haven't been able to find them...

    I found a few more IIgs CD images and have the same issue.  The images won't mount as CD images but work fine if you mount them as HD images.  So I guess that's one workaround...

  11. The modern .dsk format is different than the Disk Copy format I believe.  Your Color Classic should be able to read ProDOS formatted disks, and you could transfer files between the two computers that way.


    The easiest way would be to get a Floppy Emu - it will work with your Macs and Apple IIc+ so you could easily justify the cost!  They're so handy that I have two of them.


    Also, ADT Pro allows you to transfer disk images between a modern computer and your IIc+ with a serial cable.

    GS/OS can read ISO9660 discs provided the HS.FST is installed. If using Apple's SCSI cards, you need to install the SCSICD.Driver in addition to SCSI.Manager and SCSIHD.Manager.

    I'm using a GGLabs A2SCSI which is an Apple SCSI rev. C card clone, and I've got all three of those drivers installed.   HS.FST and HFS.FST are installed too.  The Deluxe Ware CD .iso image works fine on my Mac LC III but not on the IIgs for some reason.  I can read the Deluxe Ware .dmg image as an HD on my IIgs however.  It would be nice to have some other IIgs CD images to test out, but I haven't been able to find them...

  13. I love anything with the old Apple logo on it, so when I found a cheap dead Apple HD 20SC on eBay, I had to have it.  And I'd been looking for something to put my MacSD in, thinking that this would be better as an external device so I could use it with both vintage Macs and Apple IIgs.


    I had never retro-brighted anything before, but I found this premixed Retro-Brite gel which just applies with a paintbrush.  I kept it outside all day in the autumn MN sun, applying new coats every couple of hours, and after only one day it looked great!  Here's the before and after.





    After removing the giant 5.25" dead HD, the MacSD screwed right in with the included 3D printed bracket.  I hooked up a 20mA ultra bright green LED to the corresponding pins of the Expansion Port with some jumper wires for the drive activity light.  An SD extension cable runs out of the bottom of the case since you need access to the SD card in order to add CDROM images etc.  And because the MacSD needs no external power, the power supply is really just there for weight and if you get nostalgic to hear the fan running.




    Everything works well with my vintage Macs, and I've been able to get it to mount some 32MB ProDOS HD images on my IIgs, but I haven't been able to get a CDROM image working with the IIgs yet.  The IIgs recognizes that a CDROM is connected, but it can't read the CD.  However, I've only been able to test the Deluxe Ware CDROM image from Brutal Deluxe since I can't find any other IIgs CD images...

    Just unloaded.... A lot to go through, the boxes are filled with cards, ram, motherboards, parts, disks, everything. Will do a quick stock tonight. Got from a dealer/collector who is no longer interested.

    Are the two monitors on top of each other IIgs or Mac monitors?

  15. So my TDK 614-0003 power supply in my LC III recently died.  It was making a clicking sound and only putting out a few volts.  After recapping it, it's making good voltage but still making a clicking sound and the voltage goes up and down with these clicks.  Any idea what I should replace next?  I do have the mAcTX LC conversion kit but I was hoping to get the old power supply working to use as a backup.
