![]() ![]() The machine now works just fine on a 256MB SD card running as the SCSI hard drive and 4MB of memory: Using Amigakit’s SCSI2SD adapter, I was able to remove the dead 20MB SCSI hard drive and emulate it using a micro-SD card. Below is a photo of the machine, complete with keyboard and mouse, running MacWrite: The machine could not power on at first, but after cleaning up the motherboard, reseating all socketed chips, and replacing the RAM with using spare SIMM modules from my junk box, the machine managed to boot up just fine. The authors of Mini vMac suggest getting System 6.0.8 software from Apple: You'll need Stuffit Expander to expand the SEA archives.Last week I found a vintage Macintosh SE that had long been hidden inside the store room of my apartment. Reformatting works in Snow Leopard, but Jaguar can't format floppies. Another workaround would be, once you've made the floppy, copy the program onto your hard drive, reformat the floppy to full size, then copy CopyRoms back onto the floppy. When I copied CopyRoms to the hard drive in my SE, it worked. I realized the problem was that when I used dd to copy the image to the floppy, it made a floppy with only a bit more capacity than the image, so there was no room for CopyRoms to place the rom file onto the disk. I had a problem, CopyRoms was not making a non-zero rom file in my SE FDHD. It would be best, instead of typing it, to copy and paste from the output of mount, and still double-check. disk1 in your case might be a hard drive or anything, so make sure to use the mount command first to find the right device. Make sure you don't type the wrong device. WARNING! If you put the wrong device at the end of that command, you could mess up your hard drive forever. Then go back to terminal and enter the following command, being sure to substitute your floppy device name for the last argument (mine was /dev/disk1, but yours may be different).ĭd bs=2x80x18b ( your floppy device name) But to access a drive at the base level, it needs to be unmounted (else a "device busy" error), so use Disk Utility to unmount the volume, but don't eject it. Since my floppy was called Unlabeled, I know this is it, so I use dd to copy the CopyRoms disk image to it. dev/disk1 on /Volumes/Unlabeled (local, nodev, nosuid) ![]() In my case, I type mount, and I see many lines, one line being First, you should insert a floppy in a connected drive, then in a terminal (shell), you should use the mount command to find out what the name of the floppy device is. One way to do it is to use dd in linux or OS X. Nowhere in the guides do authors tell you how to get the provided image onto a disk so you can put the disk in an old Mac and run CopyRoms. ![]() Instead of providing a program to copy onto a disk, the authors provide a raw disk image with the program on it. What is difficult to find is how to get a copy of CopyRoms running in an old mac. To run Mini VMac, you need a copy of ROMs from a 680x0 Mac, (from Mac 128, the original, to Mac II). You can get many variations here: CopyRoms For example, since I'm getting my ROMs from a Mac SE FDHD, I have to use version 24, compiled to match the capabilities of an SE FDHD, and to run on my (Intel) PowerBook Pro. ![]() You need to run a version of Mini vMac compiled to match the ROMs you use. Mini VMac allows users of newer Macs to run a Macintosh Plus in a window on their computer. ![]()
