    Bootable SC20 with IBM disk

    I used version 3.0.1. I just installed OS7.1 on the hard disk from a set of 10 floppies. Still can't boot. How do I tell if the system folder is "blessed"? -- maz

    .dsk raw floppy format?

    Appreciate the confusion. I don't mean mounting on the vintage mac. I mean mounting an image on a modern mac. I can read and write from and to using Floppy Emu through to the disk images on the sd card, but I am looking for an easy way to move vintage files to and from those disk images (on the sd card or other modern media). When I say "easy" I mean a piece of software to do the transfer rather than going through Windows, Linux, emulators, etc. Maybe XMODEM or KERMIT ends up being easiest though. -- maz

    Bootable SC20 with IBM disk

    Yeah, but I can both read and write once I've booted from a floppy. It's not a hardware/formatting issue. I am pretty sure I need a special driver to boot of the drive as it's a nonstandard 80MB IBM disk and not a 20MB miniscribe as I gather was shipped in the original 20SC. How do you guys boot from a SCSI device configured like this? -- maz

    Bootable SC20 with IBM disk

    Yeah, used both Lido 7 and the patched HDSC Setup (for non-Apple disks)... it still won't boot. I can read and write to and from fine after booting from a floppy.

    .dsk raw floppy format?

    Hi quorten, thanks for your reply. Couldn't get Executor to run, looks like an experimental/unsupported port from 10 years ago. I have been trying to mount those old disk images using standard tools (hdiutil, diskutil) - if it is an HFS volume inside, they can be mounted and read (not written) by hdiutil, however vintage 68k macs with OS6 can't read those volumes. I really want to avoid setting up a windows PC to move a file from the interwebs to my old mac. What software are you using on your vintage mac to transfer files over serial?

    .dsk raw floppy format?

    Hi cheesestraws, thanks for the answer. Spent a few hours now trying to get Basilisk to run without luck on my Mjoave machine. Without giving up on that just yet does anyone else use a simple tool to read/write *files* within a .dsk image (just as you would simply mount .img files)?

    .dsk raw floppy format?

    Hi forum, does anyone know how I might create, read, and write raw floppy .dsk files (as used by Floppy Emy) on a modern Mac? Alternatively, how do you transfer files from a modern mac to a vintage mac through an sd card with raw disk images? Thanks in advance! -- maz
  8. Hi all, I am trying to make an SC20 bootable connected to a Plus. It's had its old drive replaced by an 80Mb IBM drive at some point. I can read and write from and to the drive, but I can't boot from it. What am I doing wrong? Thanks! -- maz
  9. Hey forum, I've installed system 6 from the original disks onto a genuine SC20, everything works except I can't seem to boot from it. What's the trick? SCSI ID is 3. Thanks! -- maz
