Help with advice to get Mac Plus running

I have a Mac Plus -- I have 3 working/booting floppies, one disk tools disk, one pre-6 disc & macpascal disk with system 5.. I have additionally a 30Mb external scsi, & zip drive with 2 zip disks.

I tried formatting the 30mb NON-Apple ROM scsi as a Macintosh Volume with my NeXT computer (only machine I have with a scsi interface other than the mac). It formats it fine, I can copy files to the drive. recognizes on the NeXT as a mac volume, but Mac Plus with disk tools doesn't mount the drive.

I tried making a system bootable 7 image on my macbook pro with Basilisk emulator, then transfer to the NeXT and copy the image to the HD, which also works, the NeXT sees all the system files and everything on the drive, Mac Plus still doesn't care. Doesn't see it.

I think there is some kind of Apple SCSI driver which is probably not added to the drive boot sector when I use the NeXT to format the disc. Anyhow, I tried also formatting zip drives, the mac plus locks up when i boot it with a zip disk formatted with the NeXT in the drive. it boots normally if there is no zip disk in, but still it will not mount the disk.

I have all the software in the world in files and so on, on my modern mac.. but I have no freaking way of making a floppy or moving any data to the plus. I would like to even be able to probe the scsi bus to see - but stupid Apple HD setup only checks on apple rom'd drives so it doesnt help a bit. I am at wit's end..

maybe if someone could create a disk image of a HD or zip on which there are the proper drivers, I imagine if they created a dd image or something of the scsi drive and then I could write it out to my zip drive or HD maybe the mac would recognize it? I don't know what to do. I wish now I didn't throw out my old powerbooks and other beige equipment that had a superdrive.

HELP!!!

What can I do? a thousand thanks

That's really the key here.... You need a patched copy of HD SC Setup on your Plus. With the patch, it no longer checks for the Apple ROM and will accept to format any accessible drive. In fact it will even format a Zip disk as though it were a hard drive!

Now, the challenge will be getting it onto the Plus in the first place.... A Mac with a superdrive would be a huge help. Given what you've got to work with I'm not sure what to suggest. :-/

Thank you so much for your reply. I think the next step is to find another vintage mac with a superdrive. I was hoping for miracle to appear, but I can't see of any other way either.. :-(

Something like a late model SE with an ethernet card would do wonders. Could actually do everything on the SE, then transfer the formatted and system software equipped drive to the Plus. Just have to make sure that the SCSI ID isn't set to 0 when the drive is connected to the SE.
