Mac Forum / General / Hardware / September 2007

I recently consolidated my old Mac stuff, and it was made easier by
coming upon a "modern" Mac, the Powermac 6400.  Unlike the other
Macs I had around, it used an IDE drive as a default.  So once
I consolidated various scsi drives and floppy disks to that
drive, I merely took it out, moved it over to my Pentium, and
copied it out that way.  I didn't have to get anything, unlike
connecting an SCSI drive to the Pentium which would require that
I buy an scsi card for it.

I presume the 7200 is recent enough that it uses an IDE drive
too, and thus this is likely the easiest route.

The 7100 is a first-generation PowerMac -- essentially a Quadra 650 with
a PowerPC processor. It uses NuBus (and PDS) rather than PCI, and SCSI
instead of IDE. Expansion cards for NuBus Macs were hard to find even
ten years ago. At this point, you'd have better luck finding an old SCSI
CD burner.

If you provide some details, you might get help with networking the 7100
in comp.sys.mac.comm.

The 7100 has an AAUI ethernet port.  Modern computers use RJ45/10base-T.  
You can use an AAUI to RJ45/10Base-T transceiver to network the 7100 to
newer computers.  They cost around $30 new.  I did a quick search and
found a couple of dealers who have them:

<http://www.welovemacs.com/pn512b.html>
<http://www.macsense.com/product/transceiver/LeeNet.html>

You might also be able to find used AAUI transceivers on eBay.  Just
make sure it says AAUI (or Apple AUI) and either RJ45 or 10base-T, not
10base-2.

I don't remember whether Windows NT includes support for Apple
file-sharing.  If it doesn't, you may have to set up FTP server software
on one computer and use an FTP client on the other to transfer files.

What kinds of files are you hoping to transfer?  Windows-compatible file
types, like JPEGs and TXT files and DOC files (Word documents), can be
transferred to PCs without difficulty.  Mac applications and many
Mac-specific files will have a resource fork which would be discarded if
you copy the files to a PC, rendering those files useless.

I used a Zip SCSI to pull data, and a Zip USB to read data into my new
machine.

A friend used an external CDR to move his files.

If you have a computer with a SCSI bus you can boot the
7100 in SCSI disk mode and read the data off the disk directly.
It takes a special SCSI cable,HDI-30 SCSI disk adapter cable,
or there were SCSI adapters and cables that could switch
between normal and target disk mode. Actually, it seems that
all you have to do is switch the state of pin 1, (ground/open)

and

Since the normal cable, the HDI-30 SCSI System Cable, had
29 pins, I'm betting grounding pin one signal's SCSI disk
mode. Check Google

Of course, your master will have to be able to read a HFS
disk which Microsoft probably won't do without a third party
solution. Now, if you have another Mac that will read
a SCSI bus and make a stable ethernet connection...
