DEC RX02 to MSDOS Conversion

I need to port files stored on a 8 inch DEC RX02 formatted floppy disc to a MSDOS formatted 3.5 inch floppy disc.

The equipment we have are a RX02 floppy disc drive and a VAX 4000 model 100 desktop computer.

How could we get the files stored on the 8 inch floppy to the VAX 4000 hard drive so we can FTP the files from the VAX 4000 computer to a PC.

Would this solution work or do you have another suggestion?

Thanks for your help.

Re: DEC RX02 to MSDOS Conversion

Give the old EXCHANGE utility a try.

$ HELP EXCHANGE

Depending upon the format of the diskette it might be as simple as the following (it's been a long time since I've used EXCHANGE so my memory might be faulty here).

$ MOUNT/FOREIGN DYA0:
EXCHANGE> COPY DYA0:*.* []
EXCHANGE> EXIT

Are they connected somehow? (How? I don't
know what the interface on an RX02 is, but
I wouldn't expect a VAX 4000-100 to have one
of them, whatever it is. Now, if you had a
Q-bus box on the VAX, and the right card in
that, my expectations could change.)

Hard to say, with the info available.

Assuming that you can get the giant floppy
drive connected/configured somewhere, the
next mystery might be how the data were
written to the floppies. If they were
written by/on an old VMS system, there might
be more hope than if they were written on,
say, an old Apollo workstation (which is the
last place I saw an 8-inch floppy spun in
anger). Reading the raw bits should be
possible almost anywhere, but recovering the
original structure could be harder.

There are whole businesses devoted to doing
jobs like this, if the bits are _really_
valuable.

There should of course have been an EXCHANGE command after the mount in my previous post.

$ EXCHANGE

My old MODULE.FAQ says:

M8029 RXV21 Q RX02 floppy disk drive control module


Or, if you had a SCSI 8-inch floppy drive, ...

Re: DEC RX02 to MSDOS Conversion


"DEC RX02 formatted": the chances are high they are from RSTS or RSX, then they are ODS1 and can be mounted as VMS volumes, and no /foreign and EXCHANGE is needed.
JUST MOUNT and COPY.
