Yes, we need to be able to access the files.
I?m going to see if my old 486 will still boot up, I know I used to use it with imaging
RX50 floppies. I?m not an x86 collector, so have a pretty limited selection of PC
Hardware. I?m on my Sabbatical right now, so this request came in at a good time. Though
first I have to finish up on some VAX and Alpha systems I?m working on, so as to free up
space. That or finish a cleaning project in my office. :-) The cleaning project is needed
to finish the VAX/Alpha projects?
Is there any chances of reading these with Commodore 128 running CP/M, or a Kaypro 2? The
Kaypro is definitely on my ?project list?, it worked last time I played with it. I
*might* have a DEC Rainbow, or I might have given it away. If I do, I have no idea of its
condition. An Apple //e would be another old system with 5.25? drives, but seems more
unlikely. I might still have an old Kaypro PC, though it hasn?t been used since ?94 (and
there is a good chance it went to LCM).
My focus is DEC and Commodore, though I do have a lot of Apple // gear.

Imagedisk is great for making images.
BUT, the original request is not for images, it is for the previous owned wanting access
to be able to use the content of the FILES that are in those images.
