They are already .dsk files. I consider myself somewhat of an expert
regarding disk image creation. :) I'll send them to you at my next
opproutinity.

I suggest adding a column to your magazine web page to indicate which
disk/tape images you have access to. Since the disks are flippy I have
dumped each side to it's own file. Since there is no copy-protection on
these images, straight sector dumps are perfectly suitable and will work
with all of the emulators/tools.

An interesting note. The disks usually have an RS-DOS side and an OS-9
side. But if the RS-DOS files were too numerous for one side of the
disk, the second side would be dual foramtted with a RS-DOS patition and
an OS-9 partition. Pretty nifty.

Regarding the tapes. I don't have any but hopefully a complete set could
be found and included in the project.

WAV files of each tape could be _very_ large. The minimum sampling rate
would be 4800 hertz, that would reduce the file size dramatically. But
be wary of using popular lossy compression (mp3), that could destroy the
data. I do remember reports of people saying they didn't have any
problems with mp3 compressed tape files. But I think it would be worth
looking into some of the free lossless (flac) audio compression.

Of course another option is to not include disk/tape images, but to rip
the files out of the image and just store them as indivdual files. This
will dramitically reduce the space needed to sotre this data, but I
don't think it would be worth it to loose all of the meta-data
associated with each file.

Each disk/tape came with a flyer describing what is on each disk/tape. I
have not scanned my flyers yet, but I will. I suggest adding another
column to determine if the scan of the flyer has been generated.
