I've been asked to refer a customer to someone with a 20MB 8" Bernoulli
setup. There are only 2 disks involved and absolutely nothing is known
of the provenance. I can put you in contact and you can name your terms
to do the work.
Note that a sector-by-sector image of the disks might be useful as it's
unknown if these are PC or Apple format.
Contact me off-list if interested. US only, please.
Thanks,
Chuck
