I actually find that *very* encouraging. I'm sure he'd allow a discount
for a "complete" set purchase rather than one-off copies.

The good thing is that he's not just hoarding the intellectual
property... he's willing to entertain the idea.

Does anyone have any evidence of average price for rainbow magazine
issues on Ebay? We should probably go to him with that kind of
information in hand, as well as the average lot sizes so you could
figure in what someone would really pay given shipping, etc. to get a
complete collection and then work down from there.

Plus he ought to see reason and allow some profit to the those doing the
work of getting it into digital form. That amount could be distributed
to the folks scanning the documents, or placed in a fund for programming
or hardware-design bounties, or something like that.

The DVD would have to be less... PDF copies are not nearly as valuable
as printed copies to a collector.

Just business. Once it's in distribution, he might allow playing with
the price to find the sweet spot for sales.

I dunno. DVD seems workable.

As to bit-rot: we could use a utility to add an error correcting code to
each file. And reserve space for, say, a 50meg "Damn Small Linux" mini
linux distribution so that the DVD can boot itself and make as many
backup copies as you need... just have to remember to make a new image
every few years. I think that would solve the bit-rot problem once and
for all, and would probably interest other vintage documentation

You can get about 13gig onto a Mini-DV tape w/ error correcting code
which can withstand a pin-sized hole in the tape.

But not everyone has mini-dv.

I'd be willing to sacrifice some of mine. That's what makes it good to
have a collective effort... everybody only has to donate a few of their
