Quite a hack! So you copy in real time as it were? Direct from packs on a
running Alto to packs on a running 11? Would it be practical to hack it
further to capture the data to an image file so anyone with an 11 / RK
combo could write packs?
I have 6085s and Stars; I'd love an Alto to round out the collection - but
not at $40k! Crazy prices these days; I've never paid more than a couple of
grand for anything - and usually a lot less.

Me too, but I think I'll just have to dream about it. I've been working on a
project though...

No, I copy from an image file on the 2.11BSD filesystem on the 11 to a
disk pack on the Alto -- the Alto's disk controller and Diablo drive do all

I meant Cardcage / internal pictures which I know more than a few people on
this list have asked for...
