Hey folks,
somewhere out there is sitting a unit called CR10. It's huge and I want to save it
from scrap.
Does anyone know if there's a difference between a CR10 and CR11? I have a CR11 Unibus
interface...
Perhaps I could make them working together?
Is anyone desperately looking for such a thing? In that case.... Located in northern
Germany.
Best wishes,
Philipp

Oh, *I* am desperately looking for such a thing. No way I could
afford to ship from Germany though! *sob*

The CR-10 is a card reader designed for the PDP-10 I/O bus and requires a BA-10
controller. It's a 36-bit device and won't fit on any PDP-11 bus.

If it comes with a BA-10, let me know.

Looking at the CR10A and CR10B the ratio of CPM to power Hz is about
the same. Does this mean that those of us who had cards read in 50Hz
countries were being ripped off :-)

Well it does take time to convert cards from 60Hz to 50Hz...
Now if you bought 50Hz cards in the first place ...
