- This is likely correct, except the hardware is a called a Spur Adapter and
- is sold by Xerox. It converts a Centronics parallel interface to an IBM
- channel interface (this interface may well be the last pair of buss and tag
- cables left in our shop!). It of course costs the moon (around $10,000 as I
- recall), but then so did the printer so that shouldn't be a problem.
- As I recall a 9700 does better than 100 pages a minite (its smaller
- brother, the 4090, that we have does 92 pages a minite) so it needs a little
- more data than 38k (a channel will drive it at about 1 megabyte / sec), a VAX
- running over ethernet through a terminal server into a Centronics port (because
- the VAX Dataproducts interface we have is slow) will drive it reasonably hard.
- This may be an option for you it the Pyramid DataPoducts is too slow (I know
- nothing of Pyramids so there may be no problem). Now if the Spur just let
- you execute arbitrary channel programs so we could get mainframe 3420s and
- 3480's onto an ethernet ...
