I believe it's the same physical dimensions as a Xerox 2400? https://xeroxnostalgia.com/category/2400/ Don Resor N6KAW -----Original Message----- From: cctalk <cctalk-bounces at classiccmp.org> On Behalf Of D.

I'm in the middle of imaging a set of 5 1/4" diskettes from 1988 containing the Interpress conformance test suite. My plan is to - convert the MS-DOS backup format images to files (trivial) - find interpress to postscript converter to print the files. - compare them to the reference pictures to verify I got them all. The third part is the hard one. I believe there was a document to go along with the images, so you could verify they printed as expected. I don't think I have that any more. I'm looking for pointers to an online copy. My search has come up empty. Of course, the alternative is if someone has an interpress printer. We could just print them. Perhaps Curious Marc has one alongside the Alto?

I did not say it was.... The Dover was a SLOT (Scanned Laser Output Terminal) using the EARS protocol (Ethernet, Alto, Research character generator, Scanned laser output terminal). The Dover Laser Printer however was used with the Xerox Alto. Was the 9700 the first Xerox Interpress Laser printer, I don't know.
