UWS 4.2 announcments

archerb@kuhub.cc.ukans.edu (05/02/91)

  Two quick things on the new DEC RISC & Ultrix announcments.  From the
preliminary info on the DECstation 2000/120(125) platforms it appears that
some or all of the 3100 motherboard is retained.  We'd be interested in
the new models, *if* the ethernet controller used were the same as the
5000/200 (not the 2100/3100 controller).  Anyone seen anything on this?

  Also, the Ultrix 4.2 announcement mentions again OSF/Motif (as does the
DECstation 5000/120(125) announcement).  Is this still refering to the
license again, or is OSF/Motif finally being included?  If not, I wish
DEC would just drop DECwindows and include Motif - or give us the option.
Believe it or not, some of our bosses do *not* see the point in purchasing
a developer's kit for the window manager...when it is suppose to be coming
sometime anyway.  Oh, well....

         Thanks to Harold at York University (my folks are from London, Ont.)
and Al Casamento at DEC for the answers on disk partitions. :-)

None of the motherboard for the 3100/2100 is retained.  The new
product is a complete redesign that could best be described as a
"minimization" of the DS5000/200.  On the ethernet controller, this is
from the technical overview of the new DS5000/100:


	Ethernet Connect

	A ThickWire Ethernet controller with a 15-pin DSUB connector is
	implemented via a LANCE (Local Area Network Controller for
	Ethernet) chip. The I/O control ASIC supports DMA transactions
	for the LANCE, which manages transmission and reception of
	packets via a dedicated buffer in main memory.

	To connect a DS 5000/100 Series workstation to a ThinWire
	Ethernet network, a Digital ThinWire Ethernet Station Adapter
	(DESTA) is used in conjunction with a ThinWire Ethernet
	(T-connector), a ThinWire Ethernet terminator, and a
	ThickWire-to-DESTA transceiver cable.  To connect the DS
	5000/100 Series to twisted pair, a commercially-available
	twisted-pair-to-ThickWire adapter may be used.

	An optional ThickWire Ethernet controller is available on a
	single-width TURBOchannel option card.

I believe this is the same chip used in the DS5000/200 (the LANCE
chip) although I know that DMA is new.  The ASIC doing the DMA was
developed in conjunction with this product.
