	Probably, but the DECstation is still a workstation.  You
	probably don't want the extra graphics hardware and certainly
	don't want to run any of the windowing software.

	I don't think we offer the 2100 in a DECsystem version.
	Still if the monochrome, smallest monitor 2100 costs
	less than a DECsystem 3100 then you can probably find
	a way to turn it into a DECsystem.

	Also check the prices of the 5100.  I would expect that
	they are higher then the 2100/3100, but maybe not.

> 2) Is 8MB enough memory?

	Probably not.  I have access to a DECsystem 3100 running
	V3.1D and just sitting pretty idle it's using about 10 MB
	of memory.  Hopefully we'll fix that problem someday...

	ULTRIX without the workstation stuff (DECwindows, X, etc)
	should comfortably fit onto two RZ24's.  I don't know if
	this is a supported configuration though.  The installation
	can get real hard if you don't have what the installation
	scripts think is a supported configuration.
