Hi, all.

I updated 'distrib/notes/pmax/hardware' file.  I made several
typographical and tracemark justifications leaving its contents almost
untouched.  Here is my thought;

- Following statements are relevant enough, or need updated (in
figure-wise)? 

> The minimal configuration requires 8M of RAM and ~60M of disk space.
> To install the entire system requires much more disk space, and to run
> X or compile the system, more RAM is recommended.  (NetBSD with 8M of

- DECsystem 5900 is not mentioned here.  NetBSD/pmax will recognize it
as DECstation 5000/2{4,6}0 if tried, and should run flawlessly (I
don't TcE TURBOchannel Extender thing will work).  Oh, Simon, I think
I found the way to distinguish DECsystem 5900 from 2{4,6}0.

It's regretful we can not include DETFA TURBOchannel FDDI option card
to a supported device list.

NetBSD/pmax _VER runs on the following classes of machines:
	- DECstation 2100 and 3100, also known as "pmin" and  "pmax" 
	- Personal DECstations (5000/20, and /25) also known as "MAXINE"
	- DECstation 5000/120, /125, and /133, also known as "3MIN"
	- DECstation 5000/200, also known as "3MAX"
	- DECstation 5000/240, also known as "3MAXPLUS"
	- DECstation 5000/50, 5000/150 and 5000/260 - R4000 and R4400
		variants of the the MAXINE, 3MIN and 3MAXPLUS

NetBSD/pmax _VER does *not* (yet) run on these machines:
	- DECsystem 5100 (an R3000-based cousin of the DECstation 3100)
	- DECsystem 5400 and 5500 (Q-bus based systems, similar to a VAX
		'Mayfair' and 'Mayfair II', but with an R2000A or R3000
		CPU instead of a CVAX CPU.)
	- DECsystem 5800 (VAXBI based multiprocessor, a VAX 6200 with
		VAX CPU boards replaced with MIPS CPU boards)

The minimal configuration requires 8M of RAM and ~60M of disk space.
To install the entire system requires much more disk space, and to run
X or compile the system, more RAM is recommended.  (NetBSD with 8M of
RAM feels like ULTRIX with 8M of RAM.)  Note that until you have
around 16M of RAM, getting more RAM is more important than getting a
faster CPU.

Supported devices include:
	DECstation 2100 and 3100 baseboard video: 
		one-bit mono or 8-bit pseudocolor 1024x864 framebuffers.

	DECstation 5000 series TURBOchannel video:
		PMAG-BA	1280x1024 8-bit color framebuffer,
		PMAG-AA 1280x1024 monochrome framebuffer,
		PMAGB-BA 1280x1024 8-bit color framebuffer,
		PMAG-DV Personal DECstation baseboard 1024x768 framebuffer.

		NOTE:  All supported DECstation video produces sync-on-green.
		Be sure to use either a DEC-compatible fixed-sync monitor
		or a multisync monitor that supports sync-on-green.

	serial ports: 
		ttya and ttyb (can be used as console if needed).

	ethernet: 
		on-board AMD LANCE ethernet, 
		TURBOchannel AMD LANCE ethernet cards (the "PMAD").

	SCSI: 
		on-board DEC SCSI controller (2100 and 3100),
		on-board NCR SCSI controller (5000 series machines),
		TURBOchannel NCR SCSI controller (the "PMAZ").

	DEC (LK-201 or compatible) keyboard.
	DEC ("hockey puck" or compatible) mouse.


Hardware the we do NOT currently support, but get questions about from
time to time:
	DECsystem 5100, 5400, 5500 and 5800 machines
	Prestoserve NVRAM on DECstation 5100 and 5000/2xx machines 
	audio drivers for Personal DECstation machines
	floppy driver for Personal DECstation machines
	TURBOchannel audio hardware (LoFi)
	PMAG-C 2D accelerated framebuffers with onboard i860 processors

	NOTE: the primary obstacle to support of all but the very
	last item is non-availability of sample hardware for development.

	The primary obstacle for the i860-based framebuffers is that there
	is no documentation on the accelerator board.
