3NetBSD/pmax _VER runs on the following classes of machines:
4	- Decstation 2100 and 3100, also known as "pmin" and  "pmax" 
5	- Personal Decstations (5000/20, and /25) also known as "MAXINE"
6	- Decstation 5000/120, /125, and /133, also known as "3MIN"
7	- Decstation 5000/200, also known as "3MAX"
8	- Decstation 5000/240, als known as "3MAXPLUS"
9	- Decstation 5000/50, 5000/150 and 5000/260 - R4000 and R4400
10		variants of the the MAXINE, 3MIN and 3MAXPLUS
11
12NetBSD/pmax _VER does *not* (yet) run on these machines:
13	- Decstation 5100 (an r3000-based cousin of the Decstation 3100)
14	- Decsystem 5400 and 5500 (Qbus-based systems, similar to a Vax
15		'Mayfair' and 'Mayfair II', but with an r2000a or r3000
16		cpu instead of a CVAX cpu.)
17	- Decsystem 5800 (xbi-based multiprocessor, a Vax 6200 with
18		 Vax CPU boards replaced with Mips cpu boards)
19
20The minimal configuration requires 8M of RAM and ~60M of disk space.
21To install the entire system requires much more disk space, and to run
22X or compile the system, more RAM is recommended.  (NetBSD with 8M of
23RAM feels like Ultrix with 8M of RAM.) Note that until you have
24around 16M of RAM, getting more RAM is more important than getting a
25faster CPU.

27Supported devices include:
28	Decstation 2100 and 3100 baseboard video: 
29		pm one-bit mono or 8-bit pseudocolour fraem buffers.
30
31	Decstation 5000 series TurboChannel video:
32		PMAG-DV Personal Decstation baseboard 1024x768 frame buffer.
33		PMAG-BA	1024x768 8-bit colour frame buffer.
34		PMAGB-BA  1024x768 8-bit colour frame buffer.
35		PMAG-AA  1280x1024 four-bit greyscale frame buffer.
36
37		NOTE:  All supported DECstation video produces sync-on-green.
38		Be sure to use either a DEC-compatible fixed-sync monitor
39		or a multisync monitor that supports sync-on-green.
40
41	serial ports: 
42		ttya and ttyb (can be used as console if needed)
43
44	ethernet: 
45		on-board AMD Lance ethernet ("le0"), 
46		TURBOchannel AMD Lance ethernet cards (the "PMAD").
47
48	SCSI: 
49		on-board DEC "sii" SCSI controller (2100 and 3100)
50		on-board "asc" SCSI controller (5000 series machines)
51		TurboChannel "asc" SCSI controller (the "PMAZ").
52
53	DEC (LK-201 or compatible) keyboard 
54	DEC ("hockey puck" or compatible) mouse.

57Hardware the we do NOT currently support, but get questions
58about from time to time:
59	Q-bus Decsystem machines
60	Decstation 5100 machines
61	PrestoServe NVRAM on Decstation 5100 and 5000/2xx machines
62	audio drivers for Personal Decstation machines
63	floppy driver for Personal Decstation machines
64	TurboChannel audio hardware (LoFi)
65	PMAG-C 2-D accelerated framebuffers with onboard i860 processors
66
67	NOTE: the primary obstacle to support  of all but the very
68	last item is non-availability of sample hardware for development.
69
70	The primary obstacle for the i860-based framebuffers is that there
71	is no documentation on the accelerator board.
