3NetBSD/sun3 _VER runs on most Sun3 machines, including:
4		3/50, 3/60, 3/110
5		3/75, 3/150, 3/160
6		3/260, 3/280, 3/E
7
8NetBSD/sun3 _VER does not run on the Sun3/80 (sun3x class)
9but that is presently handled as a separate distribution.
10Use NetBSD/sun3x for Sun3/80 and Sun3/470 support.
11
12The minimal configuration requires 4M of RAM and about 80MB of disk
13space.  To install the entire system requires much more disk space
14(approx. 100MB additional space is necessary for full sources).
15To run X or compile the system, more RAM is recommended.  Good
16performance requires 8MB of RAM, or 16 MB when running the
17X Window System.
18
19Here is a table of recommended HD partition sizes for a full install:
20	partition:	advise,	with X,	needed,	with X
21	root (/)	20M	20M	15M	15M
22	user (/usr)	95M	125M	75M 	105M
23	swap		----- 2M for every M ram -----
24	local (/usr/local)	up to you
25
26As you may note the recommended size of /usr is 20M greater than
27needed. This is to leave room for a kernel source and compile tree as
28you will probably want to compile your own kernel. (GENERIC is large
29and bulky to accommodate all people).
30
31Note that the sun3 installation procedure uses a `miniroot' image
32which is placed into the swap area of the disk.  The swap partition
33must be at least as large as the miniroot image (8MB).
34
35The following Sun3 hardware is supported:
36
37	Serial ports (RS232):
38		built-in ttya, ttyb
39
40	Video adapters:
41		bwtwo, cgtwo, cgfour
42
43	Network interfaces:
44		On-board Lance Ethernet
45		On-board or VME Intel Ethernet
46		Sun3/E SCSI/Ethernet board
47
48	SCSI:  (Most SCSI disks, tapes, CD-ROMs, etc.)
49		On-board "si" (SCSI-3)
50		VME "si" (SCSI-3) board
51		Sun3/E SCSI/Ethernet board
52
53	SMD Disks:  (the big, heavy ones 8^)
54		Xylogics 450/451
55		Xylogics 753/7053
56
57	Input devices:
58		Sun keyboard and mouse
59
60	Miscellaneous:
61		Battery-backed real-time clock.

63If it's not on this list, there is no support for it in this release.
