hardware revision 1.1 
1
2NetBSD/sun3 1.1 runs on most Sun3 machines, including:
3		3/50, 3/60, 3/110
4		3/75, 3/150, 3/160
5		3/260, 3/280
6
7NetBSD/sun3 1.1 does not run on the Sun3/80 (sun3x class)
8because the sun3x MMU and other devices are very different.
9
10The minimal configuration requires 4M of RAM and ~80MB of disk space.
11To install the entire system requires much more disk space (approx.
12100MB additional space is necessary for full sources).  To run X
13or compile the system, more RAM is recommended.  Good performance
14requires 8MB of RAM, or 16 MB when running the X Window System.
15
16The following Sun3 hardware is supported:
17
18	Serial ports (RS232):
19		built-in ttya, ttyb
20
21	Video adapters:
22		bwtwo, cgtwo, cgfour
23
24	Network interfaces:
25		On-board Lance Ethernet (le)
26		On-board or VME Intel Ethernet (ie)
27
28	SCSI:  (Most SCSI disks, tapes, CD-ROMs, etc.)
29		On-board "si" (SCSI-3)  [Note 1]
30		VME "si" (SCSI-3) board [Note 1]
31
32	SMD Disks:  (the big, heavy ones 8^)
33		Xylogics 450/451  [Note 2]
34		Xylogics 753/7053 [Note 2]
35
36	Input devices:
37		Sun keyboard and mouse
38
39	Miscellaneous:
40		Battery-backed real-time clock.
41
42Note 1:
43    The "si" driver now supports DMA and disconnect/reselect
44    but due to the imaturity of the DMA code, those features
45    are disabled by default.  To enable DMA (and get faster
46    SCSI performance) patch the variable si_options in the
47    file /usr/src/sys/arch/sun3/dev/ncr_si.c as indicated.
48
49Note 2:
50    SMD disk support is almost ready, but could not be tested
51    in time for this release.  Drivers are provided for the
52    Xylogics 450/451 and Xylogics 753/7053 VME boards only as
53    source code.  They compile but have never touched a disk.
54
55If it's not on this list, there is no support for it in this release.
