      3 NetBSD/x68k _VER runs on the Sharp X68030 series PCs with TRUE
      4 MC68030 MPU (not MC68EC030) and FPU.  Since the processor of
      5 the X68030 series is MC68EC030, you need to replace it with
      6 MC68030 (Simply remove the old chip and put the new one instead.
      7 instead.  The largest difficulty might be to open your X68030).
      8 
      9 In addition, some accelerators are supported:
     10 
     11    Xellent30 series
     12    040turbo
     13    Jupiter-X (040 / 060)
     14    060turbo
     15 
     16 This means all models of X680x0 series PC except for CZ-600C
     17 and CZ-674C, by using the appropriate accelerator, can run NetBSD!!
     18 Note that the processor of Xellent30 series is MC68EC030, so
     19 you need to replace your processor as well as for X68030.
     20 
     21 The minimal configuration requires 4M of RAM and about 80M of
     22 disk space.  To install the entire system requires much more disk space,
     23 and to run X or compile the system, more RAM is recommended.
     24 
     25 Here is a table of recommended HD partition sizes for a full install:
     26 	partition:	advise,	with X,	needed,	with X
     27 	root (/)	20M	20M	15M	15M
     28 	user (/usr)	95M	125M	75M 	105M
     29 	swap		----- 2M for every M ram -----
     30 	local (/local)	up to you
     31 
     32 As you may note the recommended size of /usr is 20M greater than
     33 needed. This is to leave room for a kernel source and compile tree
     34 as you will probably want to compile your own kernel. (ALL is
     35 large and bulky to accommodate all people).
     36 
     37 Supported devices include:
     38     - Sharp genuine SCSI interface (builtin / optional)
     39 	* SCSI harddisks, CD-ROM drives, tape drives, scanners,...
     40     - Mankai Seisakusho Mach-2 SCSI interface
     41     - The builtin floppy drives
     42     - The builtin frame buffer (both of the text and graphics screen)
     43     - The builtin serial (RS-232C)
     44     - The builtin parallel (Centronics printer interface)
     45     - The standard keyboard
     46     - The mouse / trackball
     47     - NS16550 serial
     48     - Neptune-X ethernet
     49 
     50 Hopefully, the AD-PCM sound device will be supported on the next
     51 release.
     52 
     53 IMPORTANT NOTE: Xellent users *MUST* change the address map setting
     54 for it from the default ($ECC000 - $ECFFFF) before installation.  This
     55 is because the default address conflicts with the Neptune-X ethernet
     56 interface, and the Neptune driver is confused by it.  All the settings
     57 other than the default are ok.  Once you installed NetBSD, and configured
     58 your own kernel, you can restore the setting.
