Help Installing 68k NetBSD on Mac II

loaded all binaries as instructed and upon booting it states

"You need a PMMU or a 68030 or above to run this"  "Orange Whip"

I have a MAC II with an 80MB HD, 2MB partitioned for MAC o/S, the rest an
A/UX partition.  Does that mean I can't run NetBSD on this machine? or am
I doing something wrong?

Any and all comments appreciated.

You can run NetBSD on a MacII, but you will need to get a pmmu(not very
expensive) and plug it in where the mmu is now. Then it will work fine!

You are doing nothing wrong except overlooking the error message and the
hardware requirements...  ;-)

The 68020 has no inherent facilities for paged memory management.
NetBSD needs to have a PMMU (68851) with the 68020.  The 68030 and
68040 have that functionality built-in (in slightly different ways).

So, you need to pick up a PMMU to replace the HMMU that Apple has
filling the slot, or you need to get a 68030 upgrade (an accelerator
(which may not work under NetBSD--some successes have been noted)
or a IIx upgrade (which will also give you the 1.4MB floppy support
on the motherboard and ROMs that will allow you to use more memory,
I think)).

   Where does all my time go?  <a href="http://www.netbsd.org/">Guess.</a>

 
 
 

1. NetBSD 68k - Mac Classic II

Okay, I've been searching around for a good machine to set up as a server
for two dumb terminals (one Wyse WY-85 and a Vision VT-202 terminal). I have
stumbled on to a Mac Classic II, which is a 68030 system. The FAQ lists this
computer as not supported because the internal video is not working right,
and that it would only be able to function with a serial connected terminal.
Ideal for my purposes. My problem is locating a Mac Serial (Mini DIN 8) to
RS 232 Serial (DB25) connector. I could make one, but I can't find a
definitive answer to what steps need to be taken to ensure a fast (The
terminals go to 33600 bps hardware flow control) connection between the two.
Does anyone have an idea of a) where to get the schematics for the cable, or
a cheap cable premade, and b) how to set up NetBSD for terminal access
without any means of direct access?

THanks in advance,
Zen
