I dont know anything specific, but you're probably referring to a
machine built with the "Tsunami" chip, which is basically a single
chip computer minus some of the I/O you need for a workstation (video,
etc). There is rumor that Sun is going to introduce a new low end
based on the chip, to be priced about the same as the current IPX.

The new high end is definitely more interesting, though....

NeWSprint 2.0 REQUIRES OpenWindows 3.0 in order to work correctly.  If you did
not load the mini OpenWindows from the NeWSprint CD, do it right after reading

Even if you are using OW 3.0, use the mini version on the NeWSprint CD, as it

Hi,

I've been trying to make a bootable floppy for my IPC without too
much success.  I'm waiting on the $$$ to be available to get a CD
ROM, so for the interim, I'm planning to back up to a drive on
another machine and have a disaster recovery floppy, if possible.

I used newfs(8) to put a viable file system on the floppy; no
problems there.  I did a cd to /usr/kvm/mdec and found a file
called bootfd.  I presume from the name that this must be the
installable boot image for a floppy?...  I tried:
./installboot -vlt /boot bootfd /dev/rfd0c.

It comes back with an error message similar to:
installboot: /boot file not present on target device /dev/rfd0c.

If I can get past this much, I'm wondering what I have to do
next?..

1.  make a small /dev with just enought devices?...

2.  copy over the "gneric" /vmunix from the SD drive?...

3.  a few things from /etc and /bin....?

...or is this as Benjamin Braddock said, "totally baked."

The numbering is only 1 to 1 if you use the following number schene, which
is not the numbering scheme used for labelling connectors.

Centronics connector:

1  3  5  7     49
           ...
2  4  6  8     50


DB-50 connector:

1   4   7       49
  3   6   ... 48
2   5   8       50

The nice thing about this numbering scheme is that if you can find IDC
connectors of each type you can just clamp one on each end of a 50 pin
ribbon cable.

It certainly will. I was disappointed with my IPC for a long time

I think this number is probably too high even as a maximum.  Thermochemical
BTU per hour converts to Watts as roughly
 ( X BTU/hr) * ( 0.292875 Watts hr /BTU) = (Y Watts)
Therefore, 11577 BTU/hr = 3391 Watts.  On a standard 110 V rms line this
machine would draw around 31 Amps.  I would say this is about 5 to 10 times 
too large.

In the process of trying to decide what to do, I was wondering
what the going rate is for a SS2 clone from the handful clone makers.
Is there a significant price difference?  Is it really a clone
performance-wise?  Is any one of them a particularly good deal?
Where do you buy these things, anyway?

Don't put up with it, because it's not worth the aggravation.  Check
out the prices at a good hardware repair shop.  If they have the right

replaced the Philips flyback with one of their own design, so you'll
avoid the "dark, smoking whine" symptom that everybody gets eventually

I recently inherited an enclosure containing a 1/4" tape drive and a
Micropolis 1355 disk drive.  Unfortunately, there was no documentation
with it.

I want to hook it up to a Sun 3/50 and use it as the boot disk.  I was
able to bring up MUNIX from a boot tape, and it saw the drive as sd2.
After formatting and partitioning the disk I tried copying the miniroot
to sd2b and kept getting "no device" errors.  When I do a dkinfo on the
sd2 device (from MUNIX) I get:

Micropolis MD21 @addr 140000 unit #8
 a: blah blah blah
 b: blah blah blah
 c: blah blah blah
 g: blah blah blah

The 'unit #8' doesn't look quite right to me.  I used '8' as the unit when
I copied miniroot to sd2b and things went fine.  I was able to install the
SunOS without errors.  But, when I tried rebooting (using sd(0,2,0) vmunix)
I get 'No Device' errors.

How can I make the system 'see' the drive at boot time, and I'd like to 
make the drive sd0 while I'm at it.  Anyone know the right jumpers to 'jump'
or 'unjump?'

"neutral is running quite high, which I gather is one symptom of harmonics.

if you have the option, and if it's really important to you, you might
consider wiring up a secure power net with a central ups, like hospitals do.
they use orange-colored outlets so that they are easily identifiable.
unless the building is really wiring-hostile (e.g. brick walls), it should be
a lot cheaper per-unit than individual upses.
