Subject: Trouble installing internal drive in mono station
Reply-To: rolfe@ldp.com

Is there some secret to installing a drive internally in a Station?

Yesterday I took an external Maxtor LXT-340 (originally used with a Mac) that  
wasn't in use and decided it would be a good guinea pig for a 3.0 install.   
My intention was that after installing 3.0, I'd swap it with the Quantum 105  
internal on a recently acquired (used) Station.

The 3.0 installation proceeded smoothly (i.e. the system recognized the  
drive, etc.) and terminated normally.

However, when I swapped the drive into the Station, *nothing * I did could  
get it to even see that it was there (i.e. it wasn't seeing it on the bus.)
I'd get "boot device not found" errors every time.  Now, I of course  
installed the termination resistors (got the polarity right too) and jumpered  
the correct pins for SCSI address 1 and I also tried 0.

No difference.

After several hours of frustration, I swapped the Quantum back, and  
reinstalled the Maxtor in the external case (taking out the termination  
resistors) and everything worked normally.

Anyone have any bright ideas on this one?

So it would seem, therefore, that if all the old NeXT machine owners want ADB  
support, they must purchase a Turbo machine or is there some way for cube  
owners to trade in their old CPU board for a discount on a Turbo board?  Is  
buying a Turbo board possible (just the board for the cube, not the cube shell  
itself)?  If so, how much is list price on that?

Thanks.

Greets to all you folks out in netland.

I recently bought a used mono 25MHz cube, and am having problems with the DSP 
port.  I'm running System 2.1, and the cube is an 040.

Specifically, my problem is this - my DSP seems to be broken.  No kidding :(

For instance, when double-clicking on a score for ScorePlayer to play the 
music, a dialog pops up that says: "Can't open DSP.  Perhaps another 
application has it."  Hmm.  But I know no other application is running.

When I go to turn on the sound in Boink Out, I got this nifty dialog that says 
"Can't open the DSP."

I'm at my wits end. :(  I know I'll be flamed for this, but I never had this 
problem on my Indigo. ::::ducking::::

If anybody has a remedy to this problem, please email it to me or post it to 
this newsgroup, or get in touch with me.  Thanks.

I just checked the man page (NeXTSTEP 3.0.1) and it seems that compression
is on by default. Now, regarding the number of buffers...I have 32 Meg of
RAM in my 25MHz slab but the thing still churns like crazy when task 
switching.  What do I put in my (I assume) /etc/rc.local to increase
the number of buffers?

What kind of circuit do you need to connect a line-level source 
(like the RCA connectors on a CD player) into the microphone jack
of the sound box?  Does the connector allow stereo input?  Guess I
should have taken that EE101 class...

    Yes, check to make sure that the Supra is asserting CTS, both in
    command mode and when carrier is detected.	Also make sure that the
    Supra drops carrier when DTR goes away (and asserts CTS).

    The problem is that /dev/cuf* requires CTS to be asserted (positive
    voltage) not only to be able to send data, but also apparently in order
    to disconnect.

    The similar situation I was in:  I was TIPing to some hardware I'm
    working on (that has a serial port) and the DIN->DB9 converter wasn't
    passing CTS back.  When I manually wired CTS I was able to disconnect.
    Note that my cable was setup to loopback the NeXT's DTR into it's DCD,
    thus simulating a modem.

>(polling is cheating)

    DSP chips are designed to handle real-time operations.  It's kinda
    useless using an 040 for this when you cannot guarentee the interrupt
    latency (and the fastest an 040 can take an interrupt is too slow
    anyway).

    DSP chips generally have very specialized interrupt hardware.  An
    interrupt on the Analog devides ADSP or Motorola 5600[0/1] for example
    fetches two instructions and INSERTS them into the instruction pipeline
    (this is known as a short interrupt).  If one of the instructions is a
    JSR then the mechanism extends into a long interrupt.

    The overhead for any DSP interrupt that utilizes the quick mechanism is
    ZERO, the minimum processing time for such interrupts being 2 cycles
    (to run the two instructions).  The overhead for a long DSP interrupt
    is generally on the order of 2 cycles (the JSR).  The interrupt
    latency, baring interrupts being disabled, is the 2 or 3 cycles it
    takes to get to the inserted instructions in the pipeline... not wasted
    either since the DSP is still executing main line code for those 2 or 3
    cycles.

    Interrupts on DSP chips can be FASTER then polling.

    This is why even a 4 MHz DSP can handle more real time IO then a 33 MHz
    040.

    Then it wouldn't be a DSP chip. <grin>

Please tell me how to make a Mac Floppy automount...


Todd,

in /usr/filesystems there should be a directory called mac.fs

Executor sometimes (usually) renames it to mac.fs.SAVE (or something
close to that) and put in another directory called macintosh.fs (or
something)...  to get mac floppies to mount, just remove the macintosh.fs 
dir and rename mac.fs.SAVE to mac.fs (you have to do this as su root)

this actually works, and I have not had any further problems mounting
Mac floppies after this.

Also, look at the people buying ND systems in bulk these days.  Typically,  
these are sites that demand live TV feeds in the corner of people displays

Thank you very much to everyone who replied to my article
<1992Sep15.033823.3503@cs.yale.edu>
Because a number of people requested I send copies of the responses, I 
decided to post a summary of what I learned:

1) Most mac drives do work on the NeXT, but because mac SCSI isn't
quite standard some do have problems. I did get a large number of 
responses from people who have been using mac drives of all shapes and
sizes without problems. In fact no one reported to me that they had
problems with mac drives. Just be sure you buy from someone who knows
NeXT hardware and has good support policies.

2) The NeXT does not actually use SCSI-2, so there is no performance
penalty when using a SCSI-1 drive with the NeXT. Some people suggested
that reformatting a mac drive using 1024k blocks would make mac drives
perform better with the NeXT, but I have no idea what this means.

Thanks again for all of the responses.

   connected?

2. Is it possible to connect different types of scsi harddrives NeXT at the
   same time? Some of the older Unix versions had some problems if drives were
   different.

3. I _NEED_ NeXTcube's expansion bus pin data sheet! Please E-mail it to me
   or give a ftp site or some information where to find it. At least (!) I
   need power and ground pins!

4. Is it possible to connect NeXT to a normal multi-sync monitor? Refresh rate
   is 68 Hz, hsync and vsync, video.. I can't see why not. How much does
   used mono displays cost today? How many watts +12 V and -12 V megapixel
   needs to operate?

5. I also need keyboard connectors pin data sheet and information about
   power-on/off pin. (active level etc.). Is the power pin somehow connected
   to the power supplier so that it know when to turn on or does it supply 
   power to the motherboard all the time and there's a switch on the
   motherboard which switches diskdrives and monitor on/off..?

6. Any chance to get a complete schematics of NeXT?

Thanks in advance.
