For the big stuff, sure. Not for the small stuff (glue, I/O, memory, and
other stuff that does not suck much power).
Here is a test. Boil some water in a big pot, as if you were to make

Today I picked up a NEXT Color Printer in a thrift shop. From what I have found, it is a
PostScript color
printer using a Cannon Bubblejet engine, with a SCSI interface (altough it appears to have
a standard LPT
Centronics interface as well). It is Model N2005. It has the extremely interesting
serial number of
ACS-00000017.
The machine, aside from being dusty, is like new.
I don't have a NEXT system, and I have not tried hooking it up to my PC (yet). Does
anyone know if this will
work (using a generic PS driver)?
In any event, if this is the NEXT item on your list to complete your NEXT system, I would
be happy to

I have a NeXT color printer.
From what I know about NeXT printers, none of them are
PostScript. The
NeXT printers are similar to monitors or a 'display
device', in that the
Display PostScript engine in the operating system is the same engine
that handles printing. This would make the use of a NeXT printer on a
PC require a filter, which I don't beleive exists. Both of the
centronics ports on the printer are SCSI. I've never seen one that has
a parellel port.
The printer is interesting to say the least. If you pop the cover off,
you'll see how complicated these early inkjet printers were. There's a
maze of tubing running all of the printer through all kinds of pumps and
reserviours to move the ink. I've rebuilt mine from the ground up, and
I can tell you it's not an easy task. I had to do this because there
was ink that had dried in the lines. It's amazing these printers
actually work.

Well, you are mistaken about something. This printer has _three_ Centronics ports, two
are SCSI, and the
other is smaller, the size of a parallel port. My theory is that this is the difference
between a Model 2004,
which is documented in web literature, and Model 2005, of which there may have been few

Very interesting. Mine definitely has only 2 50-pin Centronics ports.
The serial number is 00000078, and is an N2004. What makes this even
more interesting is that NeXT's didn't have a parallel port (that I know
of).
There's an easy way to test if a) That's a parallel port, and b) it has
an on-board PostScript processor. Just connect it to a PC and send some
PostScript to the printer. That would make a nice inexpensive
PostScript color printer if this works, as ink is still available.

Ok, here's the report. The printer works, and runs the self-test (in full color).
Still has ink!
The 36-pin port is a parallel port, and does receive data from the PC. You select from
SCSI/Parallel on an
LCD menu on the printer.
The printer did not understand PostScript. However, on the printer, there are a number of
different "Modes"
and other options that are selectable, and without a manual, it isn't clear what they
do. One could be
PostScript, I'll have to do some more tests. But plain ascii sent from the PC worked
fine.

With all due respect, I disagree. The term "Centronics", whatever its original
meaning, refers to a type of
connector. Looking at the Jameco catalog, for example, the catalog pictures 14, 24, 36
and 50 contact
male and female connectors, all referred to as "Centronics". I have never heard
the term "blue ribbon" used
to describe these connectors.
My understanding is that Centronics was the first to use this type of connector on its
parallel printers, so
when it became the standard type connector the name stuck.
Parallel port nomenclature now has a number of different terms, based on function and
standard, not type of
connector. SCSI connectors are sometimes Centronics type, but not always.
In any event, the "36-pin Centronics Connector" is a parallel connection, and
the PC was able to talk to this
printer.
BTW, this type of connector, regardless of the number of pins, when made for ribbon
cables, is referred to
by Jameco as "IDC Centronics Connector".

I've seen plenty of other connectors mis-named as

I have.
It was a cable with what looked from the outside to be DB25 male
connectors on each end. Each connector had pins 1,2,3,4,5,6,7,8,20.
What made it a DB9, rather than a DB25 with missing pins is that it was a
molded connector that was made that way, with no holes for the other
pins.
Do TELEPHONE people who have been using the larger connectors since before
Centronics Corp existed, call them "Centronics connectors"?

There are plenty of folks who think collectors of old computer hardware are
odd. One oddity I'd like to see adopted is a dedication to correctness in
detail. Where the language used in our society is rapidly heading for the
point at which everyone will only be taught a single syllable, leaving
inflections to communicate whatever little meaning there is, I'd suggest we,
at least, take it upon ourselves to learn and use the correct terminology,
painful as it may be.

are sticklers to the point where they get pissed when someone
shows up with modern eyeglasses or cotton instead of wool
clothing, etc. They called them "Farby's" for the phrase "Far be
it for me to judge".

There was a recent thread on the linux-kernel mailing list about
changing all references to KB, MB, etc. to the new standard KiB,
MiB, etc. Some people were for the change, since the new names
are unambiguous, while others think it is kind of ridiculous for
a third-party to change the definitions that have been accepted
for years. I'm in the camp that 1KB of RAM is 1024B, and 1MB of
hard drive is 1024*1024B. That's what they've meant for years,
and the hard drive manufacturers playing with specs and getting
the public thinking 1MB=1000*1024B is not a good reason to change.
I'm not pedantic, though. While I use "Ethernet", I don't get
bent out of shape when people use "ethernet".

Even so, Tony, shouldn't WE, the purported experts on the archaic computers,
be able to come up with a precise, if not communcative to the masses, way of
saying what we mean without a long clarification? If WE use the wrong term
amongst ourselves, we'll certainly never show others that there's benefit in
calling it a crescent wrench when, to some folks, "the silver-colored
thingie," would do.
It would, IMHO, save lots of time and bandwidth, not just here, but all
around.

OK. I doubt this thread would have gone as far had the original
description of the printer been something like 'It's got 3 of those
Centronics-style connectors on the back. 2 50 pin ones (SCSI) and a 36
pin one which might be a Centronics parallel interface'.
There is a big difference (IMHO) between 'Centronics style connector' (a
common, understandable, even if technically incorrect, term for the
connector series we're discussing) and 'Centronics port' (a particular
type of parallel printer interface).

Damn. While I generally disagee with Richards approach on most things his
recent postings are things I agree with. Remember the legend of the Tower of

There are plenty of folks who think collectors of old
computer hardware are odd.
One oddity I'd like to see adopted is a dedication to correctness in detail.
Where the language used in our society is rapidly heading for the point at which
everyone will only be taught a single syllable, leaving inflections to
communicate whatever little meaning there is, I'd suggest we, at least, take it
upon ourselves to learn and use the correct terminology, painful as it may be.
more below, BTW.

A lot of this nomenclature problem came about when folks started referring
to the DB25 (and it is a 'B' shell) as an "RS232" connector.
IIRC, both the 'D' subminitature connectors, e.g. DE9, DA15, DB25, DC37,
DD50 ... and the "Blue-Ribbon" series were Amphenol products, the patent on
which expired in the late '70's. Consequently the trade names became muddled in
various competitors' nomenclature. If somebody has kept old Cramer, Newark,
Allied, and other catalogs of the late '60's and early '70's, (which I
haven't)
the nomenclature should be much clearer there.
Tony is correct.
Regrettably, Jameco has fallen into the bastardization/mongrelization of the
language. Looking at a page of a 1962 Allied Radio catalog, I see listings
and illustrations of the Amphenol "Blue Ribbon" connectors in sizes running
from 8-32 contacts. They obviously derived their name from the blue Diallyl
phthalate dielectric that carried the ribbon-like contacts.
Don provides a hint to the correct approach.
Invoke the 10 year rule.
In place of current accepted sloppy terminology,
how many remember what they were called THEN?

Today I picked up a NEXT Color Printer in a thrift shop. From what I have
found, it is a PostScript color
printer using a Cannon Bubblejet engine, with a SCSI interface (altough it
appears to have a standard LPT
Centronics interface as well). It is Model N2005. It has the extremely
interesting serial number of
ACS-00000017.
The machine, aside from being dusty, is like new.
I don't have a NEXT system, and I have not tried hooking it up to my PC
(yet). Does anyone know if this will
work (using a generic PS driver)?
In any event, if this is the NEXT item on your list to complete your NEXT
system, I would be happy to
discuss a deal.

We've got some odd Kodak printers at work, connected to some
older PowerMac's, that use SCSI for the interface as well. My guess
is that, at least in this case, the Mac printer port wasn't fast
enough for their liking so they put it on the SCSI port instead. I
don't see where that would be the case with the NeXT though given the
very high-speed nature of it's printer port. To do full Postscript
Level II at 400dpi and 8ppm (NeXT Laser printer) with all the work
being done by the host CPU is going to take a pretty fast serial
interface.

Did some NeXTs ever use the 'raw video'
interface to the laser printer?
We discussed this interface on the list about a month ago, it's a very
low-level interface where you have a signal that controls the laser
directly. Once the host has started a piece of paper moving through the
printer, it has to then send data to the laser control input in real
time, at about 11Mbps (IIRC).
Everything I've ever seen concerning the printer's interface
refers to it as a high-speed serial interface, though I've rarely
seen actual throughput figures. I have no doubt that the commands
sent out it are fairly low level though considering the lack of
onboard intelligence on the printer. It doesn't even power on until
the NeXT is powered on. The interface also provides for some status
back to the CPU as well. Due to the host CPU needing to do all the
work, I would think that the amount of data streaming out to the
printer engine, as well as strobes checking printer status, would
require a good deal more bandwidth on the interface than a more
standard connection.

I want to say the data rate of the printer port is 1.5 Mbit/sec, but I
can't remember for certain and it may very well be 11 Mbit/sec instead.
I'm nearly certain the exact rate is mentioned in either "The NeXT Book"
or in the comp.sys.next.hardware FAQ.

Everything

refers to it as a high-speed serial interface, though I've rarely
Which the Canon 'video' interface technically is. You send a serial bit
stream to the laser driver. With no framing or any other kind of protocol. There's a serial clock/data pair for status (paper
out, jam, errors,
paper size, etc) and commands (select paper tray, select manual feeder,
and so on). And some ready signals so both sides know that the other side
is turned on.
The actual pinout for the connection is:
1 LP CLK
2 LP Data In
3 LP Data Out 1
4 LP Data Out 2
5 LP PWR Enable
6 GND
7 GND
8 GND
9 NC
This sounds suspiciously like the Canon 'video'
interface. Just out of
curiousity, what connector is used (the Canon standard one is a DC37-S on
the printer).
The connection on the CPU end is a DE-9M. My NeXT laser
printer is sitting in my office awaiting replacement of it's feed
roller and ejection gear, so I can't doublecheck the connector on the
printer end. I believe it's the same as the CPU though, as I don't
recall the cable being different on each end.
