Few people are annoyed that it works.  Many are annoyed
that how it works isn't documented. :-)

Briefly (get on my mailing list if you want more stuff like
this (though usually much more long-winded :-) )), it
goes like this:

Screen pixels from the digital connections on the Amiga
RGB port are interpreted as bits by the unit.

The bits of two adjacent pixels are interleaved to form an
8 (or 6) bit sample.  First is higher, start with even or odd
depending on whether this is an even or odd row. 

These samples are then used to reconstruct a luminance
and chrominance channel.  Formulation of samples is
given below.

Every other row (within a field) has one chroma
difference, the others have the other.

Combine the luminance, chrominance, and last row's
chrominance, and you get a color signal.  Voila!


The exact makeup of a sample is the sum (or difference, it
alternates) of the luminance and the weighted mean of the
chrominance of this lores pixel and the the 3 to each side. 
The current value is doubled, and the result is divided by
8.

Obviously, this process can't be exactly reversed, so
the reconstruction is an approximation.  That's the
difference between "raw" and "display" formats you'll
often hear about.

I need the opacity for contact printing, not to PC boards, but to silkscreens.
I do my own color separations for four-color printing.
Overhead quality isn't quite good enough.
I do know tha the IBM laserprinter I used gave acceptible results, I've 
successfully used those transparancies as silkscreen matrices.
One other question - I've seen Apple printers advertised at school for 
large educational discounts, there's one laserwriter offered
for about $800, is it worth looking at? Would it hook up to my Amiga?
And also, are there any educational discount programs availible from
HP or IBM on their printers?

Does anyone know if the Adspeed 68000 accel and the Insider I board 
are compatible?  (The Insider I uses the 256K X 1 chips instead of the
newer Insider II which uses 1Meg X 1 chips (I think))

I plan to purchase a real Amiga soon, but right now, I'm just upgrading
my A1000.  Also, will they fit?  I'm not so worried about vertical
height, because I can always build a platform, but will the adspeed fit
over the insider board and not bump into the disk drive?

Ymodem is basically the same as XModem 1K with the addition of batch 
processing capabilities, and YModem-G is YModem that doesn't 
acknowledge the data blocks.  These came about because of the 
increase in phone line quality.  A phone today with a 2400 baud modem 
really doesn't need any error correction.  Now, of course there are 
much faster modems so error correction again becomes a factor....

I have a computer catalog called "Global Computer Supplies, 1-800-
845-6225).  They list a refill "kit" for the Canon Bj10 (and Bj300/330 etc.)
for $17.65 (twin pack).   This "kit" consists of two squeeze bottles with long

Bj10e requires a water based ink formula for its "bubble" technology...

Well, you may think about the future. Within a year the Amiga will probably
have some sort of RTG/DIG and _then_ you will have graphics boards that

Organization: University of Wisconsin - Parkside
Date: Fri, 24 Jul 1992 15:53:17 GMT


!!! Attention all Mega Midget Racer owners with 32bit DRAM !!!
--------------------------------------------------------------

Have you ever wanted your 32bit RAM to auto-config so that the entire
system is running out of 32bit RAM?  I'm not talking about moving kickstart
into 32bit RAM.  I'm talking about having graphics.library, intuition.library,
drive buffers, etc., etc., etc. in 32bit RAM?  (i.e. the 32bit RAM is added
before most system start-up routines are executed.)

Well, I wrote a program that accomplishes such.  Overall system performance
is increased slightly - over and above that of moving kickstart into 32bit.
BUT, if you have a NON-DMA hard drive controller, there's a big performance
increase - since the buffers are now in 32bit RAM.  (I have no idea how DMA
controllers will react to this - probably very poorly.)

The only thing that doesn't get moved - YET - is exec. :-(  Also, it only works
under 2.04 with 32bit DRAM.  And I've only been able to test it with the 8meg
board.  (It doesn't "pseudo-auto-config" any SRAM since I don't have any to
test it with.)

Now, is there any type of demand for such a program?  (I have no idea how many
MMR's are out there *WITH* 32bit DRAM.)

I tried an Exabyte-8200 out on my 1000 with a Supra SCSI controller
using BTN-Tape handler. I did not do extensive testing (it was a
loaner) but I 'tar'ed my 64 meg hardrive, read a file or two back to
the disk and did a table of contents listing, all with no problems.

Exabyte drives need to be internally terminated since there is no way
to supply the +5 volts needed for external terminators. This means they
are either pass through (no internal terms) or end the SCSI bus (with
terms).  The newer exabytes use SIP resistor packages (220/330 ohms I
think), the same as the terminators used in most SCSI drives,
older Exabytes use a DIP package, a little more difficult to find. A
word of warning, make sure you follow the little *dot* that indicates
pin #1 on the SIP and match it with a pin #1 indicator on the PCB
(either a square pad or a silk-scrren number 1). The SCSI ID is set
with little jumpers, look for a set of 6 L-shaped connector pins close
to the (left ?) edge of the PC Board with the SCSI ribbon cable
connector on it.  From left to right is bit 1,2 and 4. Adding a jumper
block, connecting the upper and lower pins, turns that bit on. You
would *probably* want one jumper in bit position 4: that is SCSI ID #4,
the default location for AmigaDOS 2.04's magtape command.

This is incorrect!. The GVP GForce 040 card for the 3000 has both jumper
and software selectable(on the fly) ASync and Sync modes. In Sync mode
the 040 card runs syncronously with the 3000 motherboard at 25mHz.

Right now, it's still pretty darned important.  I just got 2.04 a couple of
days ago - thanks to me being on a waiting list for a few months.  But what 
about those who can't upgrade yet?  
I think that it's a bit early for "2.0-only" major applications.  PD stuff
and little utilities, yes.  But not stuff like WP's.

Now new *machines* we need ... I'm not impressed with the 3000 ... :)
