Subject: Standards?
Date: 31 Dec 92 19:19:52 EST
Organization: Western Michigan University

A question that might not be appropriate here, but might have widespread
interest; there is obviously hardware/software talent haunting these
newsgroups, so here it goes ...

I was wondering about the general existence/usage of "standards" - for example
published standards (like IEEE) and de-facto standards like the IDE bus...

More specifically-

1. Has any of you purchased any of these standards? For example- the IEEE 802.3
standard - I imagine it's expensive - If so how much?

2. Is there a generic service that offers a variety of these standards? Maybe
at a cost that mere mortals can afford. I realize that university technical
libraries sometimes have these, but they don't seem to have all the latest
revisions, if they have the revs at all..

3. How do you get info on a de-facto like the IDE bus? Do you dig out the first 
IBM technical reference manual and reverse engineer the interface?
Or do the drive vendors help out?


I personally think that these "standards" are not really all that standard
since, in my opinion, the information seems to be guarded (I believe they are
high priced, and are not readily available online somewhere, such as the RFC's


Can anyone with experience on these statments please comment?

Does anyone out there know if the digital RGB input to the Amiga 1080
monitor (c. 1985) conforms to a wider industry format (such as VGA or
whatever)?  Specifically, I'd like to know if (as well as how) I can
connect a Powerbook's video out to my Amiga monitor.  Any ideas?

Thanks much,

Date: 21 Dec 92 22:37:52 PST
Organization: BBS

I'm having trouble making all 9 Megs of memory I have into as singular a chunk
as I can make it. Here's my setup:

I have a DKB Megachip board with 2 Meg of Chip RAM, an 8-UP Microbotics 16-bit
expansion board with 2 Megs on it, and a GVP 68030 Series II combo board with 5
Megs of 32-bit RAM. All of this on an Amiga 2000.

I've tried numerous things and have not been able to get all of the fast RAM
into a singular chunk of memory. This can get quite annoying when using AD Pro.
Since the 68030 has an MMU built in, shouldn't it be possible to merge all the
fast ram together? I've tried MergeMem, but that doesn't work either!

The 32-bit memory is outside of the normal autoconfig space and I'm wondering
if that has anything to do with it. Does anybody know how to fix this our has
had a similar problem and fix?

For the A600, you need to change the Agnus chip to go from hardware
default NTSC to PAL - the pin was needed for other purposes.

Distribution: world
Date: 31 Dec 92 07:14:11 EST
Organization: Not an Organization


     I just recently started using a hand scanner that I've had for
a while now and I have some questions:

     First, the scanner appears to be "old stock".  The various dates
are around 1990.  The version of Touch-Up is something like vers. 1.4.
The model number is JS-105-1M.  This is a grey scale scanner, nominally
giving 64 levels.

     The output is generally dark.  In character mode it's clean enough
but in "photo" mode I have to turn up the "light" control all they
way and it still tends to be dark.

     It's SLOW.  It's even slow in character mode really, but at
400 DPI it's essentially un-usable.  I don't think it's humanly
possible to move your hands that slowly for more than an inch.
Actually, I can rarely get an inch done at that speed.  300 DPI
is barely better.

     The power supply is for 120VAC 15 Watts in, and nominally
supplies 12VDC at 780 mA.  I haven't tested it yet.  I have good
accurate testing equipment for voltages -- I just haven't gotten
around to it.

     My first question is about the power supply.  Is this the
correct power supply?  There's no clue from the literature.  Actually,
I expect it is since it's unlikely that a piece of computer equipment
would be made using more than 12 volts.  It's possible, but unlikely.
On the other hand, does anybody know if I could bump the voltage up,
say to 15 - 19 volts safely?  Would that increase the brightness of
the lights and thus bring the grey scale into a more useable range?

     About the speed of the parallel port.  Freinds have told me
that hand scanners on other computers are faster.  Since they all
look alike, I expect that the speed problem in the Amiga is the
parallel port.  I don't know that much about parallel ports.  As
far as I know, there's no arbitrary "speed limit" on parallel ports.
The speed is determined only by signal hand-shakes.  So the speed
is effectively "as fast as you can get it to work".  Would changing
from a standard 68000 to a 33 mHz 68030 CPU in an Amiga 500 speed
up the centronics port and thus speed up the scanner?

     Recent hand scanners advertise 256 grey levels.  Is this
just a software change or is it a combination of hardware and
software changes?

     Recent ads in British magazines say that a colour hand scanner
is available for the A500.  Will anybody in North America be importing
these?  Has anybody used one yet?

Could someone help out those who don't know a specmark from a flyspeck

Maybe someone has specmark numbers for different Amiga models?  A

    Well, its not really quite as simple as that.  Many factors affect cache
hit rates, including relative data/instruction access densities, and usage
patterns for a particular system.  The associativity used in the cache can
also greatly affect hit rates as well.  (for example, a 64 way set associative
cache will generally invoke a better hit rate than a simple 4 way associative
arrangment).

   This is true to a point.  However, it isn't the breaking reason for using
a non-unified arrangement, though it does allow for a better seperation.  One
important advantage to using seperate code/data caches is concurrent access to
cache operands.  This is not possible in a unified arrangment.  Indeed, you will
see instruction/data mix effects as described above with a unified cache though.

I've had the same problem with a 1081 that's been through some heavy use
over the last 6.5 years. What I did was to open it, blow out the dust
and resolder some suspicious looking areas. That worked for me.

>So: How serious a problem is this? How expensive to fix?

Took me about 30 minutes.

I've got another problem with my 1081 that wasn't completely solved by
this. When using it to watch some TV and the current view is relativly
bright, the picture rocks down a bit which is annoying. Any suggestions?

You can't.  The A2232 only goes up to 19200 (other than that funny MIDI rate).

Technology has improved in the past 50 years. :-)

Although films are still often shot at 24 fps, each frame is flashed
_twice_, giving a 48 Hz flash rate.  Most people's eyes don't notice this
-- especially considering that there usually isn't the very sharp constrast
between adjacent picture portions that you find on computer screens.

I believe that you need to flash things at people about 40 times a second
(given low constrast images, like movies) if you don't want them to notice
flicker.  You only need to actually shift images something like 15 times a
second and people won't perceive it as "jerky" motion.

These numbers can vary a lot of what's being displayed, though.

Even with all the monitor controls maxed out the damn screen

Is there any way I can get the machine to plunk the display in
the center of the screen (what a concept!) so I can adjust

To convert the A1000's parallel pinout to the "defacto standard"
pinout wire up two female DB25 connectors with everything straight
thru EXCEPT for crossing:
	pins 14 and 23		(GND & +5)
	pins 16 and 25		(GND & Reset)
	pins 15 and 24		(GND & NC)

This will result in a symetrical converter.

To synch quality digital audiosamples(via sequencer)
 with video,( say from
a camera, or internally generated)  on an Amiga, what would be the
hardware that would do this? I have a rough idea what
the toaster does, and what programs like studio vision do on
the mac,,( hard disk recording,, midi keyboard, etc), does the
amiga have the hard/soft ware to accomplish similar tasks and
put them together?
or would you have to emulate another computer?  Iknow this may be
a question with a lot of different answers, but Im fishing around,
,,,, going to buy a box fairly soon, 
OR,, if anyone knows of a suitable faq or other group concerning
the above question, I would appreciate a point in the right
direction.... please simultaneous e mail reply also if possible.
thx.   Mark
