        I'm not convinced that adding multiple DSPs is the best way to
increase the number of audio voices. It's sort of like fitting entire
extra engines to a car to tow heavy loads instead of replacing the
current engine with a bigger one. I'm not saying "drop the DSP idea",
I'm saying that we need to stop and think about what we're asking for.

        If I'm not mistaken, DSPs normally have 2 or 4 channels.
Adding another DSP just to get 2 or 4 extra voices is going to be an
expensive exercise. I see a DSP as a number cruncher, highly suited
for real-time audio and video processing, not simply as a "sound
blaster card on a single chip". A more suitable approach would be
to 1: improve Paula to raise the base level of functionality, and
2: add another Paula, or a Paula compatible, dedicated D/A chip
on the DSP card. Paula compatibility/emulation keeps things clean for
audio.device, and the ability to add a multi-voice sound chip to a
DSP card gives A3000 owners an audio upgrade path (and A2000 owners
if a Zorro2 version is released).

	The transfer code in the IDE driver runs as a task, so there should be
no serial interrupt impact.  It will suck up more CPU time at fairly high
priority, so you might want to use larger serial buffer sizes.  The interrupts
used are level 2 (low priority), so serial level 5 ints should take priority.

Subject: A2091 & Q120LPS Weirdness.  HELP!
Date: 16 Oct 92 12:52:43 +1300
Organization: University of Waikato, Hamilton, New Zealand

Some collective netwisdom please...

I have a Quantum LPS 120 SCSI HD that I have had extreme trouble getting to go
with my A2091 SCSI controller (which BTW replaced a (apparently) dead
Microbotics HardFrame SCSI controller).  The A2091 is new, the Q120LPS is the
third replacement I've had (troubles go back a little way).

Hardware -	B2000 with Rev 4.3 Board
		Kickstart 2.04 ROM and Workbench
		1 MB Agnus
		Microbotics 2-8 Memory Board (2 MB populated)
		Commodore A2091 SCSI controller with v6.6 ROMs

Situation -	I've tried to install the Q120LPS and A2091 on this machine
with limited success.  I use the HDToolBox and I can successfully low level
format and partition the drive.  High level AmigaDOS formats of the drive also
seem to work.  Now the trouble starts...  I try an install my system software
on the boot drive partition - it goes okay for a short while and then it starts
putting requesters up saying something like; "Volume System has checksum error
at xxxxx".  The install routine then quits out.  From then on that partition
behaves really weirdly, if you double click on a disk icon it puts some error
message saying something like; "Draw is not a disk" and I can't access anything
on that partition.  If I reboot the machine that partition then sometimes the
volume names of the partitions are real screwed.  Those checksum errors appear
to lie in the blocks in the middle of the partition - the directory area?  I've
tried installing the software on other partitions with the same results.

To add a little twist to things, I removed the non functioning Quantum last
night and replaced it with my old Seagate 157-N.  It seems to work fine...  No
problems whatsoever... so far anyway.

What is wrong?  Has anyone ever experienced this behaviour?  Answers please!
Commodore engineers are free to comment as well...  ;^)

Thanks for any help.

I am having some problems with my SyQuest drive.  I have an Amiga
2500/30 with the 2.04 rom.  I have purchased update roms for the A2630
accelertor card, as well as my A2091 SCSI Controller.  My 40MB Quantum
HD is on SCSI ID #6, and I have my SyQuest drive set to SCSI 5.  When
the 2.04 HDToolBox program loads, it hass 7 listings for SCSI 5
(SyQuest)

	It looks something like this:
			SCSI 5 LUN 0 - SyQuest
			SCSI 5 LUN 1 - SyQuest
			etc...until LUN 7
If I choose LUN 0 and low-level format, an "info" command does this:
		
		SYQ: 	device info
		SYQ.1:  same info
		SYQ.4:  "     "
		SYQ.5:  "     "
I've tried formatting all lun devices...only lun 7 seems to work...
but then when I re-load the hdtoolbox, all lun #s are "changed" except
for LUN 7. If I save changes to all LUN devices, I get the same SYQ.x
crap. If I don't save changes to the other LUN devices, the drive works,
but when I try to download files to SYQ: or un-archive .lha files to the
device, the drive will do something like <write, write, spiiiiiiiiiiin>.
The access light comes on and doesn't go out until I re-boot! Then of
course I get a checksum error on the device.

Can anyone PLEASE help???

Please respond via e-mail...

According to the CERM (Computer Exchange Rate Mechanism)

Also US salaries are higher and the cost of living lower.
So Americans can afford an A4000 when Britons make do with

So if I add Domino to my A3000 I loose the internal flicker-fixer (Amber).
Domino would be great if it would input also A3000's VGA output and pass

Has anyone used a NEC 3D on an A3000 or A4000?  How do you like it?
Does it handle all Amiga graphic modes?  Does it allow overscan?

The 3D is rated for a 15.75 kHz horiz sync rate (at the lower bound):
is this close enough to 15 kHz to be able to handle all the graphic

  It was probably I who told you that, but I must have been tired when I wrote
that... I was wrong. After my post I realized that you could do it like this:

   1. Do a bunch of word-writes to ChipMem
   2. Do a bunch of long-writes to ChipMem

  If test 2 takes longer time to execute than test 1 you probably have a 16-bit
ChipMem bus. If it takes approx. the same time you most probably have a 32-bit
bus. (hope I got that right :-)

Subject: After the Amiga...
Organization: Grebyn Timesharing

OK, I was thinking about Commodore's next computer, after the Amiga.
Surely we all know it can't last forever, at least because the
Motorola 68K line is being outpaced by RISC chips in terms of
performance increases.  So what would the next Amiga look like?

RISC CPU, surely.  This would be a design intended for a long future,
and RISC CPUs, which might be a bit steep right now, will become much
cheaper as time goes by.  Which?  Well, I think a cheap one.
Certainly one with an MMU (scratch the AMD 29000) and FPU (scratch the
ARM).  Choose one with strong support and a bright future (scratch
88K, which is too bad since they're cheap; and scratch i860).  IBM
Power PC?  MIPS R4000?  Alpha?  Hmmm.... I'd have to guess the R4000
myself.  64 bits will carry a long way into the future.

Should the next Amiga run AmigaDOS?  I think not, at least not in the
state it's in.  Since there won't be any concern about existing
applications (wanna write the 68K emulator?) we can add the virtual
memory, the protected address spaces, the resource accounting that
many think should be there.  Our new speedy RISC CPU will have
horsepower to spend on more hardware abstraction, inlcuding the device
independent graphics.

That 114MHz custom chip set Commodore's described would do pretty well
for this machine.

I think the Zorro III bus will do nicely as an I/O bus.  Auto-config
is still unequalled in the rest of the world, as far as I can see.

Put the CPU, custom chippery, and space for 64M or 128M of RAM on the
motherboard.  Have a CPU slot that can take over for the CPU and
custom chips.  SCSI on the motherboard.  Ethernet?  Um...  Nah.

What about applications?  Who would buy a machine that didn't run
stuff?  Well, if we're gonna run an R4000, then (here comes some
serious flame bait) might I humbly suggest Windows NT as the operating
system?  See, it's already running on the R4000.  It can run DOS and
Windows x86 code with an included emulator.

Now, I think that maybe Windows NT adds too much abstraction for the
kind of good multimedia video and animation (and games!) that we're
used to, so in addition to the standard Windows interface, we'd want a
thinner interface to these neat custom chips.  I thought that maybe it
could run an AmigaDOS subsystem under it's micro-kernel.  Maybe not to
run AmigaDOS binaries directly, but the architecture would be the same
as AmigaDOS, so that many programs could be recompiled after some
amount of porting effort.  This is what would make this Amiga-NT
unique, and not just another Windows PC or RISC workstation.

Well, I can hear the mobs approaching with their torches and stones...
I'd better start ducking...

    Those slots are still a basic subset of the Zorro-II bus arrangement.  They
are lacking the proper buffering and other niceties which exist on a full
Zorro-II backplane.  As for if other cards will work, that is dependent on the
card in question.  Some may work, while others may have serious problems.

I recently took my 2000 in for repairs, and the power supply was found
to be the problem, and the shop fixed this.

Now, the machine itself works fine, but not so the SuperGen genlock.
The genlock works fine on my old A1000, so I'm pretty confident about
fingering the new power supply, and I'm going to have the shop fix it
again, with a bigger, better PS.

Several months ago I saw a recommendation for a 3rd party power supply
for the 2000, but I didn't save the article. 

So now I'm looking for suggestions (and products to avoid, if you know
of those, too).

without the 512K RAM card in the CPU slot?"  "I don't know what you're talking
about," he said, "they all come that way."

(Grapevine, by the way, took 4 months to send me a rev 4.5 motherboard, which
was defective.  I've been waiting a month and a half since I returned it for a
new one.)
