Okay...a brief answer to your question...2.04 (I have 2.1, BTW...) works 
great on my 1 Meg Chip/2 Meg Fast A500.
 
I'm using it off a hard drive, so what I might say may or may not mean 
much to you, but then again it might.
 
I played with it for about 20 minutes after I installed the ROM, and did 
the 1 Meg Cip RAM mod - I found it to be much nicer that I had 
anticipated.  You *will* eat up a bit more memory, so unless you are real 
handy with Startup-Sequence, and can delete a few things to free you up 
some additional space ('bout 50k or so is what I figured...), then it 
really shouldn't be much of a problem.
 
In fact, I recall not being able to *easily* multitask a couple of big 
applications like Dpaint & JrComm on a 1 Meg machine (your mileage will 
vary, of course), so...
 
I dunno...ask some of the persons.on.the.net with A600's...

Dear Amigans,

Has anyone ever successfully connected an Iomega Bernoulli 90M
removable cartridge drive with a HardFrame 2000 (version 1.5c) SCSI
DMA controller?  If so how do you like/dislike the configuration,
performance, ease of use?  Would you do it again the same way?

I've heard from telephone sales people that the Bernoulli is only
sold with a SCSI host adapter.  And of course this board is for
IBM-type PC machines and not of much use to me.  The sales/tech
person on the telephone said that he could promise that their
Bernoulli would work with any other SCSI host adapter.  While I
understand that even though SCSI is a standard with defined
specifications it's like saying all ice-cream is the same.  So it's
possible that there may be some merit to the claim that Bernoulli
drives are exceptionally particular about what SCSI adapter they'll
talk to.  But when a sales person says that ONLY their package will
work, well for me a red flag goes up and I start hearig phrases like
"Danger Will Robinson" or the F-18A systems voice saying "Caution,
Caution, Caution".  So if any of you out there have real world
experiences with Iomega Bernoulli 90 and HardFrame 2000 SCSI
adapters or any SCSI adapter that works well with a Bernoulli drive
in an Amiga I'd be most happy to read your tale of joy or woe.  Thanks
for taking the time to read this, and hopefully reply.

Regards,

That's just it! How do I get the 32 bit memory, which is now outside of 
the autoconfig area, INTO the autoconfig space?? The address starts at 
around f001000000 or something like that and there is a huge gap between 
where that space starts and my 16 bit RAM ends, around f0003fffff.

I'm assuming the 68030 MMU can handle this, no? 

Help!

I really couldn't say.  The GoldenGateII simply passes through Amiga bus
cycles (with appropriate signal conversions).  There should not be any
loss of speed there.  If the CPU is fast enough, it should be able to write
out video data at a reasonable rate.  I'm sure a true Amiga video card
designed for the video slot would be faster, but probably ten times the
price of a low end VGA card.

The Sony by far has a better display.  I traded in a NEC 3D for the

Nope. The 68020 has a 256 byte instruction cache. No data can be
stored there. 

>There are no such things as stupid, dumb, or ignorant questions, just
>stupid, dumb, or ignorant people that will not ask questions.

With this in mind, why is it that Motorola have seperate instruction
and data caches? On the i486 there is a single 8k cache used for
both instructions and data. On the M68040, there is one 4k cache
for data, and another 4k cache for instructions. Which is better?

I hear that the Intel 586 is going to have seperate instruction
and data caches, as in the M68040, so this would seem to imply that
this is the prefered arrangement...?

The only thing I can think of is that you might not want your instruction
cache getting overwritten with less frequently used data, in a vector
operation or something. But this isn't really a serious factor, or
so I'm told...

Anyone any inspired thoughts?

Stephen.

WHAT!!???  I have had a CBM 2630 25mhz 030/68882 in my machine for the
past couple of years and my speed stacks up to any other comparible
accellerator card.  I have 4 megs of 32 bit ram in it and with a DKB
board can up that to a max of 64 megs of 32 bit ram.  As far as
compatability, I haven't had a *SINGLE* software title I own not run
under the darn thing unless it was a game that wasn't designed to run
under an 030 to begin with.

Where this guy gets his information and how you can post it to the rest
of the world mystifies me.

I should know about compatability because I work with a dealer who has
had just about every accellerator under the sun installed in different
2000's and the one we had the most problem with what GVP's 22mhz combo
board.  That thing just wouldn't work with hardly anything.  Most other
accellerators work as expected.  I currently run mine in a Toaster
system and it runs fine.

    Oh, come on.  *Any* moron could add one line to their User-startup

    You don't even have to look at the startup-sequence file; you just have
to add a line to your User-startup.  I just got my Amiga a couple of months
ago, and had never really used one before, and I figured out enough about
AmigaShell scripts and the startup procedure to set my machine up the way
I wanted it.

Right.  Harvard architecture allows for a more useful pipeline.  To

Well, again, we find self-modifying code a problem.  Just as a
side-point to make, C= and Apple have both said to avoid
self-modifying code.  I have never found a purpose for self-modifying
code, except in the case of copy protection, which I think shouldn't
exist.

How quickly things change when performance becomes an issue over
compatibility, eh?  I doubt seriously they have--if anything, if you
fall back into compatibility mode (if it is true that the P5's native
mode isn't compatible with the 486 and previous), you probably lose
both caches.

Probably.

Adding a ton of kludges wouldn't be beyond Intel, but it does appear
that for once they're trying to shrug off the kludges of their past
and start anew--I don't believe they'd do this by introducing Yet
Another Kludge.
