[comp.sys.amiga] '020/881 accelerators - Compatible?

-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_

A subject I haven't seen addressed (at least since I've been reading
this newsgroup (not that long)) is what level of compatibility with
existing software/hardware does an '020 board provide on the Amiga.

If I put a Hurricane (tm) or the Lucas (tm) project board in my A1000
am I going to be able to still boot most/all/few of my programs like
FSII, JET, Arkanoid etc.???  

I assume that decigel will handle virtually anything I'm running in
the standard DOS environment that I use with my hard disk etc. but
will I have a box full of games that won't run unless I swap the 68K
back into the system??

I'd be VERY interested in seeing a compatibility list posted that's 
been provided by the makers of such boards.  If this subject was
already run into the ground prior to my arrival to this newsgroup
than I appoligize and possibly someone could just mail me the info.

I've started useing my 1000 extensively for SculptAnimate3D and boy
could I use a 10(?) fold improvement in speed!!, but I'm not ready to 
dedicate the machine solely for this use, as I would have to do if
accelerators limit my software/hardware compatibility.

So far the only piece of software that won't run on the Lucas Board
is Soundscape, but I use pretty plain vanilla programs, compilers,
utilities, paint and imaging programs, and the odd game. It runs all
of the Commodore diagnostics which they use for burn-in.
It is still 3 - 4 weeks before Transactor hits the stands, and I'm
still putting the final touches on the new PCB layout. It is my intention,
once I have the time, to list any software or hardware which is uncompatible
with the Lucas board and post them on both USENET and BIX.
The real point here I guess is that even though I've done what I can
to make the board compatible, with PD hardware its the more adventuresome
of you out there that get to be the Beta-testers. You can always hang
back a month and see how I did. My chief ambition with the board was
to make a 68020-68881 pair available to those who need it for as cheap
as possible.

I don't know about the Hurricane board but the "original" CSA board
still runs FSII, JET, MarbleMadness, and ChessMaster2000(not sure about
this one - it's been a while) on my A1000.  MarbleMadness (in 32-bit
RAM) plays noticedly faster and with two players it's like a normal
A1000 w/ one player.  I just got PixelMate and have had no problems.
Digi-View, when processing changes in the color menu, is significantly
"speeded up" by an '020.

If anyone wants to send me a list of programs and their experiences I'll
tabulate them and produce a summary in, say 3-weeks?  Addresses below.
Send the game/utility/whathaveyou as well as what '020 board, how much
if any 32-bit RAM, and experiences you'd like to relate.

Big assumption!  Some games, like the FD (Freely Distributable) Amoeba,
won't work because they rely on the "speed" of the 68000 when they're
doing their display hacks and not, for instance, waiting for the
vertical blanking to occur before updating the screen.  (Correct me if
I'm wrong/misphrased/misinformed)

I'm curious to see what happens to all the software when the V1.3 math
libraries arrive with their detection and use of the '881!!!

The question I have concerns the price difference between the Hurricane and
CSA 68020/68881 boards.  The CSA board is substantially more expensive and
yet is listed as a 14Mhz board (as opposed to the Hurricanes 16Mhz and 20Mhz
options).  Can anybody tell me why I should buy the CSA rather than Hurricane?
Is it more compatible?

Do both of the boards come with a way to switch back to the 68000 through
software or do you actually remove the chip and make changes that would require
opening the box if you have incompatible software?

I would really appreciate answers folks, I just sold my Atari 1040 ST and that
gives me the money to get one of the accelerator boards.

The Hurricane board REQUIRES removal of the 68000. The CSA board lets you have
the 68000 on the main board.

Besides removal of the 68000, intallation of the Hurricane board is just that.
Depending on your B2000 model rev, the CSA board WILL REQUIRE hardware 
modification of the motherboard (which include soldering), which will VOID
YOUR WARRANTY.  Also these modification are not for the "casual" user.  Even
after these modifications, the CSA board MIGHT not work.  As far as I know,
thes Hurricane board does not have the same problems as the CSA board.

GOOD FOR YOU! :-)
