II. Introduction
================
The Fusion-Forty accelerator is a Motorola 68040 based CPU card for Amiga
1500, 2000, and 2500 style machines.  It provides a means for increased raw
CPU power, as well as RAM expansion on the card.  It is manufactured by RCS
Management, and was designed by Suresh Sukhdeo in Montreal, PQ, Canada. 
(See contact information at end).

1. What machines does it work with?
===================================
Any Amiga with an A2000-style CPU-slot, such as the A1500, A2000, and A2500. 
It will NOT work in an A3000 or A4000 style machine.

Motherboard revision seems to make a difference concerning the Fusion-Forty,
and Zorro-II expansion cards.  Reported successes include:
  - A2000"C" Rev 6.2, ECS Agnus and ECS Denise
  - A2000"C" Rev 6.0  ECS Agnus and ECS Denise (Kai Kohlmorgen, Bjorn
                      Frostberg)
* - A2000"B" Rev 4.0  ECS Agnus and ECS Denise (Niels Knoop)
  - A2000    Rev 4.5  unknown (Blair Wickstrand)
  - A2000    Rev 4.4, ECS Agnus
  - A2500    Rev 4.3, ECS Agnus and OCS Denise (Brian King)

2. Specs and RAM types of the card?
===================================
There are two known models of the card:
  - Fusion-Forty 28MHz model, with 25MHz 68040 overclocked to 28MHz.
    Takes 30-pin SIMMs, 70ns or less, 8 SIMM sockets.
  - Fusion-Forty 35MHz model, with 33MHz 68040 overclocked to 35MHz.
    Takes 30-pin SIMMs, 70ns or less, 8 SIMM sockets.

Either parity or non-parity SIMMs will work.  Additionally, it can take
either 1 or 4-Meg SIMMs in either of its four-slot banks.  The first four
SIMM sockets make up one bank, while the last four make up another bank. 
Each bank's sockets must be populated with the SAME TYPE of SIMM (ie.
either 1 or 4-Meg), but each bank can have a different size of SIMM.

Thus, possible RAM configurations include:
4 Meg, 8 Meg, 16 Meg, 20 Meg, and 32 Meg.

3. What Zorro-II cards work with it?

4. What version of the OS does it work with?
============================================
a) Problems with 68040.library?
   - Some people attribute various system problems to the use of a custom
     68040.library.  Certain 040-specific applications don't seem to like
     it, while working fine with other cards which can use it.
   - Many problems may not be related to the 68040.library, but instead to
     the Fusion-40 using an 8K page-size for MMU operations, instead of the
     typical 4K page-size.
   - You CAN use the normal 68040.library, by disabling FASTKICKing, and
     not using any of the SetFF/MoveMH tools.  This allows you to use the
     Commodore 68040.library (37.4), and test for compatability problems.
     However, without the FASTKICK support, your speed will drastically
     decrease.
b) KS 1.3 support
   - While 1.3 is still supported, and can then be used as the launchpad
     for FASTKICKing a newer version of the OS via a Kickstart-file, it
     is not a recommended environment for use of a 68040 based accelerator.
   - As Niels Knoop so accurately stated: "This isn't 1986 anymore!"
c) KS 2.x support
   - Yes
d) KS 3.x upgrade (Plug'N'Go ROMs)
   - Yes, with upgrade to Version 3.4 of Plug'N'Go ROMs

5. Emulation Support?
=====================
a) ShapeShifter (SS)
   a.1 - Mac ROM type
     A common problem with ShapeShifter and the F40 seems to be that the
     CopyBack cache must be disabled during SS operation.
  
     Below is a table of Macintosh ROM versions which work with 3.1a:
       Macintosh Model     Version.Subversion     Size     All Caches?
       ---------------------------------------------------------------
       Mac LC-III              124.34            1 Meg     NO COPYBACK
       ???                     124.17            512K      NO COPYBACK

   a.2 - MacOS version
     System 7.0.1 (freely available from ftp.apple.com) with SystemTuner
     1.1.1 works fine.

     System 7.1 ????
     
     System 7.5.x ????

     Problems with the Sound-Control-Panel on many setups, fixed by getting
     the latest Sound-Manager package from ftp.support.apple.com somewhere.
     
     However, with System 7.0.1 and ShapeShifter 3.1a, the latest Sound-
     Manager package did NOT work at all.

   a.3 - ShapeShifter settings
     It seems that none of the MMU settings for ShapeShifter will work with
     the Fusion-Forty 32-bit memory.  Thus, if you put the Mac ROM image
     there, you cannot turn on the "Write Protect ROM" option. 
     Additionally, if you want your Mac video memory to be in 32-bit mem,
     you cannot use the "MMU Refresh" option at all, which sorta defeats
     the purpose.

     According to Christian Bauer, author of ShapeShifter:
      "I suspect that the F40 uses the Transparent Translation registers to
       enable Copyback and not the MMU table like the 68040.library does.
       This would break all of ShapeShifter's MMU related functions (and
       some of MacOS's cache handling)."

b) EMPLANT (Mac/E586)
   - Works with 3.1 ROM upgrade, 3.4 Plug'n'Go ROMs for Fusion-Forty, and
     FASTKICK option disabled.
c) AMAX
d) PC-TASK 3.1
   - reported as working

6. Virtual Memory Support?
==========================
VMM versions 2.0, 3.0, and 3.1 are all reported as working.  The key is
to make sure you run MoveMH (version 1.2) early in your startup.
(Christian Bednarek, Blair Wickstrand, Kai Kohlmorgen).  
I haven't been able to get it to work, however.

Kai Kohlmorgen's information looks like:
Memory: fixed size Type: any File "hd1:pagefile Size: 8MB 
                Min 200KB WriteB: 100KB 
                VM Pri: 40 
Miscellaneous: Enabled: Cache ZII RAM Show VM in WB Title Memory Tracking 
                           other options: disabled 
Task: Default: N N 
 
7. What is the latest software and ROM release?
===============================================
Plug'N'Go ROMs                    3.4
SetFF                             1.79
MoveMH                            1.2

8. Problems and solutions
=========================
a) CopyBack problems (with 2.x of the OS or greater)
   - This may be a problem with the Gate Array Logic (GAL) chip at location
     U37 on your Fusion-Forty card.  If it is a GAL, not a Programmable
     Array Logic (PAL) chip, it should be replaced with a 10ns PAL version.
   Testing:
   - if your machine runs reliably without the CopyBack cache of the 68040
     CPU enabled, but crashes often when it is enabled, it MAY be this part.
     However, some older software (pre 2.x OS stuff) doesn't like the
     CopyBack cache of the 68040.  Try booting with a clean system, and see
     how that goes.
b) Enforcer hits with ramlib.
   - Try using MoveMH 1.2, *NOT* MoveMH 1.1 which had a bug.
c) GVP Series II SCSI+RAM (HC+8) system with 16-bit fast mem won't work
   - Try adjusting the speed jumpers of the controller.  Niels Knoop found
     that J11 must be set, but that the jumper near the SCSI chip must NOT
     be changed.  (This keeps the SCSI chip running at 7MHz)
   - NOTE: I've had no problem in my system with BOTH J11 and the SCSI speed
     at 14MHz...
d) My Fusion Forty doesn't boot / is very slow with an OS 3.1 ROM
   - This is caused by older versions of the Plug&Go-ROMs on the F40.
     Upgrading to the new Version 3.4 should fix this, but you can
     get older versions to work as well. If the F40 doesn't boot at
     all, hold the right mouse button during reset to bring up the
     F40 control menu and select NOFASTKICK from there. It will
     boot then, but won't do its job. To regain Fusion Forty speed
     adding the Fast-RAM, patching and installing the Kickstart
     image in it and enabling the FPU has to be done by the program
     SetFF which should be on the F40 software disk or can be ob-
     tained from RCS.
     (Niels Knoop)
e) My Fusion Forty crashes after I installed a new OS.
   - The Fusion Forty Plug&Go-ROMs are not compatible with the
     original 68040.library from Commodore. Be sure to re-install
     the small special 68040.library which came with your F40.
     (Niels Knoop)

9. Future growth?
=================
a) SCSI on-board
   - Supposedly
b) 68060 adapter
   - Unknown.  RCS may skip that particular upgrade path and go straight
     to an 060-specific accelerator, perhaps even with PCI graphics on
     the card (with my suggestions).
c) CHIP-RAM accelerator
   - Was on the backburner due to static-RAM costs.  May yet come to light.

10. Why is access to my DMA-SCSI controller so slow?
====================================================
DMA controllers can only transfer to memory within the 24-bit memory space
(MEMF_24BITDMA), also known as AutoConfig memory space.  Your Amiga can only
have 8 Megs maximum of AutoConfig memory space.

Since NONE of the Fusion-Forty's memory is within that space, your DMA SCSI
controller doesn't know how to directly access it with a DMA transfer. 
Instead, it will usually either choke (some controllers with wrong ROM), or
it will allocate a small buffer somewhere where it CAN do a DMA transfer. 
It then DMAs to the small buffer (either in 16-bit FAST memory, or in CHIP
memory), and afterwards, copies the information byte-by-byte into the 32-bit
RAM target area on the Fusion-Forty.

If you have NO 16-bit FAST mem in your system, and have a DMA controller,
GET SOME!  Otherwise, with the small DMA buffer in CHIP memory, your system
will crawl (since access to CHIP mem is shared with the custom-chips).  With
my GVP SCSI controller, I go from 780K/sec to around 1.1 Meg/sec just by
adding two megs of 16-bit fast memory.  Additionally, some of that memory
comes in handy for drive caching, ShapeShifter (the Mac ROM can go there),
or other purposes.  Sure its slow, but its providing a dual purpose.
