- PRODUCT NAME
-
- Fusion Forty
-
- BRIEF DESCRIPTION
-
- The Fusion Forty is an accelerator card for the Amiga 2000 series,
- using the Motorola 68040 chip running at 28Mhz (overclocked 25Mhz chip).
- It has an optional 32-bit RAM expansion, and the company promises future
- 32-bit expansion capabilities.
-
- COMPANY INFORMATION
-
- Name: RCS Management
- Address: 120 McGill St.
- Montreal, Que.
- Canada H2Y 2E5
- Telephone: (514)288-7825
-
- LIST PRICE
-
- The current list price according to the December 1992 issue of
- AmigaWorld is $1650 U.S. dollars. I've seen it advertised for $1200 by
- mail order vendors.
-
- FULL DESCRIPTION
-
- The Fusion Forty (F40), first announced in 1991 after Motorola
- announced the processor, was the first 68040 accelerator available on the
- market. It uses the "full" 68040 chip, not the slower "EC" version, running
- at an overclocked 28Mhz, with an FPU and 2 MMUs on the chip. It works only
- in the CPU slot of Amiga 2000 series computers. The Fusion Forty was
- originally designed to work under KickStart 1.3, but RCS has since updated
- their software to support KS 2.0 and has hence dropped their development for
- KS 1.3 compatibility.
-
- The Fusion Forty is a four-layer board with various chips on it.
- The biggest is the 68040 which comes with a large heat sink to dissipate
- heat. 32-bit RAM is managed by two SIMM sockets which accommodate both
- 1-megabyte or 4-megabyte SIMM modules of 80ns or faster RAM. Each SIMM
- socket accepts four of one size (either 1x8(9) or 4x8(9)) SIMMs, meaning
- that RAM can be added in 4, 8, 16, 20, and 32 meg increments. Note that
- this RAM does not autoconfigure. According to RCS, they don't autoconfigure
- the RAM for two reasons: so that they can overcome the Amiga 2000's 8 meg
- limit, and (they claim) autoconfiguring the RAM would make it slower.
-
- There are two 32-bit expansion slots on the Fusion Forty which are
- for future developments from RCS. RCS has hinted that they will be
- releasing a 32-bit CHIP RAM accelerator one of these days.
-
- Finally, the Fusion Forty is capable of reverting back to the
- standard 68000 mode via a hardware switch in the back of the unit,
- accessible at the back of the computer. (NEVER USE THIS SWITCH WHILE THE
- POWER IS ON.)
-
- MACHINE USED FOR TESTING
-
- I used my only Amiga 2000 for the testing. It is rather old (4.5
- years) with a revision 4.3 motherboard, on which I exchanged the Fat Agnus
- for the Fatter 1 meg Agnus two years ago. ROM is KickStart 2.04 which was
- installed in the beginning of the summer, and I still haven't gotten the ECS
- Denise yet. Oh yeah, I've got an ICD Flicker Free Video 2 installed which I
- would heartily recommend to anybody who's annoyed at flicker as much as I
- am....
-
- I installed one bank of one-megabyte SIMMs early this summer to give
- me 4 megs of RAM, and three weeks ago I added another bank giving me a grand
- total of 8 megs.
-
- There were some compatibility problems with the Fusion Forty and
- some of my hardware. I had to do the following before I could get the
- Fusion Forty to work correctly.
-
- 1. Replace the CMOS Gary chip with a new Commodore-manufactured one.
-
- 2. Replace the hard drive controller in my machine, an IVS
- Trumpcard Professional, with to a ICD AdSCSI unit since there
- seemed to be some incompatibilities with the IVS unit in my
- machine. I have been since told by two people that the TC Pro
- does in fact work with the Fusion Forty, but it's of little
- consequence to me, since I'm very satisfied with the reliability
- and performance of the AdSCSI.
-
- 3. I had to pull the GVP Series II RAM-only board from my machine.
- No great loss here since the GVP unit uses the same SIMMs that
- the Fusion Forty uses. RCS claims that this device is a
- definite no-no with the Fusion Forty.
-
- REVIEW
-
- This review is based on a Fusion Forty received during the summer of
- 1992. RCS has since changed their design, and I will try to incorporate
- this information into my review.
-
- RCS is a fairly small company in Quebec, Canada. In the course
- of my purchasing my Fusion Forty, I got to know some of their technical
- people very well, and I hope my experience with the Fusion Forty will help
- all of you out there.
-
- When I bought my Fusion Forty, RCS was offering a deal to US Amiga
- user group members. They were offering a substantial saving at the time,
- and their 68040 board was $600 cheaper than GVP's 50Mhz 68030 board (on the
- mail order market). I bought it with no RAM installed, since I already had
- four 1x9 meg, 70ns SIMMs which I intended to install onto the board. Please
- note that buying the Fusion Forty from RCS directly results in a 6-8 week
- wait if you live in the USA.
-
- Most people know that the 68040 increases the performance standard
- set by the Motorola 68000 quite dramatically. Upon arrival, I carefully
- installed the single board into my machine. Following all the instructions
- exactly, I booted up my machine in its native 68000 mode, and proceeded to
- install the custom software which recognizes the expansion RAM on the Fusion
- Forty board. Upon reboot, everything seemed normal. The computer came up
- quite normally, and I initiated the installation program on RCS's supplied
- disk. As soon as my computer tried to write to the hard drive, the machine
- froze. To make a long story short, I needed a new Gary chip and a new hard
- drive controller. I was sorry to lose my IVS Trumpcard Pro because I believe
- it is one of the fastest hard drive controllers available on the Amiga
- market.
-
- After I got all the parts necessary to get the Fusion Forty working
- again, I followed the instructions yet again, and and the installation went
- through without any problems.
-
- Now comes the good part. The Fusion Forty is a real speed demon in
- terms of raw computing power. My estimates (based on comparisons with a
- friend's A3000) imply that a Fusion Forty-equipped A2000 is somewhere
- between 2 and 4 times faster than an A3000/25. This is for real
- applications, not benchmark programs.
-
- And programs which use the FPU are even faster. My calculations
- estimate somewhere between 2 to 10 times faster than an A3000/25.
-
- What the heck, I'll include a couple of benchmarks:
-
- Benchmark Amiga 3000 Fusion Forty equipped 2000
- -------------------------------------------------------------------
- BeachBall 1.0 2.9 times faster
- InstTest 1.0 2.75 times faster
- FMath 1.0 4.5 times faster
-
- NOTE: All of the above tests were taken from actual data from AIBB
- version 4.65 with the 68040's copyback mode on. If copyback
- mode is off, and the caches are on, then cut the Fusion Forty
- figures in half.
-
- The Fusion Forty also increased my hard drive performance quite a
- bit. After doing some quick tests, these were the results.
-
- PROCESSOR READ WRITE SCAN
- ---------------------------------------------------------------------
- 68000 502k/sec 320k/sec 96 files/sec
- 68040 (non-copyback) 980k/sec 784k/sec 280 files/sec
- 68040 (copyback) 1.3meg 833k/sec 466 files/sec
-
- NOTE: All the above tests were performed using 512k buffers on a
- Quantum 120LPS and an ICD AdSCSI hard drive controller.
-
- Surprisingly, the Fusion Forty also increased the video speed of my
- machine, according to the AIBB WritePxl benchmark, which reported it to be
- equal to that of an A3000/25.
-
- The main problem with the Fusion Forty, as well as any other 68040
- based accelerator, is compatibility. All of my productivity programs work
- fine (DPaint III, DPaint IV, WordPerfect, Sculpt-Animate, PageStream 2.21,
- GNU Emacs, AmigaVision, etc.), but most older games and Euro-demos don't
- work. Star Control, Eye of the Beholder I and II, and most Sierra games do
- work, so no big loss. Also note that the large majority of productivity
- programs work very well in `copyback' mode.
-
- DOCUMENTATION
-
- The Fusion Forty came with just a 4-page flyer on how to install the
- hardware. The rest of the documentation came on the supplied installation
- disk. I was rather disappointed with the content of the documentation as it
- appeared that much was lacking. More could have been written on the 68040
- chip, but the files seemed to concentrate more on incompatible hardware.
-
- LIKES AND DISLIKES
-
- I'm very pleased with the Fusion Forty. As a CSI major, I spend a
- good deal of time on the computer. Add that to the fact that I co-operate a
- small graphics company and need the computer to be on for a good 4-8 hours
- daily (sometimes to do only raytracing). Since got the new Gary chip and
- hard drive controller, I have had no problems with the accelerator. I never
- use the hardware switch in the back as I really don't play games (any more).
-
- My only dislike about the Fusion Forty is the documentation, as
- explained above.
-
- BUGS
-
- This is not really a bug since it occurs only to me (I've posted my
- problem on Usenet). My hard-drive occasionally stalls at bootup. By
- stalling I mean that the drive light goes on indefinitely and the computer
- gives me a gray screen. I suspect that this is caused by my switching hard
- drive controllers but not yet reformatting the drive (thank god for RDB!).
- Anyways, a couple of ctrl-a-a's usually do the trick....
-
- VENDOR SUPPORT
-
- Vendor support is excellent. Not only do they promptly answer
- questions, but also they'll even call you back :)
-
- ADDENDUM
-
- Lastly, I would like to add that the Fusion Forty has changed
- slightly since I bought mine. They have added a Plug-n-Go board which
- allows for hardware copying of ROM to RAM (for faster ROM routine access).
- Originally, the software would boot up the machine, copy the ROM to RAM,
- give a "Fusion Forty Installed" screen, and reboot again from the ROM in RAM.
- It no longer does this. The Plug-n-Go board is a $50 (US) upgrade for
- Fusion Forty owners, and is available directly from RCS. I have not upgraded
- as I don't have the money or need.
