-
- COMPANY INFORMATION
-
- Name: Microbotics, Inc.
- Address: 1251 American Parkway,
- Richardson, TX 75081
- USA
-
- Telephone: (214) 437-5330
-
-
- LIST PRICE
-
- List price unknown. I paid $399 (US) for the 50MHz 68030 version
- with no floating point unit (FPU) and no RAM SIMM.
-
- The unit is also available in 33MHz and 40MHz-EC versions, with and
- without RAM and FPUs. EC denotes the absence of an MMU.
-
-
- SPECIAL HARDWARE AND SOFTWARE REQUIREMENTS
-
- HARDWARE
-
- Amiga 1200 personal computer, with available LocalBus belly
- slot.
-
- A hard drive is recommended but not required.
-
- SOFTWARE
-
- OS 3.0, 3.1 compatible.
- Excellent compatibility.
-
-
- COPY PROTECTION
-
- None.
-
- The configuration and test software is hard-drive installable.
-
-
- MACHINE USED FOR TESTING
-
- Amiga 1200.
- 2 Meg Chip RAM, no Fast RAM.
- Kickstart Version 39.106, Workbench Version 39.29.
-
- Additional 4 Meg (70ns) Fast RAM added via SIMM socket on M1230XA.
-
- 50MHz 68882 FPU added (no oscillator necessary).
-
-
- GENERAL INFORMATION
-
- So you want to add speed to your new A1200? 40MHz isn't fast enough?
- You REALLY need that MMU... SCSI/SCSI-II isn't a priority?
-
- THIS is the accelerator for you!
-
- I've primarily been using my 1200 as a console and terminal, since
- the two Meg Chip RAM is not sufficient for many tasks any more. Yes, gone
- are the days when your Amiga could run quickly and multi-task efficiently
- with only two Megs of RAM. Count on 3-8 Megs for most serious applications.
-
- I had the need for 32-bit RAM expansion, knowing that this would
- instantly double the speed of my A1200, and also would allow the addition of
- a math coprocessor. My initial leanings were towards the Microbotics
- MBX1200Z, which came complete with clock/calendar, SIMM socket, and FPU
- socket.
-
- When I learned of a new Microbotics product which includes all these
- features, PLUS 50MHz acceleration with a TRUE 68030, I knew I had to have
- one. Not only has this board dramatically increased the overall speed of my
- machine, but also it has allowed me finally to run some of the Amiga's more
- sophisticated software (VistaPro, Art Department Pro, Lightwave, SAS/C 6.3,
- Deluxe Paint IV, etc.) which until now was out of my reach.
-
- Overall speed improvement estimates are:
-
- Item Speed Increase
- ==============================================
- Hard drive 40-50 %
- Graphics 70-100 %
- Serial port performance 10-15 %
-
- AIBB 6.0 results are as follows:
-
- Integer Graphics Floating Machine
- =====================================================================
- 11.70 4.72 19.16 A600, 2 MB Chip RAM
- 4.99 2.05 9.07 A1200, 2 MB Chip RAM
- 1.99 1.93 2.00 A3000/25 + Fast RAM
- 1.30 0.66 0.60 A4000/040 + Fast RAM
- 1.10 1.05 1.11 A1200 - See below...
-
- Thus, as indicated, the A1200 with M1230XA is 11.7 times faster at
- integer math operations than the A600 (no surprise here!).
-
- The last entry needs some explanation. The M1230XA comes with
- excellent configuration software (SetXA), which allows setting of many board
- parameters including RAM wait-states. When you configure the board for
- 50MHz, and 70ns RAM SIMMs, SetXA sets the wait-states to 4, which turns out
- to be rather conservative. Instead, I set the wait-states to 3, which not
- only runs reliably, but also runs faster as indicated by AIBB.
-
- The machine was 1.10 times faster with 3 wait states than with 4.
- However, doing this IS a risk, although I've had no problems with this so
- far.
-
- AIBB also revealed the HUGE difference between the RAM access of the
- A4000 and the M1230XA. The A4000 simply cannot keep up to the 68030-equipped
- A1200 in sheer RAM access speed.
-
-
- SOFTWARE
-
- The included SetXA utility is excellent, eliminating the need for
- many jumper blocks from the board and providing easy configuration.
- However, the software is rather conservative in its settings for
- wait-states, as outlined above.
-
- Another problem with the software is its need. Once the board is
- configured, you should not have to run the SetXA utility again.
- Unfortunately, the M1230XA does NOT AutoConfig its RAM on startup, and the
- SetXA software must be placed early in your startup-sequence in order to add
- the Fast RAM to the system. By this time, however, your drive buffers and
- graphics/Intuition libraries are already in Chip RAM. The operating
- system will run more quickly with this data in Fast RAM.
-
- While this is a problem, it is a minor one. It would be interesting
- to see how having graphics/Intuition in Fast RAM would affect the above
- speed comparisons. Also, games that need extra memory and don't behave will
- not be able to access this memory. I hope that most newer games will allow
- hard drive installation, or not need more than 2 Megs of RAM.
-
- Kickstart/AmigaDOS 3.1 is supposed to allow full AutoConfig ability.
- It seems that the present PCMCIA address space is right in the middle of the
- AutoConfig space. This doesn't stop the GVP accelerator from
- AutoConfiguring, however! Seems a small slip by Microbotics.
-
- The other included software is the TestRAM program, which does cyclic
- testing of RAM and is great for finding that bad RAM chip or area. I used
- it extensively when experimenting with the RAM wait-state settings, since I
- was worried about changing the SetXA defaults, but no errors occurred.
-
-
- HARDWARE
-
- As noted above, this thing really FLIES! Also, the clock/calendar
- module is fully AmigaDOS compatible, allowing you to use the existing
- system's Time and Date commands.
-
- The full 68030 is a boon to programmers using tools like Enforcer, as
- well as allowing the Kickstart ROMs to be mapped into Fast RAM. Even though
- this gobbles up 512K of your system RAM, it is recommended for full speed
- processing. If memory is really tight, you can always disable the FastROM
- option with the AmigaDOS CPU program.
-
- The SIMM socket is excellent quality, featuring the metal-latch type
- connection, rather than the typical plastic catches on most SIMM sockets.
-
- The FPU socket is a typical PGA socket, and takes a fair amount of
- force to insert your own 68881 or 68882. This is typical, however, and good
- contact is made.
-
-
- DOCUMENTATION
-
- The included documentation consists of two double-sided 8.5" x 11"
- pages, the User's Guide, and a registration card. Although the production
- quality is low (no booklet, colour, etc.), the content is very clear and
- concise.
-
- The User's Guide is laid out nicely, including a detailed diagram of
- the M1230XA circuit card. The Guide progresses through the following
- sections:
-
- 1. General Description
- 2. Basic Installation
- 3. SIMM Memory Installation
- 4. Math Coprocessor (FPU) Information
- 5. Realtime Clock Information
- 6. SetXA Configuration Software Guide
- 7. Troubleshooting
-
- The only concern about any of these sections lies in the Basic
- Installation section, Part 3:
-
- "..firmly press it completely onto the card edge. Because the
- connector is so wide, it may require some strength to press the
- card onto the Amiga's bus." ^^^^^^^^^^^^^
-
- Wow! SOME STRENGTH??? I had to reef on the sucker with a screw-driver
- as a lever, along with my hands stuck in there to keep things aligned.
- Getting it in was extremely difficult and frustrating, and getting it out
- will be damned impossible. It took about 5 minutes of aggravation until a
- solution was ironed out.
-
- In all fairness to Microbotics, I don't believe the problem lies at
- their end; and once the board is fitted, it makes great contact.
- Commodore's L-shaped bus slot makes insertion and removal very difficult,
- and NOT for the faint of heart.
-
-
- LIKES AND DISLIKES
-
- LIKES
-
- o The SetXA EEPROM configuration software is excellent and
- eliminates jumper blocks.
-
- o Instructions, while skimpy, provide all necessary
- information.
-
- o The SPEED!!!
-
- o The RAM!!!!!
-
- DISLIKES
-
- o Non-AutoConfig RAM expansion, while not terrible, is slightly
- annoying! (See above review for details and explanations.)
-
- SUGGESTIONS
-
- o Two SIMM sockets would have been better, but there is not
- enough room.
-
-
- COMPARISON TO OTHER SIMILAR PRODUCTS
-
- There are a number of other accelerator products out there, including
- GVPs, ICDs, CSAs and soon more. However, if you don't need SCSI-II
- capabilities, then this board exceeds the GVP A1230+ board in specs, and
- costs only slightly more. Here is a comparison chart:
-
-
- Board Speed RAM? RAM Amount Clock/Cal Full 68030 (MMU)
- =======================================================================
- M1230XA 50MHz YES up to 128MB YES YES
- A1230+ 40MHz YES up to 128MB NO NO
-
- The clock/calendar option is worth $30 US anyway, and the MMU is
- necessary for the serious programmer and for virtual memory support,
- as well as UNIX/Linux/Mach support.
-
-
- BUGS
-
- None found.
-
-
- VENDOR SUPPORT
-
- No experiences yet.
-
-
- WARRANTY
-
- One year, complete.
-
-
- CONCLUSIONS
-
- If your need is for speed, then this board is simply the fastest
- right now! The RAM speed excels over that of the A4000/40, and
- drive speed nearly doubles due to the processor speed and FAST RAM.
-
- Until a 68040 accelerator appears for the A1200, this card will
- provide king-of-the-hill performance. Microbotics is said to be working on
- a 68040 version of this product, but cost will be prohibitive to most mere
- mortals.
