Presenting! Accelerator Quest: One man's heroic struggle in search of
the ideal Amiga accelerator.
by Stephen Judd sjudd@nwu.edu
Some time ago, in a city perhaps not so far far away, my A1200 sat
on my tabletop, unaccelerated and unexpanded. It is a dark time for the
rebellion, as the galaxy's last great hope is slowly emasculated in Bahamian
legal debate. Stubborn resistance persists, however: in a bold stroke
against the Evil Empire, I embarked on a massive expansion of my Amiga 1200
in the form of a hard drive, monitor, and accelerator. There is plenty of
information on hard drive possibilities, and there is an AGA monitor list as
well, but as I searched I discovered that there was no comprehensive
resource that one could turn to for information about Amiga 1200
accelerators.
This is an attempt to rectify this situation. I scoured ftp sites
and magazine ads, and then asked for information on various newsgroups; this
text is the result.
Some notes:
This text contains information on the following A1200 accelerator boards:
Blizzard/Blizzard II
GVP A1230-II
Paravision (a.k.a. Microbotics) MBX
CSA 12-Gauge
DKB 1240 Cobra/Mongoose
M-TEC T1230 RTC
The first part contains a thumbnail sketch of each of the boards. The
second part contains comments I have received from various owners of the
boards.
If you want to find out more about an individual board, I suggest
that you email one (or more) of the people in the comments section who
actually own and have used one of the boards; I have found them all to be
most helpful.
The review is North-America centered; i.e., little information on
European prices or availability. There are several European users in the
comments section who can supply additional information.
Everyone seems to be very happy with their boards; it's not as if
there are any boards to avoid.
Some boards disable the PCMCIA slot: be aware.
Some boards suck a lot of power; you might want to get an external
power supply, like a Bigfoot. Some boards also heat up; little fans are
available to fix this for a nominal cost.
Prices are meant to be indicative of the going price, and are not
necessarily the cheapest prices.
Memory these days is around $179 for 4MB 60ns SIMM and $335 for 8MB
60ns SIMM.
I did not include AIBB benchmarks because a) the differences are
going to be minor and b) only one person sent me any :)
Some things to consider when examining the boards:
-Whether or not the unit has an on-board battery backed-up clock,
something the 1200 lacks.
-Whether the board allows SCSI and SCSI-II.
-Whether your PCMCIA slot is going to disappear.
-How many SIMM slots compared with how much memory you will need.
-The cost of the board (no, really?).
-Whether or not the board comes with an MMU. It is an option on many
boards, but is used by few Amiga programs.
The format for listing each board's features is
Processor Speed/Coprocessor Speed/Memory/SCSI
For example, "50/0/0/Optional" means 50 MHz processor speed, no coprocessor,
no memory, and optional SCSI. For SCSI, "optional" means that SCSI is not
included with the board, but is available as an add-on.
Please distribute this list everywhere you can. I ask only that you
leave the comments section intact.
So, without further ado...
Blizzard/Blizzard II:
====================
Advanced Systems and Software
Amiga Support Department
1329 Skiles
Dallas, TX 75204 USA
214-821-7776
There are three very encouraging reviews in c.s.a.reviews for this
board, but they are all from Europe. I called AS&S, and talked to a very
pleasant person there.
68030 MMU 50/0/0/Optional $525 (Advanced Systems and Software)
No 40/0/0/Optional $395
As you can see, they seem costly here in the states. Perhaps dealers would
have them for less.
European prices:
68030 MMU 50/50/4/Optional 500 UKP
68030 no 40/40/4/Optional 400 UKP
Blizzard 1220/4
68020 No 28/0/4/None 200 UKP
-Clock
-Autoconfigures
-SCSI is a small add-on card; SCSI-II available
-Mixing of different SIMM types is possible
-Two SIMM slots
-"Feature Connector" for future expansion
For more details on this board, see one of the three reviews in the
c.s.a.reviews archives. [MODERATOR'S NOTE: See the bottom of this review
for information on obtaining archived reviews. - Dan]
GVP A1230-II:
============
Great Valley Products
657 Clark Avenue
King of Prussia, PA 19460 USA
610-354-9495
Very fast unit, SCSI available. Requires GVP SIMMS, which are
faster but more expensive. Positive review in AmigaWorld.
030 MMU 50/50/4/SCSI $589 (Creative Computers)
030 No 40/40/4/Option $399 (Creative Computers)
-Clock
-Autoconfigures properly
-Requires GVP SIMMS (more expensive but faster)
-SCSI is a plug-in board. Theoretically other things (like a PC emulator)
could also be plugged into this board, although as far as I know none exist.
SCSI is DMA
-Two SIMM slots -- up to 32 Megs of memory.
-Might disable PCMCIA
I think the main advantage of this unit is that it is all-in-one;
that is, once you buy one you don't have to go SIMM shopping etc. On the
downside are educated rumors that GVP is trying to get out of the Amiga
business; note that GVP has no ad in the October AmigaWorld. (On the other
hand, once you've got the accelerator what do you need GVP for?)
Paravision MBX:
==============
Paravision (bought Microbotics)
500 East Arapaho, Suite 104
Richardson, TX 75024 USA
(800) 258-0533
Inexpensive unit. Stable. Microbotics has a long history of building
solid products.
030 MMU 50/50/0/No $299 (AmigaMan)
MMU 33/33/0/No $269 Memory World ($249 DeVine)
MMU 28/28/0/No $199 MW
Note: Paravision was offering the 33/33/0 direct, shipped, for $219. I have
no idea if this offer is still valid.
-Board does not autoconfig (supposedly will do so for OS 3.1). This means
that some libraries will be stored in CHIP RAM, until the OS is told that
FAST is available.
-No built-in SCSI; one alternative is to buy the Expansion Systems SCSI+
expander, around $99.
-Very positive feedback from owners.
-Only one SIMM slot.
-Clock
The main advantage of this unit is value: you get an awful lot for what
you pay for. I received a very enthusiastic response about this board;
obviously it is a popular unit. The primary disadvantage is the lack
of autoconfiguration, and the non-expandablity of the unit.
A review is available in the c.s.a.reviews archives.
CSA 12-Gauge:
============
CSA / Computer Systems Associates
7564 Trade St.
San Diego, CA 92121 USA
(619) 566-3911
030 MMU 50/0/0/SCSI $499 (Memory World)
(other configurations available)
-Autoconfigs properly
-No clock
-SCSI is non-DMA, which translates to additional CPU usage when transferring
data. Max data transfer rate is around 850K/sec.
-Supports 68030 BURST-Mode for memory access.
-Expandable to 32 megs.
-Can disable the unit for software compatibility
-Possible heating problems; inexpensive fans are available.
A bit expensive but well built. This was one of the first 1200
accelerators available, and it is still one of the highest performers.
It is often advertised in conjunction with "optional Networking Controller";
see the comments section for a description of this.
DKB 1240 Cobra:
==============
DKB
50240 W. Pontiac Trail
Wixom, MI 48393 USA
313-960-8751
DKB is another company with a long history of quality Amiga products.
This board is relatively new.
--- 0/0/0/Optional $189 (Safe Harbor)
030 MMU 28/0/0/Optional $189 (Safe Harbor)
030 No 40/
