PRODUCT NAME
Emplant Deluxe (with Mac Software v4.6)
BRIEF DESCRIPTION
The Emplant is a Zorro-II board that allows emulation of various
different computers via your Amiga. Currently, the only emulation that is
written for the Emplant is the Macintosh, which emulates a full-colour
Macintosh on your Amiga. The type of Mac emulated by the Emplant is
dependent upon your CPU speed.
COMPANY INFORMATION
Name: Utilities Unlimited International
Address: 790 Lake Havasu Ave Suite #16
Lake Havasu City, AZ 86403
USA
Telephone: (602) 680-9004
FAX: (602) 453-6407
LIST PRICE
Unknown. I paid $399 (US) for the Deluxe board.
SPECIAL HARDWARE AND SOFTWARE REQUIREMENTS
HARDWARE
68020 CPU or greater.
Mac 256K ROMS (v1.1-v1.3)
Minimum of 2 megs of FAST memory.
Hard drive required.
SOFTWARE
AmigaOS 2.04 or higher.
A Macintosh System (boot) disk.
COPY PROTECTION
None.
MACHINE USED FOR TESTING
Amiga 3000/25, 8 MB Fast RAM, 2 MB Chip RAM.
1 internal 880k floppy drive.
Maxtor 213 MB SCSI Hard Drive.
Quantum 105 MB SCSI Hard Drive.
AmigaDOS 2.1
KingCon 1.4 replacing the Amiga Shell.
INSTALLATION
The Macintosh emulation software installs from an 880K floppy disk.
Version 4.5 was the latest 'full' version on disk, therefore I had to
install v4.5 then install the v4.6 patches on top of it. It was quite easy
as both versions used the standard Commodore Installer.
REVIEW
I will be reviewing only the Macintosh emulation software in this
review. The IBM 486DX emulation is suppose to be near completion, but there
has been no release date set, and no one I know has it as of yet.
The Emplant comes on a Zorro-II board that is easily placed inside
any Zorro-II equipped Amiga (A2000/3000/4000). There are four different
versions of the board: a basic one with no ports, one with two Mac serial
ports, one with a SCSI port, and one with both serial ports and the SCSI
port (this one is called the deluxe model). I have the deluxe model, so I
will be be reviewing it.
The first thing you notice when you plug in the board is that there
are two Macintosh serial ports, and one SCSI port on the backplate of the
board (the side sticking out the back of your Amiga). These serial ports
are capable (according to the manual... I have never tested them at any
faster than 14.4k) of transfer speeds up to 230.4k baud normally, yet with
the special Emplant hardware, the speed can be quadrupled (between two
Emplant boards ONLY) to 921.6k baud for AppleTalk (the standard Macintosh
networking) or 460.8k if connected to a DoubleTalk board. The serial ports
are not the standard Amiga RS-232 style, they are the Mini-DIN type. The
second thing you will notice is the large SCSI port. The SCSI interface
uses the 53C80 SCSI chip. It is NOT SCSI-II. It is a standard SCSI-I
controller.
Before you can use your hardware, you must have the 256k ROM from an
Apple Macintosh computer, OR you can copy the ROMS off of a Macintosh that
uses the 256k type. (Note: You MUST own the Macintosh that you copy the ROMS
from, otherwise you could be in violation of copyright law.) A program
included with the Emplant distribution software, called ROMINFO, will dump
the ROMs when run on a Macintosh. In order to get this program to a Mac,
you have to copy it to an IBM formatted disk via CrossDOS and then load it
into a Mac that is able to read IBM disks, or you could use a modem. The
ROMINFO program will dump the MAC ROMs to the same Diskette, and you can now
use that ROM Image with your Emplant. If you opt for the first method
(using the actual ROMs with the board) you must use a program called ROMDUMP
to dump the ROMS onto your hard drive, then you must remove the actual ROMS
from the board. From now on, your Emplant will use the ROM Image that is on
your hard drive. Either way, you will end up with the same image.
Once you have the ROM image, you can start the Emplant and get things
up and running. There are three versions of the software that come with the
Emplant: a version for EC processors (680EC20, etc.), a version for Amigas
with the actual kickstart ROM chips (A2000/4000 and some 3000), and another
version for Amiga 3000's with the softkicked kickstart ROMs. When you first
start the emulation software, you will be presented with a preferences
screen, where a plethora of options are presented to you. You are able to
select the amount of memory that the emulation will use, the screenmode, 24
or 32-bit emulation (more on this later), mouse and keyboard emulation,
sound, etc....
When the emulation first starts, your computer will beep (a la
Macintosh), and should you have a Mac hard disk hooked to the SCSI port or a
boot disk in the drive, the macintosh will proceed to boot. Once you are on
the Mac side, everything runs well.. pretty much like a Macintosh. The only
major difference will be the ejection of the disks. A little symbol will
appear at the top of the screen which means to eject the disk (much like
that of A-Max II+ for those of you who owned it). Aside from this,
everything runs exactly like a Macintosh. One note: Some software is not
"32-bit clean" and will require you to select 24-bit mode in the preferences
screen. 24-bit mode will limit the amount of memory that you have available
for the emulation. I highly recommend you install Apple System 7.1 or
greater, otherwise you will be forced to use the inefficient 24-bit mode.
The graphics speed with my EGS Spectrum is about 50% faster than that of a
standard Mac II when run in 256 color mode. However, in 24-bit mode the
graphics speed is extremely slow (much like 16 color mode on the Workbench
of an ECS Machine). On my Amiga 3000/25, Emplant emulates a Mac IIci, and
on an A4000/40 it is supposed to emulate a Quadra 650(?).
Unless you have a high-density disk drive, do not expect to be able
to read Macintosh disks in your Amiga disk drives (unless you happen to have
an A-Max cartridge and a Mac Drive, or AMIA). Having a high-density disk
drive will allow you to read Macintosh High Density diskettes, but not the
low density variety. To read the low-density (which are fairly rare) you
will need either AMIA or an A-Max Cartridge & Mac drive. (Note: if you
have an A-Max cartridge & Mac drive you will not be able to use then inside
the Mac emulation, instead you have to use an included "converter" program
to convert the disks to EMPLANT format so that they can be used in the
emulation. AMIA is able to read Macintosh low-density disks inside the Mac
emulation).
Multitasking on the Emplant is very good. You can switch to and from
the Macintosh and Amiga Workbench screen. Though if you only have four megs
of Fast RAM you probably will want to disable Workbench to get the most
memory out of Emplant. With my eight megs of Fast RAM, the most memory I am
able to get out of the Emplant is about 5.7 megs of Macintosh memory. You
are able to set the task priority of the Emplant software as high as 0. Any
higher (according to J. Drew) and it would cause the emulation to actually
run slower. According to Xoper, when there is little load on my Amiga side,
the Macintosh Emulation can take up almost ALL of the available CPU time;
however, when I am doing something processor intensive on the Amiga, the
Macintosh side will lower its CPU usage to about 50% or possibly even
lower. I have experienced some crashes while downloading on the Amiga side
at high speed, and doing some other stuff on the Mac. Overall, the system
seems slightly less stabl
