BRIEF DESCRIPTION
A hardware Macintosh emulator which runs concurrently with AmigaDOS.

LIST PRICE
I don't know the list price. I paid $300 for Emplant with
Appletalk. There is a version with SCSI as well, and a version with neither
Appletalk nor SCSI, but I'm not sure of their prices.
SPECIAL HARDWARE AND SOFTWARE REQUIREMENTS
HARDWARE
An Amiga 2000 or 3000 with a 68020 or 68030 processor.
(68040 compatibility is unconfirmed, A4000 support is
promised "soon", and an A1200 board is in the works.)
MAC II/IIx/IIcx ROM's.
SOFTWARE
Macintosh System 6.0.5 or greater
COPY PROTECTION
None.
MACHINE USED FOR TESTING
Hardware: A3000/25, 2Meg Chip RAM, 4Meg Fast RAM.

Emplant MACII v1.7
AmigaVideo v2.2
REVIEW SCOPE
I have decided to write this review as a summary of where this
product currently stands in development. The product is quite usable, and
features that are planned for the near future will make it quite complete.
I am not associated with Utilities Unlimited, (except maybe as an
unsolicited beta-tester) and have no financial interests in the product's
success.
OVERVIEW
The Emplant emulator is a hardware/software combination that allows
the use of an 68020/68030 powered Amiga to run an environment almost
identical to that of a MAC II/IIx/IIcx. (68040 compatibility is
unconfirmed). The hardware can support Appletalk and a SCSI interface
depending on configuration. The software currently supports hard drive
support, up to 16-color 640X400 emulation, and it co-exists favorably in the
multitasking environment of AmigaDOS on its own screen.
REQUIREMENTS
The emulator requires MAC II/IIx/IIcx ROMs and System 6.0.5 or
greater. It currently ships as a Zorro II card for the A2000 or A3000
computers. A4000 compatiblity is "soon" and an A1200 board is in the
works. You have the option of using Chip or Fast memory, but I would
suggest using Fast RAM and plan on having A LOT of it.
BACKGROUND
I have been caught up in the Emplant fervor since the product was
first vaporware in early 1992. Having waited over six months for the product
actually to ship, I had allowed my expectations to become a little overblown.
Hence, when I finally received my Emplant board and associated software
(especially after at least a week of panic that Utilities Unlimited had
closed up and headed south), I was inclined to give up in dispair together
with quite a number of co-patriots in the Usenet community.
Since the Emplant board first shipped, the software has gone through
quite a few changes. After downloading what must be my 6th or 7th upgrade
from the Utilities Unlimited BBS, I can finally approach the product as a
functioning entity (although not a complete one). Version 1.7 of the
Emplant MACII software now runs at speeds comparable to a true MAC II.
Although it still lacks sound, Amiga printer support, and a conventional way
of supporting MAC low-density disks, it can now stand as a usable substitute
for the real thing.
PRODUCT SUMMARY
Functional in Emplant version 1.7 software:
o MAC II/IIx/IIcx ROM compatible (required)
o Uses all 32bit memory on A3000 and some accelerators (VXL at
least)
o Hard disk compatible, currently only formats up to 20Meg
partitions, but can read any size partitions if
formated by another MAC entity (ie. AMax). Removable hard
drives supported.
o RAM disk supported; (all track oriented AmigaDOS devices are
supported)
o Appletalk printer/network supported (I haven't tested this)
o Disk formats supported:
AMax: Amiga drive compatible, used by AMax II/II+ Mac
Plus emulator by Readysoft, custom.
Emplant: Amiga drive compatible, claimed to be faster
than AMax format, custom.
MAC (low density): Uses additional hardware called
SYBIL (sold by Utilities Unlimited) to read
on Amiga drives. I've had no luck with SYBIL.
o Amiga video supported using a chunky pixel to planer conversion
program. This program copies MAC graphics (stored using a
method incompatible with the current Amiga custom chips to a
displayable form in an Amiga intuition screen. Video update
rate for this conversion can be set by the user from 6 frames
a second up to 60. I have found 30-60fps very smooth and have
not suffered a significant slowdown in MAC system performance.
Modes currently supported:
Black and White (1 bit) (very fast)
4 color (2 bit) (very fast)
16 color (4 bit) (slower, but usable even at 60 fps
video conversion rate)
o Multitasks with AmigaDOS; allow a foreground and background priority
based on whether or not the MAC screen is activated.
o Support for 32bit Quickdraw.
o System 7.0.1 & 7.1 support (I haven't tested this either)
o Appletalk serial support from an AmigaDOS driver, so you can use
the Appletalk port as a second serial port.
o Noclick for Amiga drives
NOT functional in version 1.7 software, but forthcoming according to
the author:
o Disk formats not supported in this version include IBM (low and high
density) and MAC high density, slated for next software release.
Also, an AMax drive interface is claimed to be forthcoming.
o Amiga parallel printer/serial support from MAC side.
o Mac sound support.
o AGA mode support, all graphics modes, up to 256 colors.

Note: The system really bogs down in 16 color mode on an ECS machine.
This is due to DMA contention and is a result of the Amiga hardware
and not the emulation as such.
FINAL NOTES
o The emulator requires a program added to the start of the
s:startup-sequence. This program reboots the machine the first time
it is run, and then patches some system vectors when ru
