The 68040 Productivity Solution: The MicroMac 68040 LC475 Logic Board Upgrade is MicroMac's solution to upgrading 68020 and 68030-based LC and Performa Macs with the ability to run the latest application, multimedia and Mac OS software. Featuring either a fast 50/25MHz or 66/33MHz 68040 processor, the MicroMac 68040 LC475 Logic Board Upgrade delivers dynamic speed and microprocessor technology. The upgrade provides such features as:

• 50/25MHz or 66/33MHz 68040 processor with or without FPU
• 32-bit data bus
• Base RAM of 4MB expandable to configurations of 5, 6, 8, 12, 20 or 36MB
• VRAM configurations of 512KB (8-bit or 256 colors) or 1MB (16-bit or thousands of colors)
• Integrated Level-1 Cache
• PMMU (Paged Memory Management Unit) built into 68040
  (PMMU is required to run Virtual Memory or RAM Doubler)
• 114-pin LC style PDS slot for third party PDS cards (compatible with 96-pin LC-style PDS cards)
• Built-in ports for Video out, Printer, Modem, SCSI, ADB, Audio out (stereo) and Audio in

Optimize Your Performance: You receive all the benefits, features and advanced power of 68040 software with the MicroMac 68040 LC475 Logic Board Upgrade. With the 66/33MHz upgrade model you'll get a performance gain of up to 450%. Imagine faster access to the Internet, Web sites and your applications. Enjoy quick screen redraws in Photoshop and other graphic-intensive applications. Scroll through your word processing documents in mere seconds instead of minutes. The 68040 processor delivers the power needed to run today's demanding software that will not work with 68020 or 68030-based Macs - even those equipped with an accelerator card.

RAM! RAM!! RAM!!! And More RAM: No longer are you limited to the 10MB limitation set by the LC and LCII. Give your applications room to breath by adding up to 36MB of RAM onto the logic board*. You even have the advantage of using Virtual Memory or RAM Doubler and TRIPLING your RAM capacity up to 108MB! (Ram Doubler 2 required.) That's more than enough memory to run all your favorite applications, Internet software and utilities as well as the latest Mac OS 8 in a comfortable computing environment.

*Note: 72-pin SIMM required. LC and Performa models, excluding the LCIII and Performa 450 and 460, utilize 30-pin SIMMs. If you wish to use your 30-pin SIMMs you will need to purchase the $19.00 MicroMac SIMMchanger Memory Upgrade product.


No More Grainy Dithered Color Images: The MicroMac 68040 LC475 Logic Board Trade-up provides you with the ability to run 16-bit color (thousands of colors) on monitors up to 17" or 8-bit (256 colors) on monitors up to 21". Now you can view rich, pure photographic color images on a large 17" monitor in such applications as Photoshop and Web browsers displaying JPEG images. With 16-bit color you can do accurate color correction on photographs, scans and images that is impossible to do with limited 8-bit color or on small cramped monitor displays.

The video output of the LC475 requires that you populate the LC475 logic board with two VRAM SIMMs. You can accomplish this by removing the one VRAM SIMM installed on your LC or Performa computer and installing it into one of the two VRAM sockets of the LC475. You will then need to add an additional VRAM SIMM of the same size to the second VRAM socket. For example, if you have a 512KB VRAM SIMM installed on your LC or Performa computer, you must get a second 512KB VRAM SIMM in order to get correct video output from the LC475.

You can identify the VRAM output of your current LC or Performa computer by the following procedure:

• You have a 256KB VRAM SIMM installed if you have 256 colors on a 12" monitor or 16 colors on a 13" monitor.
• You have a 512KB VRAM SIMM installed if you have 32,768 colors on a 12" monitor or 256 colors on a 13" monitor.

The chart below identifies the video output support of the LC475 and the required VRAM SIMMs needed to drive the number of colors on various monitor displays:

High Fidelity Stereo Output: Enjoy stereo FM-quality output from your Mac instead of muffled mono AM-quality sound. The MicroMac 68040 LC475 Logic Board Trade-up incorporates an audio-out port that drives stereo sound on external speakers, amplifiers and headphones. It's perfect for delivering exceptional music and sound effects from the latest multimedia games that require 68040 or better Macs. Your current LC or Performa computer provides only mono sound output, which is far from delivering the rich and dynamic range of music and sound that stereo delivers.

Room for Expansion: The MicroMac 68040 LC475 Logic Board Upgrade provides a 114-pin LC style PDS slot that supports the addition of an Ethernet, video capture, Apple IIe emulation or other third party PDS card as well as any 96-pin LC-style PDS card. The PDS slot provides you with the option to build a Mac system that is best suited for your computing requirements.

You even have the ability to enhance your MicroMac 68040 LC475 upgraded LC or Performa computer with the MicroMac LC/LCII Power WorkStation. The workstation is a chassis extension that upgrades the case of your computer with the ability to incorporate an internal 5.25" drive (such as a CD-ROM, Jaz or SyQuest drive), an internal 3.5" drive (such as a Zip or Optical drive) and two additional hard drives.

System and Tool Requirements: LC, LCII, LCIII, LCIII+, Performa 400, 405, 410, 430, 450 or 460 with appropriately installed System 7.1 or later software and optional anti-static grounding strap (available at most computer hardware stores).

Upgrade Installation: Prior to installing the MicroMac 68040 LC475 Logic Board Upgrade you will need to update or reinstall the System 7.1 or Mac OS 7.5 - 8.0 software so that it is compatible with the LC475. This is a simple procedure that is outlined in the documentation that comes with the LC475 upgrade. Once you have the correct System software installed, the installation involves removing the current 68020 or 68030 logic board from your computer (which easily unsnaps from the inner case) and installing the LC475 logic board. If you own the original Mac LC computer, you will need to also purchase and install the MicroMac Fan &Speaker Upgrade Kit. (The original Mac LC fan and speaker do not fit with the upgraded LC475 logic board.)
