Product Support Bulletin Subject: Using Expanded Memory with Equity and Apex Computers Date: Page: 3/2/90 1 of 6 Q1. A. Q2. A. PSB No: Originator: S-0047C KAS ‘/“p& What is Expanded Memory? Conventional memory, managed by MS - DOS, is limited to 640K. In response to the need for greater amounts of accessible memory, the LIM EMS (Lotus/Intel/Microsoft Expanded Memory Specification) was introduced in 1984. EMS, version 3.2, provides usable memory beyond the 640K limit through “bank switching”.
PSB No: S-0047C Page: 2 of 6 Q3. A. Q4. A. Q5. A. What about the 155Mb RAM listed as the maximum for the Equity III +? This larger amount of RAM is the maximum usable memory range for an 80286 microprocessor and generally refers to extended memory. Extended memory starts at the 1Mb boundary and extends out to 16Mb. As it requires a 24 - bit address to access memory in this range, extended memory is handled by the protected mode of the 80286.
PSB No: S-0047C Page: 3 of 6 Q6. What memory expansion boards are compatible with the Equity I and Equity II? A. The following boards have been tested by Epson in the Equity I and II: All Card w/MMU Multifunction Liberty PC Mini Magiccard (EV - 138) AST SixPak Premium AST Rampage All Computers, Inc.

Q11.
PSB No: S-0047C 5 of 6 Page: Q13. A. Are there any guidelines to installing the SlMMs in the Equity 386/20? Yes, when SlMMs are installed to increase memory beyond 1Mb, they must be installed so that banks of SlMMs are installed as matched pairs.
PSB No: S-0047C Page: 6 of 6 Q17. Are there any general guidelines for determining the chip speed to install on the memory expansion boards? A. Yes, if the CPU speed is 8MHz or less, use 150ns RAM chips. If the CPU speed is 10/12MHz, use 120ns RAM chips. Q18. Is there anything that should be kept in mind during the installation procedure for the memory expansion boards? A. Yes, when installing the memory boards in the Equity II + and Equity Ill + (12MHz models), remember that the bus speed is 12MHz.
