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: 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.

These programs are available from the Epson America Inc.
FOR EQUITY I: COMPOSIT.BAT - Modifies DU.EXE, SETUP.EXE, ARCHIVE.EXE and HDSIT.EXE to improve the brightness of messages when using a composite monitor. GOLDCARD.BAT - EQRAMDVR.SYS - For those RAM DISK utilities which need it, an "empty" space disk drive is created. (See pages 6 and 7 for instructions on installing and using this file.) ROMPATCH.COM - Equity I systems with ROM BIOS versions earlier than 2.
FOR EQUITY II ROMPATCH.COM - Equity II systems with ROM BIOS versions earlier than 1.11 will require this patch to increase the stack space in order to run certain application programs (Lotus 1-2-3 Version 2, for example). (See page 9 for instructions on installing and using this file.) MODE.COM - The supplied version of MODE did not function properly when used to switch from color to monochrome display (MODE MONO); this version does. MODE.COM is a modified version of the Equity II MODE utility.
EQUITY II PATCHES HGC.COM (continued) - Epson utility which allows the use of Hercules monochrome graphics. (See page 8 for instructions on installing and using HGC.COM. PSHERC.COM - Allows Print Shop to run in Hercules graphics mode. Run PSHERC.COM before loading Print Shop. EGAN-PAT.COM - Allows use of Honeywell's PC VIP terminal emulation software. HERCDUMP.COM - Allows screen dump in Hercules Graphics mode. It is a memory resident program used in conjunction with GRAPHICS.

ROMPATCH INSTALLATION INSTRUCTIONS Some Equity I and Equity II computers have trouble running certain application programs (Lotus 1-2-3 Version 2, for example) because they have an early version of ROM BIOS. This diskette contains a patch named ROMPATCH.COM which either corrects the problem (by patching the ROM) or tells you that your computer does not need it.
