EPSON Product Support Bulletin Subject: Proper Method for Running Benchmark and Diagnostics Programs Date: 06/04/93 Page(s): 1 of 1 PSB No: S-0158 Originator: MWT This bulletin describes the proper method for running any benchmark or diagnostics programs. This applies to any computer system. In most cases, the computer should be started using an MS-DOS boot diskette that’s ‘clean’ - in other words, one with no CONFIG.SYS or AUTOEXEC.BAT files.
EPSON Product Support Bulletin Subject: Equity Series SIMM Compatibility Date: 12/4/91 Page(s): 1 of 1 PSB No: S-0136 Originator: JAD Due to the influx of third party SlMMs on the market, there are some that are not compatible with Epson products. This bulletin is intended to be an aid in ensuring that only compatible SlMMs are chosen for use in Epson’s Equity Series of computers. The SlMMs in question were SEIMENS, CUMULUS and KINGSTON.
EPSON Product Support Bulletin Subject: The Equity 386SX PLUS Diskless Workstation - lnstalling Optional Equipment Date: 3/7/91 Page(s): 1 of 3 PSB No: S-0134 Originator: APA WORKSTATION INSTALLATION SUMMARY Install an 3 or 16-bit network interface card (NIC) with a auto-boot ROM in an option slot. Load the remote workstation boot files onto the file server. Typically, this is done at another attached workstation, using a floppy drive to load the necessary boot files.
PSB No: S-0134 Page: 2 of 3 FLOPPY DRIVE INSTALLATION (continued) Use the write-protected cable if you do not want users to be able to write data to any diskette inserted in the drive. This cable prevents users from copying data from the network server (or any other drive they can access) onto a diskette in either the A or B drive. If an attempt is made to write to a floppy diskette, a ‘Write protect error” will occur.
PSB No: S-0134 Page: 3 of 3 OTHER CONSIDERATIONS If you desire access to the local hard drive while using the network, ensure that the DOS downloaded from the file server can support the local hard drive partition(s). For example, if a large 4.01 MS-DOS primary partition (>32MB) is present on the local hard drive, and 3.30 DOS is used to boot from the file server, the local hard drive will be inaccessible. (An error similar to “Invalid drive specification” will occur when attempting to access the drive).

EPSON Product Support Bulletin Subject: Equity 386SX PLUS Questions and Answers Date: 4/3/91 Page(s): 1 of 9 PSB No: S-0131 Originator: DS/MT GENERAL: Q1. What microprocessor does the Equity 386SX PLUS use? A. The Equity 386SX PLUS utilizes the Intel 80386SX-16 microprocessor. Use of this CPU gives you 386 performance and compatibility in a 16-bit based computer architecture. Q2. At what speed does the Equity 386SX PLUS operate? A. The Equity 386SX PLUS operates at either 16MHz or 8MHz.
PSB No: S-0131 Page: 2 of 9 Q3. What is the Auto Speed function? A. The Equity 386SX PLUS is capable of operating at 16MHz or 8MHz. Some copy-protected applications require the computer to run at 8MHz while accessing the program diskette. By enabling the Auto Speed function, the computer automatically switches to 8MHz when accessing the diskette drive. It then switches back to 16MHz for optimal performance. See above procedure for setting the Auto Speed function. Q4.
PSB No: S-0131 Page: 3 of 9 Q9. Can any other Equity keyboards be used on this machine? A. Only the Equity le. Both the Equity le and the Equity 386SX PLUS use the PS/24-type mini-DIN connector. All other Equity keyboards use the AT-type fullsize DIN connector. Q10. What is the logical assignment of Diskette Drives? A. When the Equity 386SX PLUS is configured with two diskette drives, it will boot from either diskette drive.
PSB No: S-0131 Page: 4 of 9 NOTE: The diskette drive types shown in AFDD message vary with the types of drives installed. If another type of diskette drive is installed (360 KB or 720 KB), the message is adjusted accordingly. Q11. What terminal emulation boards are compatible with the 386SX PLUS? A. The following products have been tested and approved: 3278/79 Emulation Adaptor IBM 5250 Board IRMA/2 SDLC IBM IBM DCA inc. IBM Q12. Does the 386SX PLUS have a battery for the Real Time Clock? A.
