EPSON EPSON AMERICA INC. SERVICE DEPARTMENT PRODUCT SUPPORT DATE: 6/8/87 NUMBER: S-0012 SUBJECT: EPSON EQUITY ENHANCED KEYBOARD COMPATIBILITY The purpose of this bulletin is to provide information regarding the compatibility of the enhanced "AT" style Equity Plus series keyboard with the Equity family of computers and a general statement on software support. With the introduction of the Equity It and III+, Epson brought out an enhanced keyboard design - very similar to the enhanced keyboard introduced by IBM on the Model 339 AT. There are a couple of areas to make note of. 1. Keyboard Compatibility The enhanced keyboard cannot be used on an Equity -'I, II or III. The enhanced keyboard (as with IBM's) requires explicit ROM BIOS support. The Equity It and Equity III+ incorporate this support; the earlier machines do not. It is possible, however, to use a third-party "enhanced-style" keyboard (such as the Datadesk Turbo-101) which offers switch selection for PC/XT or AT usage. (Please note that early versions of the Equity I and II did not support any third party keyboards.) The correct jumper settings for non-Epson keyboards are: Equity I: Equity II: J2 and J3 jumpered J 3 , J4 and J5 set for position 1 Also note that once the above jumper changes have been made, attempting to use the Epson keyboard will result in damage to the keyboard-and main board. 2. Software Compatibility Not all applications "know" about the enhanced keyboard. The scan codes and mapping are subtly different. If you experience difficulties with certain applications (particularly any that re-program the keyboard), contact the software vendor and ask about enhanced keyboard support. Page 1 of 1
