| Hardware |
Late model XEN-i 286/30 and VX WS with IBM EECO 102
Keyboard.
XEN-S range until December 1989.
Qi range until December 1989. |
|
| Software |
Various applications, Excel, Supercalc V, Wordstar. |
|
Symptom Keyboard locks up during software package
operation. Extra 2's and 8's are added to text during use of optional arrow keys. Shift
and Alt mode are locked on during operation of application. |
|
| Cause |
The major cause of this problem is the version on firmware
in the keyboard. EECO have issued a number of different versions. Any below 107 can cause
one of the above problems. Versions - 096, 098, 102, 107. |
|
How to identify the version of keyboard. |
|
Any product shipped before 1st December 1989 will have a
firmware version pre 107. By removing the rear cover of the keyboard, locate ICU1 and use
the identification code on top of the IC to determine which version of the firmware is
fitted. |
|
MS 0324096 = 096 |
MS 0234102 = 102 etc. |
|
The following item will also have to be checked: MSCALC.SYS
is replaced by ANSI.SYS and KEYB.UK. |
|
| Cure |
Check the configuration and versions installed, and install
ANSI.SYS and KEYB.UK where necessary. |
|
Upgrade the keyboard to version 107. This action will
resolve the majority of the problems. Where problems persist also check the following: |
|
Windows and Excel: check the version of Windows is 2.11 or
later. Wordstar 5: ensure the keyboard rate is adjusted (see Technical Bulletin P 2.5.13).

| Issues |
XEN-S with Supercalc and above memory drivers: there is one
outstanding problem with this configuration, which is where the numeric keys are used for
cursor control, 2's 4's 6's and 8's can be left in the spreadsheet when moving between
cells. To overcome this problem the free of charge memory drivers AEMM386.SYS and
EMM386.SYS have to be replaced by QEMM.SYS at a RRP cost of £80. |
