Psion 3a with keyboard
======================

My workstation-style PSION desktop is almost complete. I have connected
the PS/2  keyboard to  it. I do  have a necessary  interface (ist  is a
rather big black box  which can run on 9V battery;  it is labelled "KRB
DESIGNS PSION  INTERFACE MODULE").  I also have  a relatively  tiny and
low-power PS/2 keyboard  (I might try the  IBM type M, too  but it will
reportedly require external power source for the interface).

Aside of  it I  can also  connect the  floppy drive.  It uses  the same
connector so it is probably not possible to use both device in the same
time (I'm not  sure as the keyboard interface had  a second serial port
which may be used  to connect the floppy - of  course the keyboard must
be turned off  when another device is connected). It  is also necessary
to stop  the keyboard  driver program before  the floppy  is connected.
Otherwise  the floppy  drive  will not  work and  the  OS will  produce
strange warnings ("drive is write protected", "device is unformatted").

The F1 key returns to main screen and the F10 opens the Menu. The F4 is
Time application and  the F7 opens the calculator. I  am curious if any
of these keys represents also the PSION button.

I am  writing this text on  the PSION with and  external PS/2 keyboard.
It's much easier than use of  the build-in keyboard (which is very good
for a portable device)

It works rather well.  My main problem is that I  don't remember how to
connect the external charger (there are 2 holes labelled 'Power').

Oh, I have got an old 9V battery and it is empty now... :-(


It's funny stuff anyway.
