Palm Pilot Personal -> Palm III
===============================
Now I have a working Palm Pilot Personal with the "Palm III" upgrade.
I wasn't that easy: I spent lot of time in searching of a Palm Pilot
with a stylus (it differs from the later Palm III stylus which I have
plenty of) and a complete battery doors. The stylus was an easier part
of problem. To find the undamaged doors was much harder. I even got a
Palm which is working but has no battery doors at all.
At the end I have got at least 4 (four!) Palm Pilots (1 Professional, 2
Personal, 1 IBM Workpad). The Workpad (internally it is a Palm Pilot
Personal) is the most complete (it seems to be almost unused, actually)
but it is black so it would be cruel to replace its nice black memory
doors which a gray ones (I have had to replace them because the upgrade
includes an IR sensor which cannot fit under the original doors).
Of course I wanted to use the Palm Pilot Professional because it is the
only one which has been made in the USA (the rest is from Malaysia and
other countries). But it does not work. It looks like it suffered a
battery leak in the past).
So finally I have selected one of the Palm Pilot Personals. It put the
stylus from in the place (it fits and it holds here) and the battery
doors, too.
Then I removed the battery doors. The original Palm Pilots up to the
Palm Pilot Professional have a memory card here. In the case of my P.
P. Personal there was 512 kB of memory.
I have got a product called "Palm Pilot 2MB upgrade" which is a card
with not only a a 2 MB memory chip but also a flash memory with an OS
(the Palm OS 3.0) and a infrared device. So I put this instead of the
old memory card). Then I applied the new memory doors. They are a bit
bigger and include a small transparent window for the IR device.
And that was all - now I have machine which identifies itself as the
Palm III with 2 MB of RAM! OF course there are differences - its dock
connector differs from the Palm III one so it cannot use no dock nor
peripherals designed for the Palm III. But I can live with that. On the
other side, all Palm III-compatible cases were in fact designed for the
older Palm Pilot series so they fit both.
Now I have to make few pictures and put them here or in my blog...
