Hi. my (ex) wife bought me one of these when they were reduced to £50. It was great in theory but the processor wasn''t fast enough to keep up with handwriting, and the handwriting reader never managed my handwriting. The main problem was unit was driven by three AA cells if I remember right, and the memory wasn''t backed up with a lithium cell so I had a battery failure and lost all the data. As I was using the thing as my diary and contacts list, I lost all my work (needless to say I didn''t have a backup, so it was as much my fault).\
|
||
Losing all my diary entries caused so many problems and so much work to put right I have never since used an electronic diary - only a paper one.\
|
||
After the loss of all my data I never trusted the unit to work and I can''t remember what became of it after that (I probably sold it or smashed it up)

Hi, Diego. I doubt you''ll get this (or care if you do), but I just unpacked an old PDA600 that had been in storage and found that it, too, had that melting problem $ it was like it was covered in honey. Disgusting! I was able to clean it off with rubbing alcohol, a rag, and lots of elbow grease.
|
||
|
||
I suspect the sticky stuff was the rubberized coating it used to have. Once it''s removed, it''s covered with a sort of plain, slick plastic. Good luck!

Like many, I bought one of these from Tandy. It was a great idea in theory, but too flawed in practice. The main problem was that it was just too bulky to carry around!
|
||
|
||
I gave mine to a friend who used it in an industrial setting. There it was great - he hooked it up via serial link for interrogating water treatment plant controllers on-site.
|
||
|
||
If Amstrad had produced a rugged version with some decent comms software and an SDK (and $ped the bundled software, to be honest) they could have shifted thousands of them!

My Penpad seems to be melting....\
|
||
I guess that at some point it was cleaned with some product that should not have been used, and now it's sticky, just as if the plastic material was melting very slowly.\
|
||
Anyone has any sugestions about how to solve this problem?

From the page: "However, Amstrad's approach with the PDA600 was very much more primitive with users only able to input one letter at a time in a box at the bottom of the screen."
|
||
|
||
This is actually incorrect -- that description sounds more like Palm machines. The PDA600's screen was divided into a grid of small boxes, into which you wrote individual characters. So you couldn't write freehand, but you could write separate letters and see them. There was no box at the bottom of the screen, or anything like that,

text: I was given one of these as a gift by my boss in 1994. I loved it and thought it worked quite well, but it was too fragile for me - 6 months after I started using it, i was looking up a number in it while in an airport phone kiosk, and it slid to the floor, shattering the glass screen. I think i still have it laying around somewhere if anyone is interested in the parts.

My Amstrad PDA600 was a completely unexpected christmas gift. I had spotted them for sale in Tandy for 50quid and said how cool thay looked. I received the PDA, 2meg PCMCIA card and leather cover.
|
||
|
||
The text recognition was basic, but did the job once you learnt to write in the style it wanted. My PDA served me well through college and I still have very fond memories of it.\

The year 1993 saw Amstrad release a handheld computer capable of handwriting recognition just weeks ahead of Apple's much-hyped Newton. However, Amstrad's approach with the **PDA600** was very much more primitive with users only able to input one letter at a time in a box at the bottom of the screen.
|
||
|
||
The device was based on a Z80 compatible Zilog Z8S180 microprocessor running at 14.3MHz and memory was expandable from 128KB up to 2MB with PCMCIA cards. Batteries life was 40 hours, from three 'AA' size batteries and the device weighed just 400 grams.
|
||
|
||
Other features included a search function, world time clock with multiple alarms, information transfer capability to and from PCs, metric-imperial conversion and the ability to input drawings.
|
||
|
||
But despite being less than half the price of Apple's more advanced machine – $430 compared to $920 - the PDA600 bombed, although it does seem to have been popular in Germany, for some reason.
|
||
|
||
Cliff Lawson, PDA600 project manager, writes on his [web site](http://web.ukonline.co.uk/cliff.lawson/penpad.htm):\
|
||
The PDA600 is one of my favourite Amstrad projects which probably has something to do with the fact that I was the Project Manager!\
|
||
Unfortunately, The whole PDA concept was a bit of a plot that failed and as we were left with huge stocks of the PDA600 we have recently \[c1996\] sold them all to Tandy (Radio Shack). This does have the huge advantage that you can now buy one for £50 (which is less than half what it cost us to build them!)\
|
||
...\
|
||
Interesting fact number 37 is that we got about 95% of the way through developing a replacement for the PDA600 called the PIC700 that included a radio pager but it ran hugely over budget and schedule and was eventually shelved ... shame, it was brilliant."
|
||
|
||
Those that actually spent money on the PDA600 were less enthusiastic.\
|
||
Mark Stevenson () says on his [page](http://www.markstevenson.nildram.co.uk/com/comppda600.htm):\
|
||
What can I say about the PDA600? This must be in my opinion the worst computer ever! It was supposed to be able to convert handwriting to text to allow quick and easy entries to be made, but it could never read my writing so I was forever going back to correct my mistakes.\
|
||
The machine was also short on memory, it came as standard with 128kb. This could be filled with around 20 free form notes without any database entries being made at all.\
|
||
The database was completely uncustomisable, being suitable really only for a phone book. It also had a diary function which I don't think was too bad - if you could ever get the entry in with the handwriting recognition.
