List of DOS-based palmtop computers

This is just my personal list that i made due to my obsession with DOS-based palmtop computers. I like MS-DOS and AA-Batteries - some machines are a bit too large to fit on a palm, but i still included them because i felt fellow collector might like them. I only list x86 compatible machines, so if they can't run DOS I'd normally not include them here. Yeah, so no "Windows CE" or MIPS linux machines, sorry! Also i could include some normal modern netbooks here - i have loads of these, but i try to keep this space reserved for the vintage ones. Maybe I'll make some seperate UMPC list one day, but i usually always lack time.

About "fair use" policy for photos: I have many of the palmtops i listed here - some photos i have been emailed or found them on a website myself, some are from official manufacturers advertisement, but to get this list going I mainly used photographs i did not take myself. I regard this to fall under the "fair use" law. You may have noticed that there are no ads on this site and I am kinda non-profit organization here. I try to provide infos, help and useful files for fellow palmtop enthusiasts. But i will REALLY try to replace them with my own pictures whenever possible very soon, i just lack the time. I already have a half SD card full of photos - many just didn't come out very well and it also requires some time to sort and cut them. Also there are some palmtops i simply don't own myself. If i "stole" your picture and it is not replaced with my own in the next few months then maybe it was the only picture of that machine i could find in the free western world. Please understand that i want to preserve the knowledge about these machines for future generations. If you don't like the idea of "fair use" then let me know (my e-mail and link to my forums are a few paragraphs further down this page), maybe i can buy your palmtop, maybe i can give you another rare palmtop for it or maybe i can just work it off (I am good at programming, repairing laptops, 3d graphics), or i can just get my ass up and take a photo of my own one (if i have it). I am sure we can work something out. So thanks in advance for helping me out by discussing the matter with me first.
There will probably always be some point of discussion about whether a machine should be included or not.
I have included some machines that are probably a big too large to deserve the term "palmtop" or "handheld" still i felt fellow collectors or enthusiasts may be interested in these.
I tried to group them halfway reasonable which may not always be optimal.
The reason i made this list is that i have not found any other source with detailed infos about DOS-based palmtops so it was sometimes hard to find any information at all. This page contains all the infos i could collect. While 99% of the info should be accurate i can not 100% rule out that i make mistakes, message me at hiddenbelow dot com at gmail dot com to report any mistakes or missing models.

So here is my email again (image to keep away spammers):

- Try to put PALMTOP in the subject line.
But i would prefer if you could post in the forums so my spam filter can't eat your mail accidentially.
