Hi everyone,
As some of you know, it's possible to use Compact Flash cards with a CF to PCMCIA adapter on the HP 100 and 200LX palmtops.
But, beyond a certain size (I think it's 256MB), the cards don't work.
There exists a driver called acecard3.sys, which, when added to the config.sys, will enable the use of larger cards, up to 2GB.
Unnfortunately only very few cards work with this driver.
I have purchased approximately 7 different brands of cards of 1GB and 2GB and only one of these worked,
it was an "Advantech SQFLASH Industrial Grade 2GB" card.
All the other brands/types don't work. (I use them with my Psion Series 5mx instead, and they work fine on that machine).
Here's a link to an old webpage which has a list of working cards:
http://bmuessig.eu/using-cf-cards-in-the-hp-100lx
Now, you'd think you can just buy a SanDisk 2GB as shown on that list and expect it to work, but,
I have bought 4 different cards, all old SanDisk 2GB cards and none worked.
I tried to make sure they weren't Chinese knockoffs when buying (making sure they weren't shipped from china),
but it's impossible to know for sure as I don't have a reference card that I'm sure is authentic.
I even bought another 2GB Advantech SQFLASH card and it did not work, so I assume it's probably a fake card.
So, my question, what makes the few cards that DO work so special ?
Is there a way to test them ? Maybe with some kind of advanced diagnostic tool that can show technical details about a specific card when attached to your PC ?
There must be some kind of difference between the working ones (only a select few, I've found only one card) and those who don't work (most cards).
I'd love to hear from anyone who can illuminate on this...
Thanks for your time,
Radiance
