> SL-5500 Memory Limits?, What are the limits on SD/CF memory

This is a bit of a Newbie question, so apologies if I should have posted it elsewhere.

I've just bought a second-hand SL-5500 with a 64MB SD card and a 32MB CF card.

I would like to expand the system memory/storage considerably but I'm not sure what limits there are on the size of SD/CF memory I can use. I don't want to spend lots of money on cards if (a) the Z can't use them at all or (cool.gif the Z can only address a small part of them.

I contacted Sharp Service and was told that the limits are 128 and 192 for SD RAM and CF RAM respectively. I presume that these figures are in MB and only apply to memory (RAM/ROM) rather than storage (disk) devices.
However, this doesn't seem to stack-up with various comments I've read on the ZUG mailing lists and other places, which seem to indicate that people are using up to 1GB SD card and 512MB/1GB CF cards and also using up to 4GB CF microdrives. unsure.gif

Is there a FAQ somewhere which details what the limits are (if any) and what devices do/don't work with the Z?

Many thanks in advance,

John (slightly confused but fascinated with the idea of Linux of a handheld!)

Thanks for the help Mitch and Tumnus.

I don't quite understand Sharp Service's comment about the limits for SD and CF cards (perhaps the limits are what they are able to supply).

Sorry about the confusion about use of 'RAM' instead of 'memory' - I used the same terminology as Sharp's reply. Both SD and CF cards are strictly speaking Flash ROMs (at least as I understand it).

Anyway, as the limits seem to be imposed by the filing system used, rather than any hardware issues (e.g. partial address decoding within the Z), I'll go ahead and upgrade the SD and CF cards as much as I can within reason/budget.

Thanks again.
