The memory issue would be easily solved by making a module that accepts compact flash cards. These cards are fairly reasonable in price because they are not proprietary, and any user could get the amount of memory to suit his/her needs.

The only problem is that the Moterola Dbz chip in the visor is only made to handle up to 16 megs of ram. You'd also need to include a chip that can control the memory.

The trgpro can use the 340meg ibm microdrive; 324 megs more than the 16 that you are talking about.
I think they have already solved that piticular problem with the dragonball ; It is simply a matter of implimentation.

Remember the old days, with DOS, where you bought a new 140M drive and split it into a bunch of 10-20M partitions because the file system could only deal with them that small?

I'll bet that's what TRG's doing.

remember the old days when you spent $450 for 8 megs of ram on your desktop??

i'm glad we're not there anymore

Actually, it shouldn't be that difficult. All CompactFlash cards really are, are small ATA hard drives. That's why you can mount one in a PCMCIA slot on a laptop, fire up Windows and have it as Drive D.

All you have to do is to get a controller IC to do access the CF card, plus a piece of PalmOS software that will allow you to access the CF. A friend told me that the way the TRG pro guys did it is by some means to offset the initial memory block. They also might use a different file system scheme (such as grouping the memory as clusters, and remapping the clusters to memory addresses) because the largest file size that the TRG Pro can access is larger than 16Mbs. Can anyone confirm it?

(And, on an interesting note, ever tried installing Win NT on a laptop while the CF card is plugged in? It'll try to dump the swap file onto the flash card because it's the fastest "drive" in the system as far as seek time goes 8-) ).

as I recall from the FAQ of the MiniJam module, you can use the memory in the MMC cards (which come in 16,32, and soon 64) for palm apps and data as well as MP3s. and there are two slots, so it would be possible to have 128 megs of memory.
