New to HPC, have already gotten a lot of good info from folks (got a nic card off e-bay and got it to work well, thanks!)

Anyway, I'm getting ready to buy a Compact Flash card for my J680, how large can I go (not theoretically, but maybe some actual users with actual brand/size recommendations)

Also, can/should I install everything to the Compact Flash, other than the OS...is that possible? I can run everything ('cept updates to the OS) from the flash card? Programs etc... leaving the majority of my RAM for performance?

Anyone had any success with the USB to IRDA adapters? I don't have a serial sync cable, or built in IRDA on my home pc or my laptop, so I was thinking the USB to IRDA would be the way to go since it would have more applicable value then the serial sync, and I can pick one up on e-bay pretty cheap.

I'm sure I'll have more questions, but for now I guess that is it. Unless someone has invented a PCMCIA sound card with headphone jack that works with the J680...and I know that is a pipe dream.

Thanks in advance

Wlecome to the world of H/PCs. I hope you'll be with us for a long long time

The absoloute maximum storage device size that 2.11 can handle is 32GB. As no such card exists, you wont see a problem. From a personal recommendation stand point. I would keep it under 1GB, and certainly under 2GB. Given the price of the things and their R/W operating life expectancy, they're just too expencive for any higher. You also have to consider how unrelaible FAT32 is.

As for installing applications. I would say that 90% of apps can be run from CF. Around 75% will still work after a hard reset. Others you will need to reinstall from the CAB. With such applications, I keep the cab on the CF card, and flag it read only. Under 2.11 this will stop it from deleting after install (note for 2.00 users, this doesn't work). There are always problem applications though such as textmaker and planmaker that will require reinstall from a Host.

I've never used a USB adapter - I have used the legacy Com 3 dongles and built-in PC / Laptop ports. I don't see any reason why the process would be any different. In fact probably easier because you don't have to dos about with COM assignments. Do remember though that while USB adapters may be 4mbps, the HPC will only throughput at 115.2kbps.

... no, that is a pipe dream. Although I have seen a web site in recenemt months made by a Japanese fellow, which shows how to add one should you be electronically capable.

To add to what C' was saying also rremeber the larger the memory the more power tit takes to run, hence shorter battery life.....If you have upgraded your internal memory to 32mb's ( maxium internal ram expantion for the J680) and then run a 512 cf card....kiss that battery life down to about 2 hours or less...i know i use to have a 680 w/ expation & a 690 , with that set up...Steve

I'll probably look at 256 to start, as I am not upgraded to 32.

Begs the question....know of a good place other than e-bay where I can get one of the 16 MB ram upgrades? I posted a request in the trade forum here.
