I recently bought 4MB FlashRAM card from Pretec Electronics. They are at I ordered directly from their site. Costs $89
!. It needs _NO_ special drivers.
2. It does _NOT_ have any delay at all.
3. It has 3.3MB space when it is formatted by Ogo Transfer utility which
creates the directory structure.
4. It takes ~60 mA when active and ~10 mA when Ogo is on but idle.

Here's the table, currents in mA. Omnigo 100.
no card SRAM Flash RAM
Premax 1MB Pretec 4MB
Off 1 1 1
Idle 70 80 80
Running 220 300 280
Writing 220 300 440

5. I'm delighted with all the space I have now. I don't take the card
out anymore. I've rearranged Omnigo desktop, I've installed GeoManager.
I've installed DOS from Geos option. I've even installed Wyndmail and
Ogo Draw allthough I haven't use them at all.

6. To add to all those battery discussions. I am currently using Varta
NiMH 1100 mAh rechargeables which last 5-8 days / 250 minutes, FlashRAM
allways inserted, rare communication.
