The Flashdrive is a portable hard drive like all the other portable drives on the market, except it's smaller, lighter, faster, approved by everyone and costs less. The Flashdrive 25 is only 1.5 lbs and is only 1.5 X 5 X 5 inches. You can run it off of the internal rechargable nicads which are included at no extra charge. If you are near an AC outlet, you can also run it off the AC Adapter/Charger as well. The unit is IDE and thus less expensive than SCSI type interfaces. If you are just looking for extra space to put and run files from, why spend all that extra money. My 40MB Flashdrive 25 starts at $499.00. In fact I have been getting Referrals from Tandy HQ in Texas. We are compatible with ALL TANDYS providing they have a standard parallel port. I know some Tandy Laptops had a edge connector. If you can find a cable for this, it works. Our driver takes 3K of RAM and may be loaded high with DOS 5.0. MUCH LESS THAN THE TRANTOR/TULIN model drives! Flashdrive Requirements: DOS 3.0 or higher. A Standard parallel port. 3K Ram for Driver 5 minutes to get drive up and running. The install program takes 2 minutes to run and you are running the Flashdrive. You can not boot with the Flashdrive, but once the floppy is done loading DOS, you can switch over to the Flashdrive and away you go. Dan Shearer BSE Company 602-527-8843
