|An ATA flash card will sometimes do it but, as I recall it's a little involved. There are still a couple of Itronix groups on Yahoo where you'll find a lot of help and files.|
If you have a 6000, it uses a Viper 1.8" pcmcia hdd...either the 260 or 340Mb flavor. 6250's use a 2.5" hdd.
You can pull the drive, plug it into a type III pcmcia slot on any DOS machine. Fdisk, format and sys the drive. Make a DOS directory and expand the files from your 6.22 disk into that directory.
These things aren't real easy to take apart and reassemble...all screws have loctite and you'll need quality torx drivers to work on that thing. Most screws are T-10 or T-8. Insure all "o" rings etc. are in place when you reassemble the machine.
The 6000's come with either 8 or 16Mb proprietary memory and a SLC50 processor. The 16Mb models do a pretty good job running 95 and IE 5.5 but, I recommend you stay with DOS and 3.xx. Pen Computing for Windows is installed on the touchscreen models.
The only reliable external floppy is the Accurite but at about $60US just ain't worth it for a 20 buck laptop.
If you get it working, you'll like the greyscale screen...perfectly visible in direct sunlight. Will it survive a drop onto pavement? Yep. Can you use it in the rain? Yep again...hail storms too. Good little machines but don't spend any real money on the 6000 or the nonpro 6250.
