The differences between the two models probably have more to do with the particular configuration the customer ordered from Netier. While there have been revisions to the boards used in the SL and XL machines, I believe that the same board was used in the 1000 and 2000 at any given time.
When customers ordered these, they had a choice of:
- CPU speed
- RAM
- Add-on card (on the 2000) such as modem, PCMCIA reader, etc.
- DiskOnChip
- Hard drive
- Floppy
- CDROM
- Operating system
What this all means is that you can never tell what you're going to get when you buy one of these machines.
As far as the blue screens, you may want to check the RAM. If that doesn't clear the problem, try Windows 2000. With 128MB it seems to be very stable.
