-
The T3100e had a 12 MHz 80286 CPU, 1 Mb RAM and a 20 Mb hard drive.
-
The T3100e/40 was the same as the T3100e, but with a larger 40 Mb hard drive.
-
The T3100SX had a 16 MHz i386SX CPU, 1MB RAM and a 40 Mb or 80 Mb hard drive, and also included an internal rechargeable battery for true portability.
