OSS Integer Basic ; Copyright (C) 1983-1986 by Stephen D. Lawrow & OSS, Inc.#

From Tomasz 'KrOtki' Krasuski from AtariAge:

I've used MAC/65 1.02 to assemble it to cartridge. It requires changing lines 130 and 150 in D1:MASTER of the source code, to change both PROM and _CART to 0. Then assemble from disk, which results in a binary file that loads to $3000-$6fff, bank order "3M04". Retrieve this data in an appropriate order to create a ROM image.

So, Integer BASIC appears to contain the same features as BASIC XE, but with integer arithmetic. And it's blazing fast.
