Anyone programmed a PIC16F84A for Linistepper?

Information on the website for Linistepper, (a microstepping stepper
kit) states that the PIC software can be programmed into a PIC16F84A.
The ASM code to do so is available freely for download. See:

http://www.piclist.com/techref/io/stepper/linistep/index.htm

However, two people I know have tried to compile the .ASM file for the
16F84A and failed, due to memory related problems as I understand it.

Has anyone succeeded in putting this program into a 16F84A? Is the hex
file available somewhere? Or is this impossible to do?
