Free42 is a complete re-implementation of the HP-42S calculator and the HP-82240 printer. Free42 was written from scratch, without using any HP code. You do not need any ROM images in order to use it, yet it is fully HP-42S compatible. Update Description:
- ASTO IND ST X was broken; instead of storing the first 6 characters of the ALPHA register into the register or variable pointed to by X, it stored them into the variable pointed to by the first six characters of ALPHA itself. Fixed.
