HEPAX program and PowerCL not compatible on 41CL?

[mfleming]

Here's a working configuration with the regular versions of the Extra Functions library and the PowerCL Utilities.

Code:


Port         Page  ID    XROM    Description
System        4    4LIB  N/A     Library 4
Printer  P    6    HEPX    7     HEPAX 1D
HP-IL    H    7    PWRL   12     PowerCL Utilities
1       1L    8    HEPR    8     HEPAX RAM
        1U    9    HEPR    9     HEPAX RAM
2       2L   10    HEPR    -     Reserved
        2U   11    HEPR    -     Reserved
3       3L   12    YFNP   15     Extra Functions Plus
        3U   13
4       4L   14
        4U   15

I used a modified version of the YPOKE commands from the CL41 Calculator manual to initialize the two HEPAX RAM pages. The Prev and Next Page pointers were adjusted for pages 8 & 9. Since the serial interface is in physical port 1 anyway, it seemed as good a place to start HEPAX RAM as any. Port 2 is reserved for expansion of HEPAX RAM, and I'll place other tools in the three remaining pages.

I hope I only need to substitute YFNZ for YFNP and PWRX for PWRL to get the extreme versions of the two modules working. I'll wait a few days before trying THAT so I can get more familiar with PowerCL. I wonder how others switch between favored configurations. Do you do it manually, programmatically, MMU register copy to sRAM or via the secondary MMU registers?

Much remains to explore!
