(SOLVED) 41CL - DOUBLE HEPAX ACCESS and MMU CONFIG

[Podalirius]

Hi, this is to reply to you Mr, Sylvain Cote and to Mr. Monte:

-To Mr. Sylvain Cote:
I don't know English so well to write a letter without the help of a dictionary,
so I need same time to write a message and post it here.
When I wrote my previous message your last messages (of you and of Mr. Monte)
are not present. Only then I confirmed my message I see and read your last messages!
I understood that installing the Hepax module on two MMU is a complex thing,
if is possible, because I don't know how to make the Hepax RAM pages accessible
also by another equal installation on another MMU.
I read very carefully your explications, because these are more similar to a book
on 41CL rather than 41CL manuals.
If installing Hepax on two MMU will be not possible, I will be happy again, because
of this things that you explain and teach me!

-To Mr. Monte
It is possible I am wrong: I thought that after XEQ CFGINI, with EXCFG I can swap
the MMU configurations without any problem.
Mr. Sylvain Cote teach me that this is not so easy.
I have a pyILBOX to connect the 41CL via HP-IL to some emulated periferals so I
use frequently the HP-IL. My first configs after CFGINI are readable In my second reply.
When I given the command EXCFG F the 41CL crashed, I extracted and reinserted
the batteries and obtained MEMORY LOST. Reading your instructions in 41CL Extreme Functions
and in 41CL Memory Functions, I see that the YFNX in port D on 9HIL was now present
also in the 9PWR installed by me in MMU 0 with RCLCFG 4.
Tha 41CL display DUP XROM 15, then, CONFIG BAD.
After many others attempts, with or without MEMORY LOST,
I thought to make this operations:
Procedure A - EXCHANGE MMU so that MMU 0 = 9PWR and MMU F = 9HIL
XEQ EXCFG F
XEQ MMUDIS
"EMPT 6" XEQ PPLUG to destroy PRINTER
"EMPT 7" XEQ PPLUG to destroy HP-IL
"PWRX" XEQ PLUG1L to overlap the OSX3 from 9HIL
"OSX3 6" XEQ PPLUG
"YFNX 7" XEQ PPLUG
XEQ MMUEN

Procedure B - EXCHANGE MMU so that MMU 0 = 9HIL and MMU F = 9PWR
XEQ EXCFG F
XEQ MMUDIS
"EMPT 6" XEQ PPLUG to destroy OSX3 from 9PWR to make space for PRINTER
"EMPT 7" XEQ PPLUG to destroy YFNX from 9PWR to make space for HP-IL
XEQ MMUEN

After installing 9PWR on MMU 0 with TCLCFG 4:
XEQ EXCFG F
Procedure B
OFF and ON
OK
To return at standard config MMU 0 = 9PWR and MMU F = 9HIL:
XEQ EXCFG F
Procedure A
OFF and ON
41CL crashed, than MEMORY LOST.
I hope this is of some utility for you,
but it is possible that all this is useless for you. I am not
an assembler programmer, and is possible that my tests are very
insufficient. This is actually the best of my knowledge.

I thank so much ALL of you!

P.S.: For me the 41CL, without the help in this Forum, is very similar to an iron!!!
It is for it that I greatly appreciate your work and help!!!
