Version Info TTCALC

----------------------------------------------------
ttCalc is a simulation of the calculator HP41-CV(TM) 
            from Hewlett-Packard Inc. for Microsoft 
            Windows 3.1  

ttCalc is a PUBLIC DOMAIN PRODUCT 
            (see also LICENCE.TXT)
----------------------------------------------------		

Sorry, this is the GERMAN - version of ttCalc. 
I hope the english version of ttCalc will 
be released in late May or June 1994 together 
with the english help-file.


System requirements:

 - CPU 386SX or better
 - Microsoft Windows 3.1 or higher
 - VGA or better
 - about 0.6 MB memory on a fixed disk drive

There is no SETUP/INSTALL - program for ttCalc. You 
have to do it by your own. Follow these steps to 
install ttCalc:

1.   Create a directory on the fixed disk 
     (f.e. C:\TTCALC). 

2.   Copy all files to this directory.

3.   Add the font library 'TTCALC.FON' whitin the 
     new dircetory to the existing fonts of Windows
     (important !).  


4.   Optional: If you have no soundcard, for example 
     Sounblaster(TM), installed, you have to install 
     a driver for the loudspeaker of the PC, in order 
     to use the sound capabilities of this program.
	
5.   Create a new group for the program-manager and/or 
     add the program TTCALC.EXE to an existing group 
     of the program-manager.



Version 1.0:	03/01/94	
------------------------
1. First Release 


Version 1.1:	12/30/96
------------------------

Fixed several bugs / others not (Thanks to Ingo Kelmes):

1. Version number included 
2. Aview should now work
3. HMS, HMS-, HMS+ and HR bugfixed
4. <SHIFT><FIX> <~+> --> fixed
5. There are some spurios memory losts but less more
6. This problem of internal accuray does exist longer:
   f.e:
	60
	COS
	.5
	-
	not equal to zero
7. <SST>, <BST>, <GTO> <.> ___, <DEL> ___ leads to a memory lost -> see below
8. No entry to synthetical programming
9. AON - Bug fixed
10. X<> L - Bug fixed
11. '=' Character is still very small on top of the '2'-Button
12. Leaving or entering the program mode forces a 'pack', because
    i do not know how the hp41 behaves
13. Cat 2 included (see below)
14. Standard Configuration fixed after memory lost 
    -> SIZE 273 , REG 011, CLRG added
15. SIGN - Bug fixed
16. ASN - Bug for last line fixed
17. Spurious font bug fixed, i hope so i had never such a problem



New features for Version 1.1:
_____________________________


1.  English and german menu, layout and dialogs 
    But still no english help file
2.  Rom compatibilty included
    With IO-Functions
    To load rom-moduls add startup modify
    'ttcalc.ini' to your specific rompath
    and copy any rom modul wanted to this path
3.  Makerom.exe included to build rom-files  (source included).
    With a lot of programms in ASCII - Mode and as rom mapped - file.
       for 'MATH_1B' 	-> Math Modul
	   'STANDARD'	-> Standard Book from HP
	   'WICKES'	-> Wicke's bible
	   'J.S.DEARING'-> Dearing's Tips and tricks
  
4.  Extended clipboard functions:
	Try to use :
	^C within PRGM-Mode copies the current programm to the clipboard
	   (valid for ROM and RAM Mode)
	^C within CAT-Mode copies the current catalog to the clipboard
	^V Copies 
5.  COPY-Function included
6.  Extended file-io functions:
	It is now possible to load/save/close a programm (PRG), 
	Key-Assignments (KEY),
        rom - moduls (ROM) and still the simple memory image (MEM)
7.  Sorry, but installation procedure not yet done
8.  Sorry, its a little bit beta version (menu aren't correct disabled
    because my new compiler VC 1.52 doesnt behave like MSC 7.0) but i
    hope some friend can help me to this and may be other problems.
    Ps I have only a lot of time till 1/6/97



Version 1.1b (internal Version):	1/03/97
--------------------------------

1.  Added IO-Routines to save Assignments (ASN)
2.  Added IO-Routines to save Registers (REG)
3.  Assignments (<ASN>-Function) now can be verified within the 
    ttcalc - Window.
    The Function assigned will be displayed on top of the button
    for nonshifted keys and above the butten for shifted keys.
    Disadvantage: It's done in idle mode, so the calculator 
    spents a lot of time and is really doing nothing
4.  Some Font work for a better button display 

Version 1.1c (internal Version):	1/04/97
--------------------------------

1.  Makerom modified to compile more than 32 files 
    (now up to 128 files) -> Makerom New Version 1.0b
2.  Fixed nnz-bug 
    NNZ often becomes 0 by normalization 
    As a consequence most synth. programs did not work in version 1.1b and 1.1
3.  Added many new PRG's from Dearing's book
4.  Fixed some rounding problem
    <DEG> <60> <COS> <0.5> <-> gives now 0.000
    Matrix - Programm from math-modul gives now same results as in hp-book !
    Solve - Programm from math-modul gives now same results as in hp-book !
    Disadvantage : Execution time increases
5.  Jumps (<GTO><xy>) has not been reset in version 1.1 and 1.1b 
    So now jumps will be reset if prgm - mode is leaved !


Version 1.2:				1/04/97
------------

    identical to version 1.1c, but copied to winsite

Version 1.3:				1/05/97
------------
1.  Enabling / disabling  menus now works
2.  Second try to bugfix HR/HMS ...
    The problem arises from binary arithmetic
    Internally every hp-number is converted to dbl and then back to a
    10 digit number ...
    I hope it works now ...
    The <HR> <HMS> <HMS+> <HMS-> Functions described witin the manual works
