In 2016 Mike Silva gave SynCalc into public domain including source code! Mr. Silva, the Atari community is forever in your debt! Thank you so much, we really appreciate your help. You are now in the hall of fame.\\
\\
[{Image src='Thank_you_Mike_Silva.jpg' width=512 height=112 }]
Thank you Mike Silva!!!\\
\\
Further credit goes to Brian Lee, the product manager, who was very involved in guiding the look-and-feel and the overall functionality of the program. Thanky you so much Mr. Lee, we really appreciate your help, then and now. :-)\\
\\
Because the source code listing as well as the disk files are lost, it would be cool, if someone out there is in the possession of that, if you can share it with the community. Many thanks in advance. :-)\\

!!Findings from Mike Silva:
Zero page\\
\\
$95 Current Spreadsheet Row (all rows and columns are zero-based)\\
$96 Current Spreadsheet Column\\
\\
$99 Current Screen Y\\
$9A Current Screen X\\
\\
$9F Current Cell Data Pointer (points to data of current cell)\\
\\
$A7 Last Spreadsheet Row\\
$A8 Last Spreadsheet Column\\
\\
$CA Last Added Cell Data Pointer (a stack pointer to next free memory to add new cell data) More below #1\\
\\
Non-zero page\\
\\
$1901 Array of column widths\\
\\
$19DB Last direction of cursor movement (1=left, 2=right, 3=up, 4=down)\\
\\
$1A00 Screen memory\\
\\
$2BF3 Array of 3-byte cell structures. Each structure consists of a 2-byte cell data address, followed by one additional byte (more below #2). Array order is A1, B1, C1,...n1, A2, B2, C2,...n2,...Am, Bm, Cm,...nm where n is last sheet column, m is last sheet row.\\
\\
#1 Cell data is form B1, B2, B3, cell data (variable number of cell data bytes).\\
B1: D7-D6 = number format code\\
D5 = comma flag\\
D4 = dollar flag\\
D3 = percent flag\\
D2 = ??? haven't figured this one out\\
D1-D0 = sign code\\
B2: D7-D6 = justify code\\
D5-D4 = ??? haven't figured this one out\\
D3 = protect value flag\\
D2-D0 = margin value 0-7\\
B3: D7 = protect entry flag\\
D6-D0 = length of cell data that follows\\
\\
Cell data is either text or ATARI numeric. In formula cells the value of the formula is first, followed by the actual formula.\\
\\
#2 Additional cell info byte\\
D7-D6 = cell type (01 = text, 10 = numeric, 00 = empty cell?)\\
D5-D2 = precision value\\
D1-D0 = ???\\
\\
The cell data stack grows downward from $7FFF on a 48k machine. By testing other hardware it will be possible to see where the stack begins in different memory circumstances, and also perhaps to ID some other addressing bits in the cell pointer array, bits that are just zero in the base 48k version.\\
!!Problems when importing VisiCalc files ; findings from luckybuck
SynCalc holds an import program, called: 'VC->SC' in order to read in files from the VisiCalc program. All versions(!) out there, except the original ones are not able to import properly VisiCalc files! The SynCalc program tries to load a convert program from the original program disk. If this fails, you get the following pictures:
[{Image src='1.jpg' width=330 height=200 }]
SynCalc VC->SC option selected\\
\\
[{Image src='2.jpg' width=332 height=202 }]
SynCalc asking for the program master disk\\
\\
[{Image src='3_.jpg' width=333 height=201 }]
SynCalc failed to load a program from the program master disk\\
\\
Further, if you have really hard VisiCalc spreadsheets and the 1985 version even in original form fails to import, try the 1983 version, which works like a charm in these very rare cases.
!!Private Notes from JAC! in German
Syncalc werde ich mir irgendwann nochmal im Detail anschauen, aber das braucht Zeit.\\
So wie ich das ganze sehe, was SyncCalc im Original eine XEX die von Synapse auf\\
einen DOS Disk mit einem entsprechenden DOS gepackt und dann verschlüsselt wurde.\\
Die Boot-Disk packt das DOS dann sozusagen wieder aus.\\
Nur so kann sie nach dem Booten Files von den Datendisk lesen.\\
!!Emulator Hints
In emulators it could be useful to turn the SIO patch off for using the ".ATX" disk images.\\[{Image src='SIO.jpg' width=387 height=146 }]
!!File types
The program disk itself has a hidden VTOC and is heavily copy protected. A really hard one, even in todays times. SynCalc saves produces three types of files (syntaxes):\\
a) SC for worksheets\\
b) DIF for data interchange files (or values)\\
c) TXT for reporting\\
Thank you Wade Ripdubski for finding out and sharing your knowledge with us. :-)))\\

SynCalc rating from Wade Ripdubski (InverseATASCII). AtariWiki fully admits that rating. Mike Silva has done a men's jpb. Shaft's score would be a 10 out of 10.\\
Please also take a look at Wade's site: [SynCalc at InverseATASCII|http://inverseatascii.info/2016/02/23/s2e08-synapse-software-syncalc/] ; highly recommended!\\
