2021-10-11 - in the future, I will use LibreOffice instead of OpenOffice, e.g.
for the spreadsheet tools below.
Files may still work with OO, but I won't test
it.
while using the 1401 SIMH simulator to compare results to the VDC to help
find bugs, I missed the 'dump' command,
which doesn't seem to be implemented in the 1401 simh (at least in the version I
used).
Unfortunately the ROPE system also doesn't work on my PC (don't know why, maybe
java issues).
Instead of implementing it myself into the simh source, I decided to use the
simh 'ex 0-15999' command, combined with a
preceding 'set console log= <file>' command to get a list of all memory
locations.
This spreadsheet helps creating a nicely formatted table with characters and
word marks from this export.
Simply copy and paste the text part with the memory export from the log result
into A1.
download the "SIMH 1401 ex dump beautifier vx.jpg" (LibreOffice) from the download folder:

This spreadsheet helps creating a stack of cards which can be read into the 1401
memory using the 1402 LOAD function.
It also offers a lightweight assembler which calculates addresses and labels.
special feature: you may use "&<label>" format to address the right/upper
address of a data field, just as required by e.g. the M command.
currently only working with openOffice; needs some work to run with Excel.
download the "H1401 program sheet v? - program template.ods" (LibreOffice) from the download folder:
download
you may enter the program on the "program sheet" and add data on the "data
sheet".
the resulting card stack can then be copied from the "cards" sheet.
on the "program sheet" and "data sheet", you may insert or delete rows in the
program/data area w/o disturbing the processing
(e.g. by marking lines with shift-space and then pressing ctrl-<plus> or
ctrl-<minus>)
pls. follow the rules and hints written in the file.
it's a very simple 'assembler' based only on spreadsheet functions, so don't
expect too much.
