Hi Dick
I use a PC to develop on. I don't have enough ROM space
on the 4004 system to do very much. The developement
system is currently running the code that came with
it. It was intended to program 1702A's. It does this
well.
I am writing code to make a 4 function calculator
that runs through the serial line used for the programmer.
I've desided to use BCD math since it has instructions
built in that deal with doing BCD corrections. The RAM
orginization is well suited for 16 digits of BCD for
each data value.
To get copies of my tool set, down load:
ftp://ftp.hal.com/pub/elvey/I4004.ZIP
You'll also need a Forth interpreter because everything
is in source and not precompiled. I used the Freeware
Forth called FPC. You can download a copy from the
site:
http://www.forth.org/compilers.html
I also included tools to convert Intel hex to binary
and back for those that need this format for their
particular programmer. There are some assembly example
files called *.AS4 that will get you started.
Let me know if you have any questions. You don't need
to know Forth to use the tools but you can do more
advanced things if you do. For the most part, the READ.ME
file should be enough to get you started.
What is your interest in working with the 4004?
