Hi, gang,
I've got a single EPROM file that I need to split into separate odd-byte/even-byte
files for programming into two separate (smaller) EPROMs. I'm not able to figure out
how to make the Unisite programmer do this, so I'm thinking a DOS or Windoze based
splitting utility will do the trick.
Here's the problem; I've searched all over Google, and can't find anything
that'll work.
Any ideas?
Thanks much.

Is the file "readable" -ie text that may look like:
0000 00 11 22 33 44 55 66 77
0008 88 99 aa bb cc dd ee ff
000f 10 11 22 33 44 55 66 77
(only lined up because this is not a monospaced font)
You could write somthing quick and dirty in perl/basic/python/c/other
language of choice
All the above probably available to a windows/dos machine.

Jerome Fine replies:
If you are desperate enough, I can easily write something to run
under RT-11. In MACRO-11, that would be dead easy. In
C, it should be just as easy and with FORTRAN - just open
the file and copy the bytes into two output files.
But then, unless you have not written any programs lately,
I would think it would be just as easy under any operating system.
However, I have chosen to stay away from writing software
except under RT-11. There is too much I want to do there
and never seem to get the time - well, no one else seems to
be interested in any case. So I don't have any compilers
available except under RT-11.
Sincerely yours,
Jerome Fine

SRecord by Peter Miller does that and a lot more. Originally written for
Unix, but there are prebuilt binaries for Windows NT. I'd be somewhat
surprised if they don't also run on Windows 95/98/ME/2000/XP.

This may sound harsh, but what is your favorite programming language?
It would be an excellent exercise for learning some programming.

Agreed. I've had to write many 1-off utilites for scrambling data to get
it into EPROMs over the years (when the address/data lines to the EPROM
on the target board aren't in the normal sequence, or when I need to
split/combine bytes to/from words, etc). It shouldn't take more than an
evening to do the entire job, and I don't claim to be a programmer.

Dito. :)
On a real machine a good assembler is nice. I don't consider the PC
a real machine. I think CPU development went down hill after they forgot
about Machine Langauge programing.

Yes, it is harsh, and such a statement is of absolutely no use to me since there are
plenty of other things I have chosen to devote my time and energy to.
I am, first and foremost, a hardware hack. I have a ton of respect for all the folks who
have chosen to be code jockeys, but pesonally, I'm far happier with a soldering iron
in one hand and a schematic in the other. Typing and debugging code all day, beyond the
few scripts and config files I use to keep my 'net presence alive and well, would
drive me nuts in less than a week.
In short; I will do it if I have no other way to accomplish my goal. However, I will
always search for a pre-written alternative (yes, I buy stuff from shareware authors)
before I think about rolling my own.
Fortunately, a number of other list users have offered outstandingly helpful pointers
(thanks, troops!) As it turns out, it's not an odd-even split I need; It's
high-byte/low-byte split. I'm still digging, and I find I often learn more along the
way than I would if I sat down and started coding.

Whic programmer do you have? Most that I'm familiar with (Needham, DataIO,
BP Microsystems, Tribal) all have a utility that after downloading the
image, allows you to program either the high byte or low byte of the image.
Is your programmer one that's perhaps a standalone unit that doesn't support
this?

IMO you're a lot better off using existing software/hardware/whatever and
spending your time on more productive pursuits. I CAN write code in BASIC,
I figured that out, yes. In fact, I've found a number of utilities that come very
close to what I want to do. The situation, though, was rendered academic when the
manufacturer of the device I was trying to do the EPROM for chose to send me a pre-made
update.
In retrospect, that's probably better. It seems that the latest code for the SCSI bus
analyzer I got is, by itself, larger than would normally fit into a 27C010 device.
However, it seems that the engineers behind it pulled some goofy tricks (utilizing gaps in
the original code image) to make everything fit. The downside of that is, of course, that
the only reliable source of updates is an exact binary image of the updated EPROM,
something that they did not have on their FTP site.
Assembly, several machine languages, Fortran, Pascal,

Right. I don't particularly enjoy it. Never have, never will. I'll do it when
needed, and I certainly take pride in my work, but there are limits. ;-)
Keep the peace(es).

OK
Sorry, some of us forget that not everybody enjoys programming.
If you have a K&R compatible C compiler, here's a quick, crude one for
you. For some compilers/OS's the "rb" and "wb" need tobe
"r" and "w".
IF each of the output files is half the size of the input file, then it
worked.
If you want input of the filenames, better error checking, verification of
file content, etc., that can be added later.
#include <STDIO.H>
#include <FILE.H>
main()
{
int x;
FILE * FPIN, FPO1, FPO2;
FPIN = fopen("INPUT.DAT","rb");
FPO1 = fopen("OUT1.DAT","wb");
FPO2 = fopen("OUT2.DAT","wb");
while ((x = fgetc(FPIN)) != EOF)
{
fprintf(FPO1,"%c",x);
x = fgetc(FPIN);
fprintf(FPO2,"%c",x);
}
fclose(FPIN);
fclose(FPO1);
fclose(FPO2);
}

However, I have realised over the years that sometimes I have to write a

For me, it depends on how long it would take. I probably wouldn't
consider writing an OS or a language compiler from scratch. But for
something like this it would probably take me less time to write it than
it would to search for something that might do what I want.
An analogy. You have a well-stocked junk box containing many DB25
connectors, and drums of multi-core cable. Your soldering iron is, as
ever hot. You need a null-modem RS232 cable. The nearest shop that sells
them takes you an hour (each way) to get to.
Do you spend a couple of hours going out to buy one, or do you solder one
up from the contents of the junk box. I know which I'd do. And I don't
particularly enjoy making cables...
Same with programming. If it's going to take about half an hour to write
the program, well, I grab K&R, and start coding...

It was thus said that the Great Tony Duell once stated:
Might be a big-endian/little-endian issue. A Z80 (if I recall) would lay
down 16 bit quantities as:
L0 H0 L1 H1 L2 H2 ...
while a 6809 (which I know) would lay out 16 bit quantities as:
H0 L0 H1 L1 H2 L2 ...
So maybe that's what he's talking about?
