OK... so without taking the time to write a C program to do this for me,
I have this binary file that is a memory dump of 256KB saved on a 32-bit
machine.. I need to output four files, 64KB each, that are the component
bytes of that memory space. I know I can write a program to do this. Are
there any handy tools lying around so that I don't have to?
Thanks,

Ethan,
I've done this in Wordstar in the non-document mode. MANY years ago I
had to transfer a 10 Mb file to a customer's computer in Canada using only
360K disks. I loaded the file into Wordstar (it will work on files larger
than it's memory) and cut it into ~330K blocks and saved each one to a
disk. When I got to Canada I simply copied and concatenated the files (copy
file1+file2+file bigfile). It worked perfectly.

Rumor has it that Joe may have mentioned these words:

Hmmm... this isn't exactly what he's looking for... he also needs to split
up the data in 8bit chunks as well, as he stated he was working with a
32-bit word file.
It sounds (at least to me) that he's writing 4 64Kbyte eproms that have to
exist in parallel on a 32-bit data bus for the total of 256Kbyte... so the
file would be like this:
byte1 byte2 byte3 byte4 byte5 byte6 byte7 byte8 byte9 byte10 byte11
byte12.............. etc.
And the four files would start out like this:
File 1:
byte1 byte5 byte9 ...
File 2:
byte2 byte6 byte10 ...
File 3:
byte3 byte7 byte11 ...
File 4:
byte4 byte8 byte12 ...
Correct me if I'm wrong, but that's how I interpret what he needs to do...

and of course, you need to know the "endianness" of the machine
where the dump was generated to see which file corresponds
to which column-slice of the rom.

I thought that too at first but I re-read his messsage and it didn't say
that. It said that he wanted to take a 256K memory dump and break it into
64K chucks for archiving so I gathered that he wanted to leave it in 32 bit
words. I'm not sure what he's really after, his message wqasn't very clear.

Yes, that the best way to do it if he's going to put it into EPROMs. I
think the site that Eric suggested
(http://www.canb.auug.org.au/~millerp/srecord.html) has a program to do
that. So that should take care of his needs.

Is anybody mantaining a combined inventory of the various computer museums out
there?
Machines I am looking for:
Scelbi H8
Microkit 8/16
Imlac PDS-1
HP 85

For the less-common machines it might be interesting to keep a kind
of database or registry. It's something that other hobbies do. It'd
be quite a task though!

Imlacs! Did you go to RPI? We went from four to about
thirty of them at the 'Wozny' Lab there. I think they
were series -X and -4's. The older ones had neat
tabletop boot consoles, the newers may have been in a
less standalone configuration. We ran a package called
"Dynagraphics" on Pr1me 750's.
I could give up my spare to someone totally dedicated
to the thing, for example if they came up with a
time effective way of repairing those rollers.

Cool, Imlac discussion! I've got one by way of Doug Salot. Mine's in
poor condition but I'm hoping one day to get it restored. I'm still
looking for documentation. Have you got any?
