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

A good while back I hauled home what was the control box of an 8"
floppy duplicator. The information of the box:
Formaster Corporation
1983 Concourse Drive
San Jose, CA 95131
Model 4400
I hauled home only the control box thinking the case might come in
handy for some project. Earlier I opened it up and found a card
cage full of what I assumed at the time was Q-bus cards. Now with
the aid of the Field Guide maintained by Megan, I have identified
the main card as a Q-bus LSI-11/2 CPU 16-bit card.
I have no need for the cards and thought some might be of use to those
on the list. A couple of the cards were made by Formaster, so doubt
much demand for proprietary cards, but are included anyway.
Cards 1-4 are dual height and 5-7 are quad height.
So here is the list:
----------------------------------------
1) M7270 KD11-HA LSI-11/2 CPU 16-bit Q-bus
----------------------------------------
2) National Semicondutor Memory Systems card
Has 4 rows of 9 4116's, so 64k
Numbers on the card:
55110358-003C 980103858-001 REV L
----------------------------------------
3) Sigma Information Systems
This card appears to be a disk controller. It has 4 WDC TR1865PL controller
chips on it and there are 4 ten pin header connectors on the card edge.
Numbers:
Assy 400200
CPX-6-0
----------------------------------------
4) Formaster Corporation
I would say this is a proprietary card.
Only meaningful number 003-30026-01
It has a 50 pin header connector and a 16 pin header connector.
----------------------------------------
5) Acorn Systems memory card
Has 8 rows of 18 4164's, so 1 mb
Numbers:
Copyright 1981
30019-01
----------------------------------------
6) Acorn Interface and ROM card
I am guessing on this one. I say interface because has 4 50 pin
header connectors and 1 34 pin header connector. IIRC, the 34 pin
went to the front panel control board.
It also has 4 EPROMS (24 pin) with ID stickers on them (Formaster)
----------------------------------------
7) Formaster card
I would say this is a proprietary card.
Only meaningful number 003-29978-01
It has two 50 pin header connectors.
----------------------------------------
If you would like one of these cards, then here is the game plan.
1) Send an email reserving your card(s), first come first served.
2) I will not ask any specific amount for these cards. I will ask
that you send something to cover a little of my time and the trip to
the post office. I'll leave the amount up to you. Hint: Priority
Mail stamps make nice tokens.
3) All cards will be shipped by Priority Mail, one card to a box.
So send a $3.20 stamp for each card you want. Your card will be
properly packed and mailed back to you.
4) Any cards reserved and no stamp received by October 15th will
be 'unreserved' and tossed into the recycle pile.

Yes. I'm sorry I wasn't more clear. I _did_ mention the 32-bitness of
the target machine.

Right. If all I wanted was four 64KB files that concatenated into the
original, I could use split.

Also true. I'll be guessing because the ROM sockets are not numbered
on the board. :-( It's a VAXstation/MicroVAX 2000, if anyone happens
to know what the EPROM byte order is.
I got an EPROM splitter utility from Don Maslin (thanks, Don!) It
appears to be just what I was after.
Sorry for the confusion and wasted bandwidth.

This is a semi-repeat request. Please excuse the bandwidth.
I'm playing with an old machine that has AT&T SysV UNIX Release 4, Ver 2.1.
There is no TCP/IP networking package that I can find. Can someone tell me
if TCP/IP is available, and from where it may be gotten? The post about the
VAX got me interested again...

The 2010 discussion is interesting to me.
I have a SMC 2010B with a date code of 7736 in Ceramic with gold legs. Is
this a second source of the Western Digital or something different?
I also have a couple of similar chips by SMC, a Plastic/gold 2009H with a
date code of 7942D,
and a Plastic/gold 3007-A01 with a date code of 7852A. This one has a P.N. of
27-001 on it also and is a 28 pin dip.
The first two, the 2010 and 2009 are 40 pin dips.
All seem to be limited production run chips as I have not seen others of them.

Cool, typical of many non horizon NS* systems. A bit of this
and that.
Uhm what are you using for keyboard input if the VDM is output?

I did some looking and find nothing that says Lifeboat did 1.3
for NS*. The copy I have is 1.403 for NS*. They may have
done 1.3 but the timeframes for 1.3 and Lifeboat are off.
Sounds like you need more ram. Get another 16k for safety.
A cromemco ram16 or ram17 should be easy enough to find
or other 64k static.

It's an art and science.

Picked up an Intel brand Pentium 100, runs OS/2 nicely. Also found a DEC MicroVax II with 2 4-line serial controllers. No drives, but I have a few spares. Time to froray into VMS.
Last Sunday I went to see the Woz speak at the Mac Group of Detroit. Fascinating speaker, if anyone has the chance to see him I highly reccomend it. He talked in-depth about working at TI, designing Breakout with Steve Jobs for Atari, and designing his own computers at the Homebrew Computer Club. Most fascinating factoid: He was inspired to make his first TV-display terminal when he paid a visit to Captain Crunch and saw that he had a Teletype in his apartment, and was "Talking to some guys in Boston!" over Arpanet.
Hi,
I have only one diskette that came with a Heathkit H89 computer. It's
a soft-sectored 5 1/4" Dysan 107/1 flavour. I also have a couple
boxes of "newer" 5 1/4" diskettes that i used in the IBM pc world,
which are also soft-sectored, but are double sided, and single or
double density. I am wondering if i can reformat these (in CP/M for
example) and use them in the H89? It makes sense that i should be
able to do this, since they're obviously better quality (ie. can
store more info) than the older SSSD's, but I'm not sure if I can do
this. I would test it, however, at this time, i don't have format.com
for the H89.
Thanks Bob

No that would be about right for that chip... 1987. My 1985 SMC catalong
lists
the 2010 as "preliminary".
