We've been using one (IF you mean a M68000 simulator running under
MS-DOS, and not a simulator of a second-rank teacher) for some years,
very successfully.  It was written by Steve McCusker, who was on faculty
here.

Steve's simulator gives you a full-screen text display of a slab of memory plus
registers, with a menu of old Turbo Pascal style one-letter commands. 
Breakpoints can be set for write, instruction fetch, or any access in a
range of addresses.  There are I/O ports, with interrupts, for a
simulated keyboard and printer.   We use it with a Raven OCHO cross-assembler
and the current Turbo Pascal editor to introduce assembler programming at
freshman and sophomore levels.

If you'll please confirm (email suggested) that you are looking for something
like that, we can meanwhile find out Steve's address - he's in England 
at present.

Since the FINTRZ instruction is not directly supported in the 68040,
is there another instruction one can use in its place, how does
one optimally get the integer portion of an <ea> or FP register,
on the 68040?

It is not necessary for your hardware to maintain high-Z on the other half
of the bus. You can assert a 16b word, and the 68000 will just "take" what
it needs. It's done all the time.

  Thanks for the info guys.  Yes that was a typo...it is a 332 XT 
Card.  For the most part the system is more than fast enough for what 
I plan to use it for (running a Public Access Unix Site).  But if 
anyone does have one of those 147 cards for sale at a reasonable price 
or trade for something (prefered), drop a line.
 
  As for the 1 gig seagate, that would be way out of my price market 
at the moment, but Its nice to have a list of whats available for the 
future. 
 
  Its nice to see that the system is upgradeable (of course it is, its 
just a VME chassis....), but if anyone out there has a more recent 
version of the OS, one that I can comile some more up to date 
applictions on (like BSD EMPIRE, and possible using it for an X server 
to my PC's), let me know and I'll mail a tape (willing to trade for 
something if needed).
 
  I'm pretty sure the harddrive is an ESDI, it dosen't appear to be 
incredibly fast, but at least it's reasonably big.
 
  I plan to get a full uunet feed soon, what software will I require 
(ELM, qwk programs, etc)?
 
                                    
One more thing, if anyone is interested, we have a bunch of the 68010 
version of these machines (I think its a bit smaller chassis as 
well), coming back from the field soon.  We used them as FEP (Front 
End processors) for our Central Monitoring Stations (Alarms).  We just 
recently upgraded to RISC 6000 systems to the Motorola sys's are soon 
to be junked (Though I plan to try to get my hands on a few if 
possible).  They were running VERSADOS, not unix, anyone know if UNIX 
was available for them?  (If you require full part numbers, let me 
know and I'll do some digging for them).  Or is my SYSV tape useable 
on them as well? 
 
 
                                    Thanks

At first I also was quite confused by this.  After studying the CPU32
Reference Manual, I think I've got it figured out.

There are two forms of the divs instruction: word and long.  The high
nybble of opcodes for the two forms is different - these are actually
two different instructions.

So, considering only the long form I see two fields in the Instruction
Format which govern the instruction's behavior: SIZE and REGISTER Dr.
The description of the Register Dr field states, "If Dr and Dq are the
same register, only the quotient is returned."  Here's the truth table
I derive from the verbiage:

      assembler syntax   | SIZE | Dr == Dq |    operation
    ---------------------+------+----------+-----------------
     DIVSL.L <ea>,Dr:Dq  |   0  |    NO    | 32/32->32q:32r
     DIVS.L  <ea>,Dq     |   0  |    YES   | 32/32->32q
     DIVS.L  <ea>,Dr:Dq  |   1  |    NO    | 64/32->32r:32q
     ??????              |   1  |    YES   | 64/32->32q

Has anyone ever tried to execute the opcode resulting from the last line
in the table?  (Who EVER said that the M68000 family has an orthogonal
instruction set???  Flame if you want to.)

successfully loaded Windows 3.1. SInce I saw a PS/2 style keyboard connector
on the back I scrounged a PS/2 keyboard and it works great. 

One problem... The mouse. There is a PS/2 style mouse port on the back of the
system. I tried a IBM mouse which fit but doesn't seem to work. I tried all
the mouse options in the Windows setup utility and none seemed to wake up the
mouse. When the system was hooked to the 6085, the mouse was plugged into the
keyboard. I was wondering if there were a hardware jumper on the motherboard
or something that I had to set.  Any ideas are welcome.

Tue Oct 06 12:03:18 1992

Well, first of all hello to y'all out in the Net, from RIG 59 BBS (WWIV)
here in beautiful Southern Illinois!

I'm working on a program in Turbo C, and want to do a checksum on a hard
disk's boot and partition record (similar to F-OSCHK in the F-PROT
anti-virus package).  As a result, I'd like to know the exact sectors
where these records reside.  (I have a DOS programmers manual ordered,
but I'm getting impatient. <grin> )

While I'm at it, what's the absolute location of the hard disk serial
numbers generated by DOS 4.01 and above?

Finally... does anyone know why the C function absread (read absolute
sector) would fail on DOS 4.01 and DOS 5.0 but run perfectly on DOS 3.3?

Thanks!

Greetings:

We are developing a high-speed, multi-processor switch.  The
master processor is an 80386 and the network ports are slaved by
80186's (4 ports per 186).

Currently, as the product is still in it's early development
stage, we are surviving by running MS-DOS as the operating
system.  DOS simply does not suffice for the tasks we require
of the O/S; it's not fast enough, memory problems/limitations
etc.  Ideally, we would like to write a customized O/S for
the product but at the same time do not want to re-invent
the wheel.

The requirments for the O/S are very minimal -- bootstrap,
loader and rudimentary file system.  There is (or will be)
some sort of secondary storage (hard or floppy disk most
likely).  The only specification is that the O/S needs to
be as fast as possible. Questions I pose to the net, then, are:

1)  Is there a commercial 32 bit BIOS available for the
	386 architecture?

2)	Any sort of 32 bit 'stripped down' file system available?
	Even 'code snippets' at ftp sites would be helpful.

3)	Even better than 1) or 2) would be an actual 'bare-bones'
	32-bit OS as detailed above.

Any info/comments would be greatly appreciated!

Best regards,

Mike

That's not so long.  That's even shorter than the specification maximum

Actually an NMC is rather loosley defined but in general it means:

Computer 1         Computer 2
    Pin                Pin
     1 ---------------- 1 (Often omitted)
     2 ---------------- 3
     3 ---------------- 2
     4 ---------------- 5
     5 ---------------- 4
     6 ---------------- 20
     7 ---------------- 7
     8 ---------------- 8
    20 ---------------- 6

From this you have to decide what your system needs.  For example pins 1 and
7 are both ground and generally connect internally and pin 1 is often left
off if there is a shortage of wires.  2 and 3 is for data and are generally
required but in **very** rare cases only one may be required.  Note that
even if data is one way, for example on a printer, you may still need the
back channel for XON/XOFF handshaking.  4 and 5 are used for handshaking.
If one device requires this but the other doesn't support it you can tie
these lines together like this:

     ...
     3 --------------- 2
     4 -----     ----- 5
           |     |
     5 -----     ----- 4
     6 --------------- 20
     ...

If one side requires CD and the other supplies it at appropriate times you
should include pin 8.  If it isn't supplied you can share the input from
pin 20 with pin 6.  Here are 2 "classic" NMCs, a 5 and a 6 wire one:

Computer 1         Computer 2
    Pin                Pin
     2 ---------------- 3
     3 ---------------- 2
     4 -----     ------ 5
           |     |
     5 -----     ------ 4
     7 ---------------- 7
     6 ---------------- 20
         |
     8 ---          --- 8
                    |
    20 ---------------- 6

Computer 1         Computer 2
    Pin                Pin
     2 ---------------- 3
     3 ---------------- 2
     4 -----     ------ 5

According to my diagram for a full handshake null modem, the connections are:

1----------1
2----------3
3----------2
4----------5
5----------4
6----------8 and 20
7----------7
8 and 20-----6

This works.

You are only contractually obligated by terms you specifically acknowledge,
and by a small set of implicit terms -- the nature of which are presumed to
be apparent to even the common man.

In other words, unless it said on the box cover that you could not resell
it if you bought it, you *can* resell it.  You cannot be bound by conditions
kept secret from you, nor those thought up after the sale.

I have a WANG VS OIS System 60.

Can anyone help me?  Iam trying to move files from it to a PC.  I want also to 
figure out how to use the RS232 ports...

Thanks
