I'm looking to sell my 72 meg hard drive from my PS/2 model 80-071. This is
an original IBM manufactured ESDI 5.25" Full height drive, and is in excellent
working condition. Looking for best offer near or over 150.00.

Also have 1 spare 2 meg IBM memory SIMM (believe it's 80ms). Best offer over
25 dollars takes that as well.

Prefer a local SF Bay area buyer, but will consider shipping UPS COD for the
right offer.

The processor is fine for running OS/2 but it does not have enough ram and 
the hard disk is too small. You want to upgrade the hard disk to at least
80MB and you want at least 8MB of ram.

Hello.

I have a couple of questions regarding the IBM PS/2 Model 77.

I am under the assumption this computer has a standard Overdrive socket.
Is this true?  Can the end-user perform the upgrade?

Regardless, I want to know if the Overdrive socket has an "extra" row of
sockets to accomodate future processors.

I am also under the assumption that the local-bus SCSI is fully compatible
with SCSI-2 devices.
Is this true?  Is it compatible with FAST SCSI-2 devices?

One last rumour.  I've been told the SCSI is cached.  Is this true?
How big is the cache?  Can it be upgraded?

Thanks.

I have a PS/2 70 which I purchased second hand.

A few questions I'd like to ask...

1. It only appears to be running at 16MHz. I thought the 70s were at least
   DX-25s. Is there something wrong with mine?

2. If I hold down a key (any key!) and move the mouse it goes mental and
   the mouse moves and clicks by itself. This continues until I quit whatever
   program I'm in.

3. The VGA seems to be incredibly SLLOOWWWWWW! A friend of mine has a 286 and
   most games run FASTER on it! Wing Commander 2, especially, when I have it
   running with the expanded memory features. Any way I can speed it up?
   (Replacing the video RAM with faster memory chips, perhaps?)

If anyone out there can help me I'd be enternally grateful...

Ta muchly!

The battery is soldered to the d-board.  The only solutions we had to this 
problem, before all our model 30's went bye bye, was to 1)buy a new daughter 
board from IBM or 2)find an electronics supply house that would unsolder the 
old battery (actually the little clips it's soldered to) and replace the 
clips & battery with a new one.  We even experimented with having just the 
clips soldered back on and using a nylon tie to attach the battery to the d-
board through the pre-drilled holes in the d-board.  But, all our 30's have 
gone away so I don't know how well that would have worked.

There is a red colored "peg"  right above the "B" key.  The buttons are below   
the space bar key.  It may not sound very handy, but I thought it was.  The     
peg is used to move the pointer around on the screen, and was sensitive to

Subject: Bought SIMM's from Marco? read on...
Organization: CARD
Date: Fri, 20 Nov 1992 23:26:31 GMT

We have finally resolved a problem today with 4MB SIMM's 70ns for IBM           
PS/2 90/95/56/57 purchased from a company called Marco.  We had bought          
several of these units about a year ago and installed them into 90/95's.        
They were purchased as 70ns units, and the memeory chips on the units           
ended in a 70.  After receiving a pre-installed 90 with the new SYSINFO         
program (This is one _NEAT_ program - thanks IBM very much), we tried this      
utility on some of these other 90's with the Marco memory chips.  It reported   
that the SIMM's were only running at 80ns.  So I called Marco and they          
shipped us another batch of 70ns 4MB SIMM's.  These were also set to 80ns.      
With the help of the Marco technician, he had us remove one of the SIMM         
jumpers, but then the system could not recognize the SIMM.  After observing     
another set of SIMM's that were set to 70ns, I de-soldered the resistor jumper  
second from the bottom.  Now the SIMM's configure in properly and SYSINFO       
reports them to be set to 70ns.                                                 
The moral is if you purchased Marco 70ns SIMM's for PS/2, you may want to run   
the SYSINFO program or pull the case off and check the SIMM jumpers, to make    
sure you are set up for 70ns and maximum performance.                           
I am not in any way trying to discourage people from purchasing memory from     
this company, I am only concerned that users have the memory set to the         
proper speed for maximum performance.

  A cost efficient way to get much faster, higher rez, 256 color video--
 
  Check out the ATI 8524/a Ultra card. It's being heavily discounted in some
mail order companies. It is mca _and_ isa, so it has some extra resale value
built into it. It works great on my model 70 with windows and graphic apps.
I saw the card selling for around $239. I paid $369 3 months ago! And that
was the lowest price available at the time.

Subject: SCSI Ports

     I am considering getting a new PS/2 machine to replace my Model 70-A21.
 (which incidently replaced my Model 50).  Anyways, I've been thinking about
getting one of the new Model 77 machines, which among other things appears
to have a SCSI port.   Now my question resolves around the question of how
'compatible' these ports are.   I have a MC SCSI Enabler (from Procom) in my
model 70 and was very displeased when Procom informed me that the only CD ROM
decks that they would guarantee use  the board, was those made by Toshiba.  I
would like a little more choice in hardware vendors.  I have from talking to
to the Procom people, been led to beleive that SCSI on the harddisk front is
a matter of pretty much 'seamless' compatible, however they seem to be a lot
of problems with CD-ROM decks.   So if I got a Model 77, what choices would I
have (other than the IBM deck) for getting a CD ROM deck to go in the SCSI
port?

(heck I'll probably get the 77 anyways, but would still like to know.)
thanks,

Digging through some *old* documentation, a colleague actually found
our copy of the 3B2 Maintenance Reference Manual!  Rah!

Naturally, I wonder if our copy is the most up-to-date.  Here's what
our copy includes:

3B2 Maintenance Reference Manual

I also have an Addendum, dated 30 Nov 87, that added Chapter 12 and made
some minor factual corrections in other areas.

Are there any other updates/addenda/changes of which I should be aware?
If so, how might I obtain them?

In another area, are the Engineering Drawings still available for the

	ED-4C580-350		Package for XM
If these are still available from AT&T, what's the price/ordering info?  
(The part numbers for these have probably changed in the merger.)

The length depends on the baud rate.  Check with the EIA232 spec, or if
you cant find that, the RS-232C from IEEE.  I think that if you use
shielded wire, you can go 75 feet at 9600, but that is a bid "I THINK".

Check with a frim called _Altex Electronics_ in Texas.  800-531-5369.
They usualy have some inexpensive stuff, and some of there stuff is 
good, other stuff is ok, but all in all quality is better than that of 
Radio Shaft.

The 3B2/310 and /400 motherboards are identical.  You should be able to
do the case upgrade just fine, although I'm not sure where you'd
find spare cases these days.  Btw, you'll need to put in the /400
I/O cage (12 slots vs 4 for the /310), unless you don't mind a gaping
hole in the side of the machine.

Sure, I'll sell you one for $999, and I'll even through in this
great little bridge :-)
Seriously, a /1000-70 is going for about $15K at last check.
I think that price is for an "unused" system.

While reading through _The Whole Internet User`s Guide & Catalog_
by Ed Krol, it mentions a "u3b" newsgroup with "Discussions related
to the AT&T 3B computer series." (page 131)  Does anyone know any
sites that carry this?  I could find _nothing_ locally, and am
about to grab the "active" file from ftp.uu.net just to see if they
have it.

The way it is described, there is no way it could be mistaken for 
the 3B1 groups.  It basically lists "alt" then "bionet" then "bit"
... then "k12" and finally "u3b".

Curious, eh?
