Subject: External 5.25" drives for PS/2-55sx
Summary: Hands-on experience with Cumulus drives
Keywords: External drives, 5.25", 360k, 1.2M
Date: 6 Apr 92 17:54:10 GMT
Organization: Rutgers Univ., New Brunswick, N.J.

Several weeks ago I asked for recommendations for external 5.25",
1.2MB diskette drives for IBM PS/2 Model 55sx computers.  I received a
number of responses suggesting:

	Colorado Memory Systems (CMS)
	Cumulus
	IBM
	Sysgen

My requirements were 1.2MB with 360kB read/write/format compatibility,
accessed as drive B:, and 100% compatible with DOS5, Windows 3.x,
WordPerfect 5.1 and Lotus 1-2-3 v2.x and 3.x at a reasonable cost.
IBM's drives failed in two aspects: price and access as B:.  Past
experience with CMS tech support caused me to cross them off the list.
Of the remaining, Cumulus was less expensive and had the largest
overall number of recommendations.

After confirming the specs, compatibility and price with our local
reseller and Cumulus, I ordered four of the Cumulus drives with the
appropriate cables for PS/2-55's.  The drives arrived shortly
thereafter and I attempted installation.

I had significant trouble installing the drives.  The hardware and
cabling went in without much trouble, but Cumulus's installation
diskette consistantly locked-up halfway through, even though I was
booting the machines off a bare-bones DOS diskette.

I went back and carefully read the manual, and discovered that the
Cumulus drives canNOT be accessed as drive B: in PS/2 Model 55sx
systems.  I contacted Cumulus's tech support and, after 35 minutes on
hold, spoke to a technician who confirmed that the drive could not be
used as drive B: in a 55sx.  He claimed that BIOS support for drive B:
was not built into the 55sx.  I find that difficult to believe.

Since the Cumulus drive could not be configured as required, I did not
see any point to arguing the reason with Cumulus nor with resolving
the installation software problem.  Instead, I ordered 4 Sysgen drives
and adapters for the PS/2-55sx, which Sysgen guarantees can be
accessed as drive B:.  I ordered these yesterday, and will report
further when they arrive.

In conclusion, the Cumulus drives may be satisfactory in other PS/2
systems, but will not work as drive B: on PS/2-55sx units.  It is
unfortunate that neither the reseller nor Cumulus pointed this out
before the purchase, in spite of my specific questions in that regard.
If you are looking for external 5.25" drives for the PS/2-55sx, I
suggest you look into Sysgen drives.

Subject: second thoughts on an upgrade for the 50z
Organization: Stanford Exploration Project
Date: Tue, 7 Apr 1992 03:02:29 GMT

I have received several very useful replies to my first enquiry, and I'd
like to review where I am now, and raise a couple more questions.

I have decided to go with the Kingston 20MHz 386. At $350 this looks like
a straightforward and inexpensive way substantially to improve performance 
and also allow me to use Windows more productively. The 25MHz would be 
another $100, and would have imposed further cost penalties if I wanted to
add a 387. I received two postings commenting on the quality of manufacture
of the Kingston. I'll be buying it from the Source, who advertised it in
BYTE.

I'm also going to begin by swapping out my 1MB memory module for the 2MB
unit. Again, this is a significant memory increase for a rather small ($100)
investment, and does not involve a new card. Now for the two questions.

I had thought that swapping out my 30MB drive for a 60MB one would involve
nothing more than a plug-out/plug-in operation, but someone has stated that
I would nedd a new controller. Is this so? The 50z came in two flavors,
-301 and -601, and I'd be surprised (but not shocked) if they had
different motherboards. What's the scoop, and what's the solution?  I have 
a modem in one slot, and I can see another one going for memory eventually,
do I need to fill the third one with a controller or even a drive on a
card? One thing I really like about my 30MB drive is the access rates that
NORTON measures. Its FAST.

My second query concerns 387's. intel seems to have some tough competition
nowadays. What's the real scoop here? I weould only be interested in one
that fixed to the Kingston 20MHz board, and was compatible in every other
respect. Suggestions? Prices?

Cheers

Not true, actually.  The Micro Channel is generally a synchronous bus, with
cycle extension based on wait-state insertion.  With regard to bus speed, I
quote from "Personal System/2 hardware Interface Technical Reference - 
Architectures":

	The streaming data procedure provides performance improvements over
	basic transfer procedures for block transfers, and supports data-
	transfer rates of up to 80MB per second.  It provides for the transfer
	of a data block by using a single address followed by multiple 16-, 
	32-, or 64-bit data transfers within a single streaming data cycle.
	The data transfers are clock-synchronous and incorporate automatic
	speed matching between the controlling master and slave.

This rate, of course, is for adapters supporting streaming data and 64-bit
transfers.  Slaves not supporting streaming data can transfer up to 32 bits
in a 200 ns cycle, resulting in a transfer rate of 20 MB/s.

Does anyone know anything about the video setup on the model 70-121?
All I know is it is VGA, and has 256K.  It is built into the motherboard,
right?  Is the video memory upgradeable, to 512K or 1MB?
Right now I am running an 8515 monitor off of it, and am interested in
higher resolution.  Can the 8515 handle SVGA graphics?  I know it has
1024x768 resolution, but I know very little about video.  
Thanks,

I don't know about an xga/vga dual monitor combo, but an 8514A/vga combo was
used within IBM for 3277GA emulation (alphanumeric display on the vga
monitor and vector graphics emulation through the 8514A).  You will need
software support for the dual monitor set-up though.

Yes, I think it takes only 6 MB on motherboard (3 2MB SIMMs (p/n
6450604 ?). You could buy a memory expansion board, PC Magazine
had a review of MCA memory boards a while ago (about Jan-Feb 92),
Tecmar boards were the Editor's Choice.

Hi all
	
	In light of the recent postings regarding vga on the model 30, I 
have a similar question regarding the model 30-286.  There is VGA via the 
system board provided here, but it is only 8-bit video, and hence rather
slow.   Would I notice an improvement in video speed if I went with a 
16-bit VGA card?  Can I do this with this machine and stay out of trouble?
If so, I am willing to sacrifice on of my 3 slots for a little more speed.
Thanx!

The highest resolution the 8515 can handle is 1024x768.
The 55SX has a standard VGA adapter on the board which will give you 640x480.
It supports 8514/A and XGA adapters (as well as compatible ones from 3rd party
suppliers) which, with 1 MB of memory, will give you 1024x768x256 colors.

Here is the text from the IBM PS/2 Assistant software for OS/2 on what
the current reference disk versions are.  This version of the PS/2
Assistant was dated 3-25-92, I believe.

Bill Flusek, DOS Systems Specialist, Indiana University

============================  The Info  ==========================

 When servicing a Micro Channel PS/2 it is important to always use the 
 latest Reference Diskette; not only because newer versions may fix bugs 
 found in earlier versions, but more importantly because support for new 
 features (such as SCSI and XGA, for example) may not be included in an 
 older Reference Diskette.  Should you need to setup or perform diagnostics
 on a system, but your Reference Diskette is down-level, you may not be 
 able to do so.  By always knowing which is the latest diskette level for
 each PS/2 system, you can be sure that you have the latest diskettes on-hand. 

 IBM Business Partners are automatically shipped the latest diskettes as 
 they become available, but they can also be downloaded by Business Partners 
 from the IBM Technical Advisor BBS, or ordered through your IBM Service 
 Support Program Manager (SSPM).  Customers may request Reference Diskettes
 from their dealer or IBM representative. 

  PS/2 Model                   Current Version 
  Model 50/60                  1.08 
  Model 55/65                  1.05

No problem. Upgraded the 60 MB Disk with a 120 MB disk of an 70-121.

I have a Logitech Trackman connected (via a 9 pin connector) to my serial 
port on my IBM PS/2 50Z.  I would like to free my serial port up and have
the Trackman connected to my PS/2 mouse port, which is just sitting there,
making no use of itself.  Does anyone know where I can get such a cable,
which connects a 9 pin to the mouse port?  Any help would be greatly 
appreciated?  Thanks in advance.
