Difference between 9577-0NA and 9577 QNA
Stephen Lobo
What is the difference between a 9577-0NA and a 9577 QNA. I couldn't tell
from the FAQ. Where can I find an updated interpretation of the 3 character
code at the end of the PS/2 model number?
Thanks,

How's about this:
<paste>
There have been so many different PS/2 models, past and present, that it can
be difficult to tell them apart just by the model
numbers. The following is an attempt to explain the meaning behind these
numbers. Despite appearances, the numbers and
letters do have specific meanings (although in a few cases their use is not
totally consistent).
In an attempt to simplify the process of understanding model differences,
recently IBM started using a new system for
designating models. So, below you will find two sets of explanations, one
for the older scheme, and the other for the new
method:
Note: @ = A or B; * = Any number or letter.
Old Method: (PS/2 Models 25, 25-286, 30, 30-286, 50, 55, 60, 65, 70, P70,
P75, 80)
Models Meaning

@16 160MB Hard Disk drive
32* 320MB Hard Disk drive
40* 400MB Hard Disk drive
A** 25MHz 386 processor
A3* 25MHz 386 processor; 320MB Hard Disk drive
B** 25MHz 486 processor
C** Color Display
E** 10MHz 286 (30-286 only)
E6* 16MHz 386; 60MB Hard Disk drive (70 only)
G** Enhanced Keyboard
L0* 4MBps Token-Ring LAN adapter (25 only)
LE* Ethernet LAN adapter (55 only)
LT* 16/4 Token-Ring LAN adapter (55 only)
M** Monochrome Display
*2* 20MB Hard Disk drive
*3* 30MB Hard Disk drive (Except A3*)
*4* 45MB Hard Disk drive
*6* 60MB Hard Disk drive
*8* 80MB Hard Disk drive
**0 Medialess (no Hard Disk, no diskette drives)
**1 1 diskette drive
**1 Monochrome Display (25 only)
**2 2 diskette drives
**4 Color Display (25, 25-286 only)
**6 10MHz 286; 1 diskette drive (25-286 only)
To illustrate:
Models Meaning

So, the main thing about a -QNA vs a -0NA is that PC-DOS 5.02 and Win 3.1
were pre-loaded on the system at shipment.

That makes things a bit easier to follow. But how about a 9577 STG? The T is
ok, it's the 486DX4 processor, and the G goes with the 540 harddisk also,
but what about the "S" ? On the IBM site you can choose the 3-digit code to
specify your 9577, but no STG. There are *TG's with 6, 7, A and B
mentioned, which concurs with the explanation you supplied. There is even a
VTG that is not in your list, but again no STG. And it sure is STG what it
says on the machine. It is not a multi media model so 6 and 7 are out, but A
would have been right since it has the IDE connector on the planar, B would
have been possible also since it has the SCSI-2. Next to that there is the
L2 cache and the VRM module which may have been optional, and a 1gb second
drive and SCSI 2x IBM CDROM (tray) which are even more likely to come from
the option list rather than standard trim. I'm quite sure the PC was
supplied by IBM in that configuration though.
I wonder if somebody can explain the S code? Maybe 16MB RAM instead of 8?

I can't esplain the Sxx code, but generally you should be aware that (maybe
in order to confuse them technology-stealing communists <vbg> or whomsoever)
IBM did not use the same lettering system throughout. So, for instance, the
9595-0Kx and -0Lx are -- or rather were -- called -AKx and ALx on the German
market.... and not even Peter Wendt knows for sure why they did it...
And, no, they did NOT have IDE standard, nor 25 MHz 386 boards....
But for that obvious reason I had the same problem specifying the
three-digit code on IBM's website -- it did offer 0Kx and 0Lx, but no ALx...

(someday), but here's some additional info I've got on some (maybe
lesser-known) PS/2 77 types.

Well, the -Vxx models have the IBM Fast+Wide SCSI-2 controller instead of
the
IBM Fast SCSI-2 (OEM version of FD MCS700).

Not unless it came with IDE drives attached.

It looks like this is the nearest match. Perhaps an EMEA-only code change,
from what Tam posted elsewhere in this thread. Like 90s/95s being -Axx in
EMEA, but -0xx in the U.S.
>Next to that there is the L2 cache and the VRM module

Nope, 256KB L2 standard on -xTx. VRM *required* for 3.3V(3.45V?) DX4-100.

Dunno, can't say that I've ever seen or heard a reference to an -STG.
Perhaps multi-drive, more RAM or different preloaded software,
but essentially a -BTG, I would guess.

postings in response to my question above. Now, on behalf of all us PS/2
newbies, will someone *please* update the PS/2 FAQ with this information so
it is easily found. Is Chris Feeney still maintaining the FAQ?
