General
information
5560-W, the first desktop model with 486 class CPU, was introduced
to the market on Oct. 1990 together with 5580-Y.
5560 uses same base/outer case with PS/2 Mod. 90, ( 8590
or 9590 ) but the planar and the processor
complexes are different from 8590 and 9590. Main differences are as
follows.
-
.
-
Two MCA BUS slots are prepared in stead of memory
riser connector.
-
SIMM sockets are directly mounted on the planar
-
XGA video is not ready on the planar.
-
Power connectors are not Edge Card type.
5560 Planar
All types of 5560 use same planar.

at J12.

) is placed at J7. |
Power connector
Edge card power connector is not used for this planar. J13/J23 are pin type
connectors to which female connectors from PSU are plugged. |
Model-Types
As described in At
a glance page, there are 4 types of 5560. |
5561-W0x ; 486DX25 |
You'll have enough time for cigarettes and a cup of coffee or two
until
the machine finish memory count if you have filled all SIMM socket
with
8MB SIMM. |
5561-W1x ; 486SX25 |
Memory count is faster than -W0x |
5561-W2x ; 486DX2-50 |
Most likely the complex is same with -W1x. |
5561-Nxx ; 486DX2-66 |
Supper charged 5560 with a Type-B DX2-66 upgrade platform. |

Refference
& Diagnostic
Ver. 1.11 is
commonly used for all models except 5560-N
For 556-N, use machine specific
Ref/Diag Ver.
1.0
SIMM
8 x 72pin SIMM sockets are directly mounted on the planar.
True parity 8MB/70ns SIMMs are mandatory for -W1, -W2 and -N
complex.
For W0 complex, 80ns SIMMs are standard and must be used in matched
pair.
For W0/W1 models, reference Ver. 1.11 is required to use
RAM's more than 16MB.
Important note regarding SIMM height.
PSU locates just above SIMM slots and there isn't enough space left for tall
SIMMs.
Do not use SIMMs taller than 25mm ( most of IBM true parity 8MB sticks are this
size.)
Please check 5560
sec of Ardent Tool for this issue reported by T. Slavotinek,
Video
No video chip is ready on the planar. PS/55 Display Adapter
B-2 ( BVE with VGA chip ) is used for 5560.
5560 doesn't have XGA chip on the planar.
AVE 32-bit slot locates beside complex riser in addition to BVE slot
which is already occupied with D/A B-2.
Genuine SCSI /A with
cache
A stock SCSI /A for -W1/W2 models is, unlike 8590, half
length 32 bit adapter with AT like 50 pin header .
ADF is usual @8eff ( 32Bit with cache ). SCSI micro code
set is 64F4376/4377. See outline HERE.
16 bit SCSI /A was used for W0 model but I don't know if it was
a long uncached card or short uncached card.
5560-N model was equipped with a short length SCSI Adapter II/A
(32bit) with 512KB cache ( which is IDed as 06G6760 in
sales leaflet and I think the part might be ether 35G2818
or 07G3063. )
Inner View
( click image to enlarge )
Photos below are inner view of my 5561-W1B with Type-B Upgrade processor
complex.
Half sized caching SCSI /32A with 50 pin header was changed to
a short caching SCSI /A -II/32A with new micro code set.
You can see an AM5x86-133 on an interposer with
a short height heat sink which runs in 160MHz inner speed ( No CPU fan but fresh air blows out from the front fan
).

Close View ; SIMM and Power Connectors
You can pull the PSU upward and then swing it down to right side like Mod. 95.
You can see Power connection is different from PS/2 Mod.90.
Tall height SIMMs are not good for 5560.
Needs clearance between SIMM and the PUS. |

Processor complex for 5560
( please see comparing
chart )
Following complexes can only be used with 5560 planar except
W0 complex which can be used for 5580 if you want.
W0 ;
P/N 79F0087, 80486DX-25MHz.
Seemed to be a Modified Type 1- J. 256K cache card available.
No overdrive socket prepared.
This complex can take 31 MHz OSC without any change of BIOS.
The Board design is same with 5580-Y complex. BIOS P/N are same each other
but just the board P/N and FUR and OSC are different ( 5580-Y0 uses
33.3MHz OSC ). |
* Original image
was outlined by Louis F. Ohland
W1 ; P/N 07G0460
FUR 95F4299, 80486SX-25MHz.
Modified Type H. 486SX CPU is loaded on the
main socket ( U8 ) and an overdrive socket is placed right
next to the main socket. Memory count is faster than
W0 complex.
No L2 cache available. |
* Original image was outlined

W2 ; P/N 07G3153
( amended on 2003.05.04)
My machine is labeled as "5561-W1B"
and has a sticker "KIT-W2B".
KIT-W2B description.
A sticker "P/N 07G3153"
and REA number is attached right on the area ( the solder side of
U8, 80486DX socket) where P/N is silk
screened on a W1 complex.
Also there is a " MPU Upgrade"
sticker attached on the blue lock lever of the complex board.
Earlier W2x models were shipped
with an i486SX-25 loaded on socket U8 and a 486-25/50 upgrade option ( ID#06G7015 ) on
socket U9. Latter models were shipped with i486DX2-50 loaded
alone on the socket U9. W1
and W2 complexes are "same" each other. |

U6
Variants from Louis's page
" Some Type-2 (92F0079)
suffer from an "incompetent DMA-chip", which is P/N 92F1428 at
position U6/GA-M on the card. Working Type-2s 92F0079 have a DMA-chip P/N
10G7808 at U6/GA-M. If U6/GA-M is 10G7808 a Turbochip should work fine.
The earlier Type-2 use the 92F1428 - which ends the experiment in
odd results permanent
I9990044, 605 FDD errors, permanent 165 errors and inability to read from
FDD). "
But Japanese
" KIT-W2B" with U6 P/N 92F1428 works fine with ;
1). DX4ODP-75
with 486SX25 on the 1st socket.
2). DX2-66
alone on the 2nd socket ( 50MHz inner clock operation )
3). DX4-100
on an interposer with VRM alone on the 2nd socket.
4). am5x86
or Cyrix 5x86 ( with voltage interposer )on the 2nd socket. There is no significant difference
between Type 2 H in Louis's page and above PS/55-W1/W2 complex. The board P/N (
or FRU ? ) and the BIOS P/N are just different
|
N ; P/N
35G2951 FRU 35G2765 80486DX2-66MHz
|
A variant of
Type 2- L?
No support for SyncroStreaming
Data transfer.
Originally equipped
in Model 556-N which was introduced to the market in Sep.1992.
The complex is also
referred as DX2-66 UpgradeType-B .

There is no over drive
socket on this complex. At the position of U9 of W1/2
complex,
N complex has solder
pads.
DMA controller chip
U6 is 34G3517 for N and
92F1428
for W1/2.
At least there are
2 versions of this complex. While I replaced the OSC to
80MHz, I noticed
that copper traces
around solder side of OSC were different, and found one board has a chip
resister and the other
doesn't. Both complexes worked fine with 80MHz OSC with
modified
BIOS ROM.
All complexes of model
5560 including N complex use EPROM.
Streaming data transfer
feature is not supported on all 5561 complexes.

CPU upgrade:
For Wxx, DX4ODP-75 can be used. You can use DX4ODP-100
but it runs in 75MHz inner speed.
N model can take DX4-100, AMD and Cyrix
with an appropriate VRM interposer which supplies 3.3v - 3.45v. As N complex has it's CPU socket at
the front edge, it's difficult to use a thick heat sink with a cooling fan in regular size. As far
as you use blue plastic air guide properly, your CPU will get fresh air flow from the front fan.
|
|
Complex upgrade:
60-W0/W1 can be replaced to -W2 or -N complex,
60-W2 can be replaced to -N complex.
60-W1/W2 complexes can be used for 5580. Associated
REF/DIAG for 5560 could not be used in this case. REF/DIAG for 5580-Wxx should be used
together with. 5580 with 60-W0 complex with 5580-Y REF/DIAG
==> No equivalent model exist but works fine.
5580 with 60-W1 complex with 5580 -W REF/DIAG ==>
5580-W0x
5580 with 60-W2 complex with 5580-W REF/DIAG ==>
5580-W2x
Attention Please, but
Following combination doesn't work !
5580 + 5560-N complex ( also referred as type-B upgrade ). So far,
there is no matched Ref/Diag for this combination, until someone
successfully build a special version after inspection Type-A Ref and
60-N Ref.
